If I had my way, I’d move them out sooner than I actually do. When the sun starts shining, I get itchy feet. It doesn’t matter how good your grow lights are, they’re never going to compete with glorious sunshine. And by this time of year, the germination shed is getting very full.

But move them out too early and they don’t “toughen up”. They sulk, drop leaves, and stall for weeks. Move them out too late and you waste the best growing window.

Temperatures matter more than dates. That’s the simplest way I can put it.

Below, I’ll walk you through the practical temperature thresholds chilli growers need, how greenhouse timing changes things and what to do if you don’t have one. I’ll also share my lazy way to harden off so you can spend more time growing and less time fussing.

Quick answer: In the UK, don’t move chilli plants outside until frost risk has passed for your region (often mid-April in the south, May or later further north). Even then, aim for nights consistently above 10°C and daytime temperatures heading toward 16°C or higher. The real growth sweet spot is 20°C to 27°C, which for most of the UK means mid-June onwards.

UK Last Frost Dates: Why Timing Varies Across the Country

The UK is roughly comparable to USDA growing zones 8 or 9, but local conditions vary a lot. Coastal gardens, urban heat islands, valleys, exposed hilltop sites… all different. The most important detail to nail down first is your last frost date.

As a rough guide:

• Southern England: often around March to mid-April.
• Midlands & Northern England: commonly mid-April to late April.
• Scotland and Northern Ireland: can push toward May to late May.

Where I am (the Midlands), mid to late April is my realistic limit for timing outdoor moves. It’s about the limit of what I was willing to accept when we moved here. I wouldn’t go any further north, because that really does create some extra challenges.

What a lot of people miss is that your last frost date is only your “don’t die” line. It’s not your “start growing well” line. Plants need more than just survival temperatures to actually do anything useful.

The Temperature Thresholds That Actually Matter

Frost isn’t just about “cold air”. The real problem is when the plant’s root system gets near freezing. If roots freeze, it’s game over.

Here are the temperature thresholds that guide my decisions:

Temperature	What Happens
0°C	Frost can kill, especially plants in pots where roots are more exposed.
6°C	Survives, but expect leaf drop and flower drop.
10°C	Prolonged periods here can trigger dormancy behaviour.
13°C	Alive, but slow and miserable. Won’t thrive.
16°C	The “magic number” where most chilli species start growing again.
20°C to 27°C	The sweet spot for strong growth, flowering, and fruiting.
32°C+	Heat stress becomes a factor (rare in the UK, but it happens).

Why a Single Cold Night Isn’t the Real Problem

A single chilly night isn’t always the problem. A quick dip below 10°C overnight is usually fine and most of the time the soil will have enough latent heat to keep root temperatures a bit higher anyway. The real issue is when the 24-hour average sits around 10°C or below for a sustained period. That’s when your plants stall hard. They’re not dying, but they’re not growing either and the longer they sit at that temperature, the longer it takes them to come out of dormancy once conditions recover. In a short UK season, that lost time adds up quickly.

If You Have a Greenhouse, You Can Move Earlier (But It’s Not Magic)

A greenhouse can buy you a few extra weeks on each end of the season, but it’s not some magical thing. It still gets very cold in there at night unless you have a heater.

My Greenhouse Strategy

I aim to move plants into the greenhouse about 2 to 3 weeks before my last frost date. I use a small heater set to the frost setting so the greenhouse stays above roughly 4°C. You don’t need it to be tropical in there (which would cost an absolute fortune), just enough that if temperatures dip, the frost setting kicks in and keeps the worst of it away.

There’s also a practical benefit in how greenhouses behave during the day: the soil warms up and acts like thermal mass. That means even if nighttime temperatures dip to around 3°C to 4°C, the roots don’t crash instantly because the soil retains some of that daytime warmth.

No Greenhouse? You’ve Still Got Options (Watch the Soil Temp)

If you don’t have a greenhouse, don’t worry. I’ve used simple protective setups before and they can do a solid job. In some of my earlier videos, you’ll see I had a plastic greenhouse that cost me about £20 and it worked perfectly fine.

• Cold frame: helps protect from wind and cold air, and traps a bit of warmth.
• Bottle cloches: grab a 2-litre Coke bottle, cut off the bottom and pop it over your seedling. Cheap and surprisingly effective.
• Cheap plastic greenhouse: the kind you can pick up for around £20. Not fancy, but it does the job if you manage ventilation.
• Raised beds: if you plant directly into the ground, the soil can stay cold for months. Raising the bed warms the soil up quite a bit faster.
• Pots: my favourite, because you can control temperatures far more effectively than ground planting. Even inside that cheap plastic greenhouse I mentioned, I used pots and that’s what helped me maintain temperatures and grow some amazing chilli plants.

One thing to keep in mind: covering the plant helps the air temperature, but cold soil still punishes roots. The air cover is only half the story. If you’re planting outside without a greenhouse, pots or raised beds can make a real difference to root zone temperature.

When to Move Chilli Plants Outside in the UK (The Practical Rule)

Even after the risk of frost passes, I don’t treat “no frost” as the finish line. Chilli plants grow best when temperatures are consistently in the 20°C to 27°C range.

For the UK, that usually means you start seeing the real boost in flowering and fruiting around mid-June (assuming the weather cooperates). After that, you can often expect strong growth through June, July, August, and sometimes into September.

The Decision Process I Use

1. Check your last frost date for your region (the rough regional guide above is enough).
2. If you’re moving earlier than that, you need night protection: greenhouse, frost heater, cold frame or cloches.
3. Aim for nights that aren’t regularly dipping into single digits, and especially avoid long stretches where averages sit around 10°C.
4. If you want real growth, wait until you’re closer to that 16°C restart point and then into the 20°C to 27°C range.

Reality Check for the UK

Even when frost risk is “done”, your plants often don’t get going until mid-June, depending on the year. That’s when you usually see massive growth and a lot of flowering and fruiting happening. If you’ve been growing for a few seasons, you’ll know that feeling of waiting… and waiting… and then suddenly everything kicks off at once.

The Lazy Way to Harden Off (UK Edition)

Hardening off is basically: stop babying the plant, but don’t shock it.

Most people do the full shade-to-sun routine, moving trays in and out every day. Fair enough. I’m lazier and it’s actually one of the reasons I like to bring my plants out a little earlier than some people might.

Why the Lazy Method Can Work Here

Earlier in the season, the sun is still quite low in the sky. It’s not directly overhead like it’s going to be later in summer. It comes in at an angle, so the light is genuinely less intense than it’ll be in a couple of months. That means plants can acclimatise without you doing a daily marching routine with trays.

My Lazy Hardening Off Method

If I’m moving plants out by mid-April at the latest (Midlands area), I can often just take them straight out. I don’t shade anything. The plants acclimatise naturally because the sun isn’t strong enough to cause damage at that time of year. I focus more on temperature protection than sun protection at that stage.

I’ve covered this in more detail in my “Hardening Off the Lazy Way” video, so have a look at that if you want the full walkthrough.

When You Should Harden Off More Carefully

If you’re moving plants out later in the year, when the sun is punchier, you should acclimatise more carefully:

• Put plants outside in sunshine for part of the day.
• Move them into shade or shelter for the rest.
• Increase the exposure over several days.

If you live somewhere like Florida or Spain where you get strong sunshine even earlier in the year, you’d likely fry your plants taking them straight outdoors without hardening off. Shade netting becomes essential in those climates, not just a nice idea.

6 Common Mistakes That Wreck Chilli Plants in Spring

1. Using your last frost date as the only rule. Temperatures can still be too low for growth even after frost risk has passed, leading to weeks of stalling.
2. Forgetting that pots freeze faster than soil. Roots in pots are more exposed than roots in the ground. They suffer first.
3. Moving plants out, then leaving them during a cold snap. The classic “I’ll risk it” moment. If a sharp cold spell is forecast, bring them in or cover them.
4. No ventilation under cloches or mini covers. A warm day plus trapped humidity equals problems. Pop the lid or open the end during the day.
5. Thinking “survival” equals “growth”. Temperatures between 6°C and 13°C might keep them alive, but they won’t be thriving. That’s time you can’t get back in a short UK season.
6. Planting straight into cold ground without protection. If you’re going outside without a greenhouse, the ground soil can stay cold for months. Pots or raised beds help you avoid this.

Quick tip while you’re planning your outdoor move: get some marigolds in alongside your chillies. They’ll attract hoverflies and ladybugs, which will help keep aphids in check once your plants are outside. It’s one of the easiest things you can do to give your plants a better chance.

Quick Checklist: Move Your Chilli Plants Outside with Confidence

• No frost risk, or you’ve got night protection sorted.
• Avoid prolonged periods where averages sit around 10°C or below.
• Aim for 16°C as a restart temperature, then 20°C to 27°C for strong growth.
• Use pots or raised beds if soil temperature is holding you back.
• Harden off carefully if the sun is strong when you move them out.

Frequently Asked Questions

How early can I move chilli plants outside in the UK?

If you have a greenhouse, moving plants out about 2 to 3 weeks before your last frost date can work, as long as nights are protected with a frost heater or similar. Without a greenhouse, wait until frost risk is very low and temperatures are trending warmer.

What temperature kills chilli plants?

Around 0°C is the danger zone. The critical point is when the root system drops below freezing and this happens faster in pots than in ground soil.

Will chillies survive at 6°C?

Usually yes, but expect stress. Leaf drop and flower drop are common at this temperature. They’ll survive, but they won’t be happy about it.

When do chilli plants start growing again?

16°C is a useful benchmark where most common chilli species resume growth. The real sweet spot for strong flowering and fruiting is 20°C to 27°C.

Do I need to harden off my chillies in the UK?

It depends on timing. If you’re moving plants out early in the season (around mid-April in my area), the sun is still low in the sky and less intense, so you can often skip the gradual shading routine. If you’re moving them out later when the sun is stronger, a gradual exposure over several days is worth doing.

What’s the best alternative to a greenhouse?

A cold frame is a solid option. Cloches work too, even a 2-litre bottle with the bottom cut off. A cheap plastic greenhouse (around £20) does a decent job if you ventilate it. If you’re planting into the ground, raised beds help the soil warm faster. Pots give you the most control overall because you can move them around as conditions change.

Can grow lights replace sunshine?

Grow lights are brilliant for getting seedlings started indoors, but they’re never going to compete with real sunshine. Once conditions are warm enough outside, your plants will do far better in natural light.

If I can leave you with one guiding idea, it’s this: timing isn’t just a calendar date. It’s about protecting roots from frost and then steering your plants into the temperature range where growth actually restarts. Get that bit right and the rest follows.

I made that mistake for years. Loads of growth, very little fruit, and a creeping feeling that the plants were laughing at me. Once I simplified my feeding approach, the results changed pretty quickly.

This is the feeding plan I actually use: when to start, what to use, how often, and how to read the plant when something’s off. No overcomplication, no expensive specialist products you don’t need.

How to feed chilli plants: quick summary

Seedlings: plain water only. A light seaweed feed at quarter strength is fine after a couple of weeks.

After potting up: let fresh compost do the work for 3-4 weeks before adding liquid feed.

Final pot: start liquid feed 3-4 weeks after the last pot-up. Begin at half strength.

In season: alternate feed and plain water. Never feed every watering.

Late season: reduce feeding and watering so existing fruit ripens naturally.

Key NPK ratio: aim for roughly 3:1:5 (N:P:K), with high potassium once flowering starts.

Feeding is a top-up, not the main course

A good soil mix does the heavy lifting. Liquid feed fills in the gaps as the season progresses and it’s not supposed to be doing the heavy work from the start.

Feed too early or too heavily and you get leafy, lush plants that flower late and fruit reluctantly. Salt builds up in the compost, roots get stressed and you end up chasing deficiencies that the overfeeding caused in the first place. It’s a frustrating loop.

The mindset shift that helped me most: feed less than you think you should and only increase if the plant shows you it needs more. A slightly underfed plant still sets pods. An overfed one often won’t.

Understanding NPK: what actually matters for chillies

Every fertiliser label shows three numbers: nitrogen (N), phosphorus (P) and potassium (K), as percentages by weight. A 4-1-6 product contains 4% nitrogen, 1% phosphorus and 6% potassium.

• Nitrogen (N): drives leafy growth and builds the plant’s structure. The one most people oversupply. Too much nitrogen and you’ll get a beautiful, bushy plant with very few pods.
• Phosphorus (P): supports roots and early development. Most decent UK composts already have enough and you rarely need to add extra.
• Potassium (K): this is the one that matters most for chilli growers. Supports flowering, fruit set, fruit quality and stress tolerance. Once your plant starts flowering, potassium should be the dominant number.

The ratio I aim for: roughly 3 parts nitrogen to 1 part phosphorus to 5 parts potassium. Keep an eye on that K number.

Which feed to use

You don’t need anything specialist. These are the options that work well for UK growers:

Tomorite is the one I’d recommend to most people starting out. It’s cheap, it’s everywhere and the ratio is close to what chillies actually need. Start at about half the dilution shown on the bottle when you first begin feeding. Chilli Focus is also solid if you want something formulated specifically for capsicums.

Miracle-Gro’s high nitrogen content makes it less ideal once flowering starts. The plant already wants to shift energy toward fruit, and a nitrogen-heavy feed pulls it back toward leaves. It won’t cause disaster at low doses, but switch away from it as flowering begins.

When to start feeding: the seasonal rhythm

Seedling stage

Plain water. That’s it. Seed compost has enough nutrients for the first few weeks and feeding too early is one of the most common mistakes beginners make. You can add a very light seaweed feed at quarter strength after a couple of weeks if you want to, but genuinely, it’s not essential. Watch: The Right Way to Water Your Chilli Plants.

After each pot-up

Every time you move a plant into fresh compost, the clock resets. A mix amended with slow-release organics (chicken manure pellets and fish, blood and bone are what I use) will feed the plant for three to four weeks without any liquid feed on top. Hold off and let the compost work.

Final pot

Start supplemental liquid feeding three to four weeks after the last pot-up into the final container. Begin at half strength and build up gradually only if the plant responds well. There’s rarely a need to go above full label strength and going beyond it causes more problems than it solves.

Alternate feedings with plain water. One watering with feed, the next without. This is the single change that makes the most difference for most growers. It gives the plant time to process what it’s already been given and prevents salt from accumulating in the compost.

Late season

Pull back. Reduce feeding frequency and watering as the season winds down. You want existing fruit to ripen, not new vegetative growth. Keeping the feed going at full strength into autumn just delays harvest.

Blossom end rot: what it actually is

That dark, sunken patch at the base of a chilli is gutting to find, especially after you’ve put months into the plant. The good news is it’s not a disease and it’s not the end of the plant. It’s a calcium delivery problem.

Calcium moves passively with water through the plant and during periods of stress, rapid growth or irregular watering, it tends to favour leaves over fruit. Heavy feeding makes this worse. Salt build-up from overfeeding impairs calcium uptake even when there’s plenty of calcium in the soil.

Prevention is much easier than the cure. Work fish, blood and bone into your soil mix at the start of the season. It provides slow-release calcium across the whole growing period. Pair that with consistent watering, because calcium delivery tracks closely with water movement through the plant.

Eggshells mid-season won’t help. They break down far too slowly to correct an active deficiency. Prevent the problem from the start.

Magnesium and Epsom salts

Magnesium sits at the centre of every chlorophyll molecule and it’s what keeps leaves green. A deficiency shows up as yellowing between the veins on older leaves, with the veins themselves staying green. If you’re seeing that pattern, magnesium is usually the culprit.

Calcium and magnesium interact and too much of one can block uptake of the other. Worth knowing if you’re adding a lot of calcium supplementation.

If you need to correct a deficiency, a foliar spray of magnesium sulfate (Epsom salts) works quickly. About one teaspoon per litre, every two to three weeks. Only spray when you can see signs of deficiency. Healthy green leaves don’t need it.

Micronutrients and pH

Chillies also need iron, manganese, copper, zinc, boron and molybdenum in small amounts. A deficiency in any of these can limit growth or fruit quality even when the main NPK numbers look right.

Iron deficiency is the one to watch for. It shows as yellowing of young leaves with green veins, appearing on new growth rather than older leaves. This usually means pH is too high and locking out iron, rather than iron actually being absent from the soil.

A seaweed feed early in the season covers most trace element bases. Good complete feeds like Tomorite and Chilli Focus include them too. In container growing, micronutrient deficiencies are uncommon if you use a decent feed and refresh compost each season. Problems build up when you reuse the same soil for years without replenishing organic matter, or when pH drifts high.

Common mistakes and how to avoid them

• Feeding onto dry compost: never apply concentrated feed to bone-dry soil. Water first, give it 20-30 minutes to soak through, then feed. Concentrated nutrients hitting dry roots cause burn.
• Starting too early: seedlings and newly potted plants rarely need liquid feed. Waiting until plants are established in the final pot prevents most overfeeding problems before they start.
• Feeding every watering: alternate feed and plain water. One with feed, one without. Every time. This one change fixes a lot.
• Ignoring what the plant is telling you: feeding isn’t a fixed schedule, it’s a response to what you see. Healthy, dark green leaves don’t need more nitrogen. Pale new growth does. Read the plant rather than the calendar.

Reading your plant: what the leaves are telling you

Plants are pretty good at communicating when something’s off, once you know what to look for:

• Yellowing lower leaves: usually nitrogen. The plant is pulling nutrients from old growth to support new. Increase your N feed slightly.
• Yellowing between veins on older leaves, with veins staying green: magnesium deficiency. Try an Epsom salt foliar spray.
• Yellowing on new growth with green veins: iron deficiency. Check pH, it may be too high.
• Leaf edges curling or browning: potassium deficiency, or salt build-up from overfeeding. Flush the pot with plain water and hold off on feeding for a week or two before reassessing.

Three rules that cover most situations

1. Wait before you start feeding. Don’t begin liquid feed until plants are in their final pot, then wait another three to four weeks after that last pot-up. Fresh compost is doing the work, so let it.
2. Always start at half strength. Easy to increase, impossible to undo. Half the label dose is the right starting point every time you switch to a new feed or come back from a break.
3. Alternate with plain water. One watering with feed, the next without. Every single time. This one habit prevents more problems than any other.

Quick-reference feeding checklist

• Seedlings: plain water. Optional light seaweed at quarter strength after a couple of weeks.
• After potting up: trust the compost for 3-4 weeks. No liquid feed needed.
• Final pot: begin liquid feed 3-4 weeks after the last pot-up, at half strength.
• Throughout the season: alternate feed and plain water. Foliar magnesium only when you see signs of deficiency.
• Late season: reduce feed and watering. Let the fruit ripen.

How to feed chilli plants: Frequently asked questions

When should I start feeding my chilli plants?

Three to four weeks after the last pot-up into the final container. Before that, decent amended compost covers the plant’s needs. Seedlings need only plain water, or a very light seaweed spray at most. Watch Why Pot Up (4 minute bitesize video) to find out why potting up in stages is so important.

What is the best feed for chilli plants in the UK?

Tomorite is the most practical option for most growers. It’s cheap, widely available and has an NPK ratio close to what chillies need. Chilli Focus is a solid alternative if you want something formulated specifically for capsicums. Either way, start at half the recommended dilution.

How often should I feed chilli plants?

Alternate feed and plain water. One watering with diluted feed, the next with plain water. Never feed every time you water, as it leads to salt build-up and causes the deficiencies you’re trying to prevent.

How do I prevent blossom end rot?

Work fish, blood and bone into your soil mix at the start of the season for slow-release calcium. Keep watering consistent, as irregular watering is a key trigger. Avoid heavy feeding that drives rapid growth, because calcium delivery can’t keep pace with fast-expanding fruit tissue.

Can I use Epsom salts on chilli plants?

Yes, as a targeted correction when you can see signs of magnesium deficiency. That’s interveinal yellowing on older leaves. Foliar spray at about one teaspoon per litre, every two to three weeks. Don’t spray preventatively on healthy plants.

Can I overfeed chilli plants?

Yes and it’s the most common feeding mistake. Overfeeding causes excessive leafy growth, salt build-up in the compost, root burn and reduced fruit set. A slightly underfed chilli plant still sets pods. An overfed one often produces little but leaves.

Final thought

The best growing seasons I’ve had weren’t the ones where I fed the most. They were the ones where I got the timing right, started light and let the plant show me what it needed. Chillies are tougher than people think and they don’t need coddling, they need consistency.

If the feeding is sorted and you’re still not getting the results you want, the next thing to look at is usually watering or potting-up timing. Those three things together cover most problems. Get those right and the pods follow.

You haven’t. Leggy seedlings are one of the most common problems chilli growers run into and they’re almost always fixable, sometimes within days.

This guide covers why it happens, how to rescue seedlings that have already stretched, and how to set things up so it doesn’t come back.

What Does “Leggy” Actually Mean?

A leggy chilli seedling has:

• A long, thin stem with wide gaps between the leaves.
• A plant that leans, flops, or can’t hold itself upright.
• Sometimes pale or washed-out colouring.

It’s not a variety thing. It’s not your fault either, exactly. It’s your seedling telling you something in its environment is off and nine times out of ten, that something is light.

Why Chilli Seedlings Go Leggy

1. Not Enough Light (the Big One)

When light is too weak, chilli seedlings stretch upward trying to find more of it. They’re doing exactly what they’re supposed to do in the wild, growing toward the sun. The problem is that in your propagator or on your windowsill, there’s not enough sun to actually reach.

Common causes:

• Windowsill light (especially in the UK between November and March) that’s just too weak.
• A grow light that’s further away than it should be.
• Light that’s only on for a few hours a day.

If you change nothing else, change the light. Everything else is secondary.

2. Too Warm With Weak Light

Heat mats and warm rooms are great for germination. But once the seedlings are up, warmth speeds growth and if the light isn’t keeping pace, that growth becomes spindly rather than compact. Basically, the plant is growing fast but not building anything useful.

3. No Airflow

Still air encourages thin stems. A bit of movement, even just a small fan on low, helps seedlings develop thicker, sturdier growth. It’s the same reason plants grown outside tend to be stockier than ones raised indoors.

4. Overwatering and Humidity Domes Left On Too Long

Wet compost combined with a sealed humidity dome can cause weak stems and, in some cases, little bumps or aerial roots forming up the stem. The plant is essentially trying to find moisture wherever it can.

How to Fix Leggy Chilli Seedlings

Step 1: Fix the Light Immediately

If you’re using a grow light, move it closer. If you’re on a windowsill, consider adding a proper light. UK spring daylight, especially January through March, isn’t strong enough for sturdy seedlings on its own.

You want light coming from above, not sideways. Sideways light is why plants lean toward windows.

Step 2: Add Gentle Airflow

A small fan on its lowest setting, just enough to make the seedlings wobble slightly, will start building stronger stems within a week or two. Don’t point it directly at them at full power. Just a light, consistent breeze is all you need.

Step 3: Pot Them Up Deeper (The Main Rescue Move)

This is the one most people don’t know about. Chillies can grow new roots along a buried stem. That means when you pot up, you can bury the leggy section underground and end up with a much more stable, better-rooted plant.

When you pot up, bury the stem right up to the first true leaves.

Not the seed leaves (the round cotyledons that came first). The first proper chilli leaves. Keep those above the soil; let everything below go under.

How to Pot Up a Leggy Seedling Properly

1. Choose a deeper pot than you think you need. You need enough depth to bury that stem without cramming the roots.
2. Handle it by a leaf, not the stem. Stems bruise easily. Leaves are more forgiving.
3. Plant it deep, up to the first true leaves. Everything below that line goes underground.
4. Firm the compost gently. Remove big air pockets but don’t compact it.
5. Water once to settle it in, then hold back. Let the compost dry a bit before the next watering.

You can overdo it. Don’t bury the true leaves and don’t keep the compost soaking wet after potting up. Wet compost + buried stem = rot risk. The goal is deep enough to stabilise, not underground entirely.

Why Are There Roots Growing Above the Soil?

This one comes up in the community fairly often. If you can see little bumps or root-like growths forming up the stem, it’s almost always down to too much moisture early on.

Typical causes:

• Humidity dome left on for weeks after germination.
• Compost kept constantly wet.
• Very little airflow in the grow space.

If you’re potting up anyway, just bury those aerial root bumps along with the rest of the stem. They’ll turn into proper roots once underground.

How to Prevent Leggy Seedlings Next Time

None of this requires expensive kit. It’s just about getting the conditions right from the start.

• Light: Strong, from above, switched on early after germination. Keep your grow light close enough to matter.
• Temperature: Warm for germination, slightly cooler once they’re up. Not cold, just not a sauna either.
• Watering: When needed, not on a schedule. Check the compost. Let the surface dry slightly between waterings.
• Airflow: A gentle fan. Thin stems are built in still air; thick ones need a bit of movement.

If you only do one thing: fix the light.

Common Mistakes (Easy to Make, Easy to Fix)

• Leaving the humidity dome on for ages because the seedlings look comfortable.
• Running a heat mat after germination when the light isn’t strong enough to match the warmth.
• Keeping the grow light far away out of fear of burning the seedlings (most growers do this).
• Watering on autopilot instead of checking whether the plant actually needs it.

Seedlings don’t need constant attention. They need the right conditions. Get those right and the plant does the hard work.

Quick Recap

If your chilli seedlings are already leggy:

1. Move the light closer (or add one).
2. Add gentle airflow.
3. Pot up deep: bury the stem to the first true leaves.

To stop it happening again:

1. Strong light as soon as seeds germinate.
2. Don’t run it too warm with weak light.
3. Avoid constantly wet compost.
4. Add airflow.

This kebab shop chilli sauce recipe is chunky rather than smooth, dead easy to customise and keeps well in the fridge for the week. Use fresh homegrown chillies if you have them, frozen ones work a treat too, or grab whatever red chillies are available at the supermarket.

No fancy kit required. No fermentation. Just tons of flavour, fast.

Why This Kebab Shop Chilli Sauce Works

The short cook time is the key. Just 15 minutes on a gentle simmer is enough to meld the tomato sweetness, garlic depth and chilli heat together, while knocking the raw edge off the vinegar. It’s long enough to develop flavour, short enough that the sauce keeps its brightness.

The olive oil is optional, but worth including if you want that slightly silky, luxurious mouthfeel you get from a proper kebab shop sauce. Cumin and paprika do the heavy lifting on the spice profile, warm, earthy and just complex enough to taste like you’ve been at it all afternoon.

Which Chillies Work Best?

You want chillies with a balance of sweetness and heat rather than pure fire. CC Piri Piri, Ring of Fire, Jalapeños, or Cayenne all work well. If you’re using CC Jalapeños, start with six and add more if you want more kick. For milder shop-bought Jalapeños, you might want seven or eight.

Frozen homegrown chillies are absolutely fine here since the sauce is cooked. If you grew more than you could eat this season, this is a perfect recipe to work through the stash.

Pro tip: Don’t over-blend. A rough, chunky consistency is what gives kebab shop chilli sauce its authentic character. Smooth it out too much and it loses that freshness and body.

• Transfer to a saucepan and bring to a gentle simmer, stirring occasionally. Simmer for 15 minutes. If you want a thicker sauce, just let it go a bit longer.
  
• Cool and jar it up. Let the sauce cool slightly, then decant into a clean jar. Keeps in the fridge for about a week.

Taste and Adjust

• Once it’s had its 15-minute simmer, give it a proper taste. Every batch of chillies is different, and tinned tomatoes vary in sweetness and acidity. Here’s how to balance it:
• Too sharp? Add a pinch more sugar.
• Needs more brightness? Add a splash more vinegar, a little at a time.
• Want it creamier? Increase the olive oil slightly.
• Too spicy? Stir a spoonful of mayo or yoghurt through when serving.

Ways to Use Your Kebab Shop Chilli Sauce

• The classic, drizzle generously over grilled meat, salad and flatbread.
• As a dip for chips or pittas.
• With pork and sauerkraut for a punchy, tangy lift.
• As a base for a quick spicy tomato stew: add stock, whatever veg you have and simmer.

Tips and Variations

• Tomatoes: Tinned tomatoes give you consistent acidity every time. If using fresh, cook a little longer to break them down.
• Spice level: Swap to milder chillies or reduce the quantity. Smoked paprika instead of regular adds another layer.
• Texture: Rough blend is the authentic move. If you prefer smooth, blend longer and strain.
• Storage: Use a sterilised jar and keep it refrigerated. Best within a week, freezes well for up to three months.

Frequently Asked Questions

How long does kebab shop chilli sauce keep in the fridge?

About a week in the fridge, stored in a clean jar. No preservatives beyond vinegar and salt, so fresher is better for flavour. Freeze in portions for up to three months if you want to make a bigger batch.

Can I use fresh tomatoes instead of tinned?

Absolutely. Use ripe tomatoes and cook a little longer to break them down. Tinned tomatoes are just more convenient and give consistent results.

Can I make this sauce without olive oil?

Of course. Vegetable oil works fine. The olive oil adds creaminess and a bit more flavour, but it’s optional.

How do I reduce the heat without losing flavour?

Remove seeds and membranes from your chillies before blending, use fewer chillies, or add a touch more sugar. Serving with something creamy like mayo or yoghurt on the side also tames the heat without changing the sauce itself.

Can I freeze homemade chilli sauce?

Yes. Freeze in small portions for up to three months. Thaw in the fridge overnight and give it a quick stir before serving.

Quick Kebab Shop Chilli Sauce Recipe Summary

Roughly blend 6 chillies, 6 garlic cloves, 1 tin chopped tomatoes, 1 tbsp tomato purée, 2 tbsp olive oil, 1 tbsp white wine vinegar, 1 tsp salt, 1 tsp sugar, 1 tsp cumin and 2 tsp paprika. Simmer for 15 minutes. Cool, jar, refrigerate.

Making your own kebab shop chilli sauce means you control the heat, the freshness and exactly what’s going into it. No additives, no watery flavourless disappointment, just a tasty sauce that’s worth the 15 minutes.

If you’ve got homegrown chillies and you’re wondering what to do with them, this is one of the quickest and most satisfying ways to use them. Adjust the heat to your liking, experiment with the spice ratios, and make it your own.

People overcomplicate chilli growing. After decades of doing this and getting it wrong as often as getting it right, I can tell you that the chilli growing fundamentals are genuinely simple. Yes, there are things you can add to improve your results. But you don’t need them to get started and you don’t need them to grow a decent harvest.

What You Actually Need (The One-Line Version)

Stick a seed in some soil, keep it warm until it germinates, give it light and water, feed it now and then. That’s it. By the end of the season, you’ll have chillies.

Everything below is the practical detail behind that one line.

If you’d rather watch my video on this then click below:

1. Seeds: Free or Bought

Everything starts with a seed. You can grab quality seed from chillichumpseeds.com or simply save seeds from a chilli you’ve already eaten.

The key: use fully ripe fruit. Jalapeño, for example, are green when unripe and red when ripe. Cut it open, take a few seeds, let them dry out fully, then plant.

Supermarket chillies are often cross-pollinated, so you might not get an identical plant, but you’ll still get healthy, productive results, and possibly something completely unique. Best of all, since you already bought the chilli to eat, the seeds are essentially free. For more information on saving chilli pepper seeds – take a look at this article: Save Pepper Seeds – How to Harvest Chilli Seeds.

2. Germination: Warm and Moist Is All You Need

Chilli seeds love warmth, especially heat-lovers like habaneros and other Capsicum chinense varieties. Drop seeds into cold compost on a draughty windowsill and they’ll sulk for weeks, or rot.

You don’t need a fancy propagator. Here’s the no-fuss method:

• Fill a small takeaway tub with cheap seed compost (not garden soil).
• Plant seeds at roughly the same depth as the seed’s length.
• Keep the compost damp, not soaked.
• Cover with cling film or a lid to hold in moisture.
• Place somewhere warm. The top of the fridge works brilliantly, or near anything that gives off gentle heat.

When the first green shoots appear, remove the cover and move them somewhere bright.

Check out Germinate Chilli Pepper Seeds Like a Pro for more detailed info.

3. Light: The Thing Most People Get Wrong

Once seedlings are up, light is everything. A south-facing windowsill (north-facing if you’re in the southern hemisphere) is your best free option.

If your seedlings are growing tall and spindly with big gaps between the leaves, that’s called being “leggy” and it just means they need more light. Move them closer to the window, or supplement with a cheap desk lamp or basic LED shop light positioned close to the plants.

You don’t need expensive LED grow panels to start. In my early days I used fluorescent tubes and cheap CFLs. They work.

4. Potting Up: When to Move Them On

When your plant has three or four sets of true leaves, it’s time for a bigger pot.

You don’t need special containers. Old ice cream tubs, takeaway boxes, even a cut-down water jug are all perfectly good. I tend to pot up in stages to encourage strong root development, but if you want to keep things simple, sowing into a larger pot from the start works too.

Just make sure whatever you use drains well. Use decent compost or garden soil. Chillies are hungry plants and will thank you for it.

5. Feeding and Watering

Two things kill more chilli plants than anything else: overwatering and not feeding at all.

Watering: Keep the soil moist but never waterlogged. Always let excess water drain away freely. If in doubt, let the top inch of soil dry out before watering again.

Feeding: Tomato feed is my go-to, it’s cheap and works brilliantly. Seaweed fertiliser is another favourite, gentle enough to use from seedling stage all the way through harvest. Start at half strength and feed every few waterings. Don’t overdo it.

6. Flowers, Fruit and Saving Seed

By the end of the season, flowers will set and develop into pods. Pick them when they ripen and enjoy them.

Want to grow the same plants again next year? Save seeds from fully ripe pods, dry them out properly and store in a cool, dry place. Do this season after season and you start developing plants that are genuinely yours, adapted to your climate, your setup, your taste.

The Bare Minimum Grow Chillies at Home Checklist

Everything you need to get started:

• Seeds: bought, or saved from a ripe supermarket chilli.
• Cheap seed compost: avoid raw garden soil for germination.
• Small containers: for germination, larger pots for growing on.
• Warmth: top of the fridge or somewhere that gives off gentle heat.
• Light: a sunny windowsill or basic lamp to stop seedlings going leggy.
• Simple fertiliser: tomato feed or seaweed, used at half strength.
• Patience: and a watering routine: moist, not waterlogged.

What to Add When You’re Ready to Level Up

Once the basics feel natural, there’s plenty you can add to improve your results: propagators, proper grow lights, a greenhouse or polytunnel, basic automation for watering and temperature. All of those things help. None of them are required to grow a decent plant and a good harvest.

FAQ

Can I use seeds from a supermarket chilli?

Yes. Harvest from a fully ripe pod, dry the seeds and plant. They may not grow true if the parent was cross-pollinated, but you’ll still get healthy plants and possibly something completely new and interesting.

How deep should I plant chilli seeds?

A reliable rule of thumb: as deep as the seed is long. That works for most small seeds.

Where’s the best spot to keep seed trays warm?

Top of the fridge is a classic. Anywhere that gives off gentle, consistent heat will do. Keep trays covered until germination, then remove the cover and move them straight to light.

My seedlings are leggy, what do I do?

They need more light. Move them to a sunnier windowsill, or get a basic lamp positioned close to the plants. Give them as many hours of good light as you can.

What fertiliser should I use?

Tomato feed or seaweed fertiliser. Start at half strength, feed every few waterings, and make sure the compost drains freely so roots don’t sit in wet soil.

Can I plant straight into a large pot from seed?

Yes, but it’s harder to keep a large pot warm during germination. Starting small and potting up is usually easier, and tends to produce stronger root systems.

If this helped, and you’d like guides on making hot sauce, fermentation or low-tech growing setups at home — let me know in the comments. Until next time, stay spicy.

I know what you’re thinking: “Shaun, it’s freezing outside, surely starting chilli seeds now is madness?” Your chilli seeds don’t actually care what’s happening outside though. They care about three things: warm compost, steady heat and not drowning. Everything else is just making your life easier so you can repeat the process next year without tearing your hair out.

This article will give you some of the basics and some of my methods with links to other resources to help you get the 2026 season off to a great start!

Why I Start Seeds in the Dead of Winter

Superhot chillies need time. If you want big, healthy plants that actually give you ripe pods before the season ends, you need to get them going early. Simple as that.

The trick is understanding that you’re not growing anything outside yet. You’re just creating this little warm bubble where seeds can wake up and get cracking. If you’ve got a heated propagator (or even just a heat mat) and some grow lights, what’s happening outside becomes completely irrelevant. It’s all about the temperature where the seed is sitting – in the compost.

For more detailed info, read ‘When to Plant Peppers – The Best Time‘ and ‘Planting Super Hot Chilli Pepper Seeds: A Comprehensive Guide‘.

Three Rules for Quick and Strong Chilli Seedlings

When I’m sowing at the beginning of the season, I stick to three basics which helps everything else fall into place and gives me a brilliant start to the season:

First up, warm, airy compost. Your standard multipurpose stuff can be a bit dense and heavy. Dense compost holds water. Too much water sitting around seeds slows germination and can suffocate the roots before they even get going. So I do two things to it: I sieve out the lumpy bits (so every cell feels the same), and I mix in a handful of vermiculite. Basically you’re turning “muddy sponge” into “fluffy sponge”, and seeds absolutely love fluffy.

Second, organisation. Sounds boring, I know. But when you’re sowing hundreds of seeds, if you don’t have a system, you’ll end up with labels that don’t match, varieties in the wrong cells, and this one tray of “mystery chillies” that you’ll spend all season pretending was intentional. I plan the tray layout before I plant anything: top left to bottom right, every time. I keep my seeds grouped by variety in little containers, so I’m not rummaging around mid-sow trying to find the next packet.

This is where SeedsIO really earns its keep for me. I use the tray planning feature to map out each cell before planting anything. I can tag trays with colours and IDs like “T1 (green)”. That way I know exactly what’s where, and next year I can just do it again without having to think too hard about it. Fast sowing is great. Fast sowing without mistakes is better.

Third, steady heat and humidity. I set my propagators to 28°C. Thermostats don’t hold one perfect number, mine usually floats between 27-29°C, and that’s absolutely fine. This combination of warmth and high humidity is what gets you faster, more even germination.

Can it be too hot? Yes it can, but you would be surprised how hot you can go! However I would try stay below 32℃ (90℉)

The Bit Most People Skip: Warm the Compost First

This is going to sound obvious but honestly, most people miss it: cold compost is a germination killer. While you will still get germination, it will just take longer.

Before I sow anything, I put the filled trays into the propagator area for at least 24 hours. Why? Because if your compost takes a full day to warm up after you’ve already sown the seeds, you’ve lost time straight away. When you start with warm compost, you get quicker sprouting, more even germination and way less of that “why are only three seeds doing anything?” panic that we’ve all had.

My Sowing Workflow (What I Do Every Time)

Here’s exactly what I do, in order:

1. Plan the tray layout in SeedsIO – get the varieties and cell positions mapped out.
2. Warm the filled compost in the propagator or grow area for 24 hours.
3. Make the holes with a dibber or pencil (Rule of thumb: twice the depth as the length of the seed).
4. Soak seeds appropriately (longer for older seeds. Fresh seeds don’t strictly need this, but it does help).
5. Label trays clearly (this saves so much hassle later).
6. Into the propagator at target temperature.

That’s it. Nothing fancy. Just repeatable and effective.

Propagator Settings: what I run for Superhots

I run my 100W propagators at 28°C. These particular ones are brilliant because they help keep temperatures stable even when the potting shed is cold. The Stewart Variable propagator is a favourite of mine. But if your seed starting space is relatively warm already, then a heatmat under a cheap propagator will do the job. Just bear in mind that the power (watts) of your heat element will dictate how much warmer than the ambient temperature your seed trays can get. For example with my 100W propagators you see in the video, I can raise my temperatures at least 10°C above the ambient temperature.

For humidity, I keep a shallow layer of water in the base of the propagator. This does two useful things: it keeps humidity up (which seeds love), and it acts as a kind of thermal buffer that helps spread the heat more evenly.

Some seed trays don’t have grooves underneath though, which caught me out when I started. If they’re sitting flat on a surface with water around them, the water can pool underneath and just stay there. That leads to miserable roots and seedlings that collapse.

I used to raise trays on little spacers, which works but it’s fiddly. The better fix? Put each seed tray on a small drip tray so water can’t get trapped underneath. Simple and it actually works.

Quick Troubleshooting (When Things Go Wrong Starting Chilli Seeds)

Seeds Aren’t Germinating? 

First thing to check is compost temperature. Cold compost is the most common reason seeds just sit there doing nothing. Also make sure your humidity and heat are staying steady inside the propagator. When you check the temperature, don’t rely on your thermostat. Test the temperature at the soil level.

Seedlings Wilting or Getting that Horrible Damp-off Thing? 

This is usually too wet, not enough air, or poor drainage. Make sure water isn’t pooling under flat-bottom trays: raise them or use drip trays. Once seedlings pop up, start giving them fresh air by cracking the lid open.

You Planted Way Too Many Seeds? (We’ve all done it) 

Welcome to the club. Pot up the strongest seedlings first, and thin the rest over time. And maybe, possibly, plan your space and pots before sowing next year? (Who am I kidding, I’ll never learn either.)

Start Chilli Pepper Seeds FAQ

What temperature to germinate superhot chilli peppers? 

Aim for 28°C. Small swings between 27-29°C are completely normal and fine.

What temperature to germinate chilli peppers like Jalapeno or Cayenne? 

28°C works well for these too (I stick to this for all my seeds). However you can get away with lower temperatures, down to around 20°C (68°F), but below this and your germination will be slower.

What temperature is too hot to germinate chilli peppers? 

Try stay below 32°C (90°F), although chilli peppers can survive higher temperatures, its not ideal.

How should I prep the compost? 

Use ordinary compost, sieve it to remove lumps, mix in vermiculite to lighten it and warm it for 24 hours before sowing.

How do I stop drowning the roots? 

Make sure water can drain away from the base. If your trays are flat-bottomed, raise them on spacers or sit them on drip trays.

Do I need special equipment for hundreds of seeds? 

No special compost needed. Organisation matters way more than fancy kit. A warm propagator, clear labels and a simple sowing order make it manageable.

A Quick Word on Seed Quality

Good seeds won’t fix cold compost or overwatering… but they absolutely give you a better start.

Final notes

Winter seed starting is basically this: build a warm, humid bubble and keep it organised.

Warm compost. Steady heat. Decent drainage. Proper labels.

Do that, and you’ll be staring at little green hooks popping up in a few days, grinning like an absolute idiot. Which is exactly the right response, by the way.

Once your chilli seeds have sprouted, you’ll need this article Chilli Seedling Care: Expert Tips

It would be amazing if I could grow everything that is needed for a good kimchi. This year I had to settle for my beautiful Kimchi chillies, and an attempt at growing Napa or Chinese Cabbage. The cabbage growing wasn’t too successful, but here’s the beautiful thing about kimchi: it doesn’t care. Those “reject” cabbages fermented into something tangy, punchy and utterly delicious.

I make kimchi because it’s forgiving, practical, and it uses up what would otherwise go to waste. Plus, once you’ve tasted good homemade fermented kimchi, the shop-bought stuff just doesn’t cut it anymore. The process is straightforward: salt the cabbage, make a chilli paste, stuff the leaves, and let nature do the rest.

What You’ll Need

The basics:

• Cabbage: Chinese or napa cabbage is traditional, but honestly, if your homegrown variety is a bit rough around the edges, that’s absolutely fine. Just trim off the really woody bits.
• Salt: Sea salt, kosher salt, or pickling salt. Avoid iodized table salt if you can; it can interfere with fermentation.
• Chilli powder: Gochugaru (Korean red pepper flakes) is traditional and gives that distinctive flavour. If you can’t get it, use whatever chilli powder you’ve got. Just be aware the flavour profile will be different. And feel free to spice it up with a few superhots too!
• Other veg: Radish, spring onions, carrots.
• Flavour builders: Garlic, ginger, fish sauce (or soy sauce for a vegan version).
• Container: A traditional ongi pot is lovely if you’ve got one, or a good sauerkraut crock with a water moat. But honestly? A BPA-free plastic tub works just fine.

Notes

On salt quantities: This is flexible. I use roughly 50g salt per kg of cabbage, but you can adjust. A little extra is safer than too little (you’ll rinse it anyway).

On chilli heat: Start with 2 cups if you’re unsure. You can always add more next time. Gochugaru has a specific flavour, but homegrown chilli powder works brilliantly too.

Storage: Keeps in the fridge for several months, often up to a year. Flavour becomes stronger and texture softer over time.

Equipment tip: Gloves aren’t optional in my book. Your hands will thank you.

Paste

• 2-3 cups Gochugaru or chilli powder of choice
• 18 cloves Garlic minced
• 1 Onion medium
• 2 tsp Fresh ginger finely grated
• 0.5 cup Fish sauce soy sauce for vegan version
• 1 tsp Thai Shrimp paste if you can get Saeujeot, use that instead (3 tbsp)

Instructions

Prep the cabbage (15 minutes)

• Trim the base where the core is too woody
• Halve the cabbages, small slice at the base to halve once again later
  
• Give a good rinse in cold water
• Remove any seriously damaged outer leaves

Salt the leaves (2 hours)

• Sprinkle sea salt generously between the leaves
  
• Leave cabbage in a large bowl or tray
• Flip or turn the cabbage every 30 minutes
• Salt will draw moisture out (this is what you want)
• When turning, scoop the resulting liquid over the cabbages

Rinse and prepare (10 minutes)

• After 2 hours, rinse cabbage thoroughly under cold water to remove excess salt
• Allow to drain dry
• Leaves should be pliable at this stage

Make the chilli paste (5 minutes)

• In a bowl, combine gochugaru (or chilli powder), minced garlic, grated ginger, and fish sauce
• Taste it (should be punchy, garlicky, with good chilli kick)
• Mix the vegetables into the paste
  

Assemble (20 minutes)

• Put on gloves (seriously, this makes cleanup much easier)
• Split the halves into quarters, using the cut you made earlier
• Take each cabbage leaf and spread paste onto it, down to the base. Coat generously
• Fold the cabbage onto itself making a small pouch
• Pack tightly into your fermentation container (ongi pot, crock, or plastic tub)
• Press down firmly to eliminate air pockets
• Any leftover paste can go on top

Ferment (24-48 hours)

• Leave at room temperature (18-22°C is ideal)
  
• Within 24 hours you should see bubbles forming
• For mild, fresh kimchi: refrigerate after 24 hours
• For tangier, funkier kimchi: leave 48 hours before refrigerating
• Once refrigerated, it will continue to ferment slowly

Fermentation: When to Stop

Leave your kimchi out at room temperature to kick off fermentation. Within 24 hours you should see bubbles and smell that fresh, tangy aroma developing. Now you’ve got choices:

• Mild and fresh? Move it to the fridge after 24 hours.
• Tangier and funkier? Leave it out for up to 48 hours before refrigerating.

Longer fermentation is safe but will change the flavour and texture significantly. I usually go for the 24-48 hour window, then refrigerate.

Storage life: Refrigerated kimchi will keep for months. I’ve had jars going strong after a year, though in practice, most batches disappear far sooner because it’s just too good.

Troubleshooting

No bubbles forming? Check your temperature. Fermentation slows right down in the cold. Move it somewhere warmer for a day or two.

Too salty? Rinse more thoroughly during the initial salt step next time. Most recipes are quite forgiving though.

Surface mould? Rare if everything’s submerged, but if it happens, scrape off the affected bit and make sure everything else is pushed below the liquid. It’s usually fine.

How I Use It

Kimchi isn’t just a side dish (though it’s brilliant with rice and a fried egg for a quick meal). Here’s what I actually do with it:

• Stir-fry chopped kimchi with chicken thighs and rice (simple, fast, flavourful).
• Chop some up and add it to soups or stews to brighten them up.
• Add it to sandwiches for a spicy, tangy kick.
• Eat it straight from the jar while standing by the fridge (don’t pretend you don’t do this).

My Equipment Recommendations

I use an ongi pot when I want to feel traditional, and a small crock for experimental batches. Plastic tubs are my workhorse containers (no fuss, easy to clean, and they work perfectly well).

If you’re planning to ferment lots of things beyond kimchi, investing in a good weighted system can be worth it. But for getting started? Don’t overthink it.

Final Thoughts

The beautiful thing about kimchi is that it rewards you for using what you’ve got. Those imperfect, homegrown cabbages? They’re perfect for this. The process is forgiving enough that you can adapt it to your situation, your ingredients, and your taste preferences.

Stop overthinking it. Make a batch. You’ll learn more from doing it once than reading about it ten times.

Frequently Asked Questions

How long should I ferment before refrigerating?

24 hours gives you mild, fresh kimchi. 48 hours develops more tang. Longer is safe but changes the flavour significantly. Refrigerate when it tastes right to you.

What salt works best?

Sea salt, kosher salt, or pickling salt. Avoid iodized table salt if possible; it can interfere with fermentation.

Can I use imperfect homegrown cabbages?

Absolutely. Trim the woody core, rinse off soil and slug damage, and carry on. The fermentation process is remarkably forgiving.

Do I need special equipment?

No. Traditional pots and crocks are lovely but not essential. BPA-free plastic containers, jars, or anything non-reactive will work fine. Just keep the vegetables packed and submerged.

How long will it keep?

Refrigerated kimchi stays safe and tasty for months. I’ve had batches still going strong after a year, though the flavour becomes stronger and the texture softer over time. Most batches disappear far sooner because it’s delicious.

What if I don’t have gochugaru?

Use whatever chilli powder you’ve got. The flavour will be different from traditional kimchi, but it’ll still ferment beautifully and taste good. I’ve used homegrown chilli powder with excellent results.

Why isn’t my kimchi bubbling?

Temperature is usually the culprit. Fermentation slows down in cold environments. Move it somewhere warmer for a day or two and it should kick off.

Can I add other vegetables?

Definitely. Radish, spring onions, and carrots are traditional additions. Experiment with what you’ve got growing. Just maintain the same salt-and-ferment process.

It is that time of year again. I pick six chilli varieties each season for us to grow together, same plant and same timing, so we can compare progress through the season. If you want a guided way into chilli growing and a community to share results with, grab a kit and grow along.

How I chose this year’s six

I usually start with 12 to 15 candidates and narrow them down based on how they grow, how they taste and how well the seeds germinate. This year I kept a handful of kits aside for Patreons and YouTube members for the first week, just in case we run out of stock!

What is in the 2026 Seed Kit

This year’s selection focuses on flavour, usefulness and a bit of fun. There is something for everyone: mild, medium, hot and completely insane. Below I run through each variety and why I chose it.

CC Fushimi

This is my selectively bred take on the Japanese Fushimi. About four or five years ago I noticed variegation in one of my Fushimi plants: “half-white leaves, crinkle textures and striped pods”. I have been breeding that out for consistency, keeping the beauty while making it more reliable.

The pods are mild and mostly sweet, brilliant in the kitchen. I use them fried or fresh in a stir fry, and they make an excellent filler inside hot sauce. It is one of those plants that is as beautiful as it is useful.

Kimchi pepper

If you love kimchi, you will love this. This is the pepper I use to make the Gochugaru, the red flakes that give kimchi its colour and flavour. I sourced these seeds from a grower in Korea and they dry to a rich, dark red with a truly incredible aroma when drying.

The pods are thin skinned and I dry them slowly to protect the colour and the seeds. The colour is perfect for proper kimchi flakes, and the heat is gentle enough to notice but not overpowering. That balance makes them ideal for kimchi, soups, stews and even sauces. I have already used them in a hot sauce that came out beautifully and I may share that recipe soon.

Chinesicher Runzelhout

The name is a mouthful and roughly means Chinese chilli in German, but it was an experiment that paid off. It turned out to be one of the earliest and most productive plants of the year. The pods are gnarly, crinkled and very attractive.

Heat is mild to medium, about a poblano level. It performed fantastically in my hydro setup and I will try it in soil next season. If you want an easy, early producer that reliably gives loads of pods, this is a really fun plant to grow.

Rocoto Manzano

If you have never grown a capsicum pubescens, this is a special one to try. Look out for black seeds and hairy leaves. The pods are thick and juicy, roughly golf ball size, and begin very sweet and succulent on the palate.

Do not be fooled by that initial sweetness because these rapidly climb to around 150,000 Scoville. They are particularly well suited to cooler climates, like the UK, because they keep producing late into autumn when other plants are fading. If you need a variety that extends your season, these will please you.

CC Chonky Cayenne

This is a new variety I have developed over roughly four years. It started when I noticed some Cayenne plants producing shorter, fatter pods with the same flavour and heat but thicker walls and more flesh. I wanted more usable weight for sauce making, so I selectively bred for higher meat to seed ratio.

The result is the CC Chonky KN: same KN flavour, thicker juicier pods and far better yield for making sauces. It is very productive and performs well in cooler climates. I use KN a lot as a base in sauces, including in my Blazing Buffalo Extreme, and Chonky gives me much more usable flesh per pod.

MA Warthog

This one is for the heat freaks. The MA Warthog comes from Matthew Arthur’s project and is possibly the hottest thing I have ever eaten. It is not fully stable yet and my grow outs showed a lot of variation, but one red plant stood out as the healthiest, most productive and unquestionably the hottest.

I have saved seed from that red variety and that is what is in this year’s seed kit. I also had yellow and peach variants which I will be isolating and stabilising over the next few seasons. There will be a few packets of those variants on the Chili Chump Seeds website as they become available.

The plant itself is a beast. One plant produced four massive trays full of pods. As per the originator’s request, all profits from the warthog seeds will go to children’s charities. For 2026 I want to have some fun: let’s see who can grow the biggest MA Warthog. Tag me or send photos through my website and I will feature the best ones on the channel. If I can find a sponsor, there might even be a prize.

Where to get the Seed Kit

The ChilliChump Seed Kit 2026 is available now at chillichumpseeds.com. Quantities are limited but I have more stock this year than last year, so you should be able to get one. While you are on the site you will also find other seed varieties restocked, including old favourites and some brand new varieties I am excited about.

How to grow along with me

Order a kit, sow the seeds at the same time as me, and we can track progress through the season. Use the same plant choices and timing and share regular updates. Tag me on social or send photos through the website and I will show the best results.

Stay spicy!

Nothing beats homemade chilli jam. It’s cheaper than shop-bought, you control the heat level, and one batch makes enough for months of meals. This recipe works brilliantly with fresh or dried chillies, so you can make it year-round with whatever you’ve got.

Choosing the Right Chillies

The star of any chilli jam is, of course, the chillies. For this recipe, I recommend using cayenne chillies. They’re wonderfully versatile, packing a moderate but enjoyable heat that complements the jam’s sweet and tangy profile without overwhelming your taste buds. Cayenne chillies have just the right balance of spice and flavour, making them perfect for this recipe.

If you want to experiment with heat levels, feel free to add something spicier like habaneros or, if you’re daring, a 7Pot Primo or Primotalii. Just keep in mind that upping the heat means you’ll need to adjust the recipe to maintain the right balance of flavours.

You might notice that some chillies are fresh and ripe while others are dried. That’s perfectly fine and it means you can make this jam year-round. See the Chilli Jam with Dried Chillies variation below for how to adjust quantities.

Gathering Essential Ingredients

Alongside your chillies, you’ll need a few simple but vital ingredients to round out the flavour and texture of the jam:

• Ginger: Peel it easily using a spoon — a tip from one of my subscribers that truly changed the way I prepare ginger. It adds an aromatic warmth that pairs beautifully with the chillies.
• Garlic: Use about 10 cloves, or up to 12 if you like, but don’t go overboard. Too much garlic can overpower the jam, which should lean more towards sweet and spicy rather than savory.
• Jam sugar: This is regular sugar with pectin added, which helps the jam set perfectly. If you have plain sugar, add 15 grams of pectin per kilogram of sugar.
• Citric acid: This helps the pectin set and keeps the jam’s vibrant colour bright and appealing.
• White wine vinegar: I love this for its mild flavour and the lovely golden hue it gives the jam. You can substitute distilled or plain white vinegar, but avoid malt vinegar as it darkens the jam and alters the flavour.
• Salt: Any salt you have on hand will do, but I prefer sea salt for its clean taste.

ChilliChump Chilli Jam Recipe

My foolproof and easy method for crafting a delicious chilli jam that’s bursting with flavour and perfect for a variety of uses.

Course Condiment

Keyword cayenne, chilli jam

Prep Time 10 minutes minutes

Cook Time 40 minutes minutes

Total Time 50 minutes minutes

Equipment

• Jam jars (sterilised)
• Jam funnel
• Large heavy-bottomed pan
• Blender or food processor
• Ladle or spoon

Ingredients

• 1 kg Jam Sugar
• 400 ml White Wine Vinegar
• 300 g Cayenne Chillies
• 120 g Ginger
• 10 cloves Garlic
• 1 tsp Salt
• 0.5 tsp Citric Acid

Instructions

• Sterilise your jars. Wash in hot soapy water, rinse, then place on a baking tray in a 140°C oven for 10 minutes. Keep them warm until you're ready to fill.
• Prep your chillies. Wash thoroughly and remove as many stems as possible, this keeps the colour vibrant and clear.
• Blend the base. Add the chillies, garlic, and ginger to a blender with a small splash of white wine vinegar. Blend to a thick paste. You're not looking for a smooth liquid, keep it chunky enough to coat a spoon.
  
• Combine ingredients. Transfer the paste to a large pan and add the remaining vinegar, jam sugar, citric acid, and salt. Stir well to combine before applying any heat.
• Simmer low and slow. Place the pan on a low heat and stir continuously as the sugar dissolves. Once it becomes liquid, maintain a gentle simmer, bubbles rising slowly, no vigorous boiling, for approximately 40 minutes. Stir regularly to prevent scorching at the bottom.
  
• Test the set. Place a small spoonful onto a cold plate (chilled in the fridge beforehand). Run your finger through it. If the gap holds and doesn't fill back in, the jam is ready. If it floods back, give it a few more minutes and test again.
• Jar the jam. Carefully pour into your warm sterilised jars. Leave to cool at room temperature for 12–24 hours until fully set.
  
• Store. Keep in a cool, dark place for up to a year. Once opened, refrigerate and use within a few weeks.

Preparing and Blending Your Jam Base

Before you start, sterilise your jars: wash in hot soapy water, rinse, then place on a baking tray in a 140°C oven for 10 minutes. Keep them warm until filling.

Wash all your chillies thoroughly to remove any dirt or impurities. Remove as many stems as possible, mainly to keep the jam’s colour vibrant and clear.

Next, blend your chillies, garlic, and ginger into a fine mash. You don’t need a high-powered blender; a basic blender or stick blender will do the job well. Add a splash of vinegar to help the blending process, but be careful not to add too much liquid, especially if your blender isn’t very powerful. You want a thick paste rather than a watery mix.

Cooking Your Chilli Jam to Perfection

Once blended, add the rest of your ingredients: jam sugar, citric acid, salt, and the remaining vinegar. Stir well to combine everything before placing the pot on a gentle heat.

It’s crucial to keep the heat low to avoid burning, especially after adding sugar. Stir continuously to prevent sticking and scorching at the bottom of the pan. You’ll notice the mixture slowly turning into a liquid consistency. Maintain a gentle simmer, bubbles gently rising but no foaming or vigorous boiling, for about 40 minutes. This process reduces moisture and allows the flavours to develop fully.

If you find your jam too thick once set, reduce the amount of pectin next time. Conversely, if it’s too runny, add a little more pectin to achieve your desired consistency.

Setting and Storing Your Chilli Jam

After cooking, remove the jam from the heat and let it cool at room temperature. It will take around 12 to 24 hours to set properly. When done correctly, this chilli jam can last for at least a year when stored in a cool, dark place. If you’re unsure about long-term storage, keep the jam in the fridge and consume it within a few weeks.

How to Test If Your Jam is Ready

To check if your jam has reached the perfect set, pour a small amount while it’s still hot onto a very cold plate (keep the plate in the fridge beforehand). Run your finger through the jam on the plate. If the gap your finger makes doesn’t fill back in, your jam is set and ready to be taken off the heat. If it does fill in, give it a bit more cooking time.

Tasting and Serving Suggestions

Now for the best part: the taste test! Cayenne chillies give this jam a good kick, and the result strikes a perfect balance between sweetness, acidity from the vinegar and heat from the chillies. Unlike overly sweet commercial jams, this one has a complex flavour profile that’s both spicy and tangy.

This chilli jam is incredibly versatile. Use it as a condiment on burgers instead of ketchup or relish for a flavour boost. It’s also fantastic spread on toast or even paired with peanut butter for a unique twist on the classic sandwich.

If you want to skip the cooking and go straight for a bottle, our ready-made chilli jam is available in the ChilliChump shop.

Chilli Jam Variations

Sweet Chilli Jam Variation

For a milder, sweeter jam, closer to the Thai-style sweet chilli sauce you’d find with spring rolls, swap half the chillies for red bell peppers or sweet pointed peppers. This reduces the heat significantly while keeping the colour vibrant and the flavour full. You can also add a tablespoon of fish sauce for extra depth, or a little extra sugar if you want it noticeably sweeter. This version works brilliantly as a dipping sauce or glaze for chicken.

Scotch Bonnet Chilli Jam

Replace the cayenne with scotch bonnets for a fruity, intensely hot jam with that distinctive Caribbean flavour. Scotch bonnets bring a floral, almost tropical note that works beautifully with the sweetness of the jam sugar. Be aware the heat level jumps considerably. Start by using two-thirds scotch bonnet and one-third sweet pepper if you want it manageable, or go full scotch bonnet if you know your audience. This version is excellent with jerk-spiced meats or sharp cheddar on a cracker.

Chilli Jam with Dried Chillies

You don’t need fresh chillies to make a great jam. If you’re working through a dried stash, from your own harvest or shop-bought, use 80g of dried chillies in place of the 300g fresh. Add 220ml of water gradually during blending to bring the mixture up to the right paste consistency. The flavour will be slightly more concentrated and earthy compared to fresh, which works well with smoked or ancho-style chillies. This is a great use for dried whole chillies or anything that’s past its prime for fresh eating.

Frequently Asked Questions

Can I use dried chillies instead of fresh?

Yes. Use about 80g of dried chillies and add 220ml of water gradually while blending to make up the total 300g weight. This makes the recipe workable year-round, even when fresh chillies aren’t available.

What if I want a milder chilli jam?

Mix half the chillies with half red bell or sweet peppers to reduce the heat while maintaining a vibrant colour and flavour. This is also the basis of the sweet chilli jam variation above.

How do I sterilise jars for storing jam?

Wash jars with hot soapy water, rinse well, then heat in the oven at 140°C for 10 minutes. Make sure lids and utensils are sanitised as well before use.

Can I adjust the jam’s thickness?

Yes. If your jam is too thick, use less pectin next time. If it’s too thin, add a little more pectin to help it set better.

How long does homemade chilli jam last?

Stored in sterilised jars in a cool, dark place, it can last up to a year. If you’re unsure, refrigerate and consume within a few weeks for the best flavour and safety.

How many jars does this recipe make?

Approximately 4–6 standard jam jars, depending on jar size and how long you reduce the mixture.

I hope you give this recipe a try and enjoy your homemade chilli jam as much as I do. It’s a fantastic way to add a spicy, sweet, and tangy punch to many dishes. Stay spicy and happy cooking!

Why I Created SpicyIoT

You know how it goes. You start with a simple Arduino project to monitor temperature in your greenhouse. Then you add humidity sensors. Maybe some soil moisture probes. Before you know it, you’re running a dozen different scripts, checking multiple dashboards, and still missing critical alerts because everything’s scattered across different systems.

That was me 8 years ago. My YouTube channel was growing, my commercial growing operation was expanding, and I desperately needed a proper monitoring solution. The enterprise options were overkill (and priced accordingly), whilst the hobby platforms couldn’t handle the reliability I needed for my business.

So I did what any reasonable person would do, spent the next few years building exactly what I needed.

What Makes SpicyIoT Different

I use SpicyIoT every single day to run my actual growing operation, my business. It’s not some theoretical product built in a boardroom. Every feature exists because I needed it, tested it, and refined it in real-world conditions.

The platform handles everything from basic sensor monitoring to complex automation rules. Whether you’re tracking a single temperature sensor in your bedroom or managing an entire commercial operation, it scales with you. Start free with generous limits perfect for hobby projects, then unlock additional features when you need them.

Built for Makers, By a Maker

I’ve kept things simple on purpose. Connect any device that can send web requests – Arduino, ESP32, Raspberry Pi, or even industrial equipment. The RESTful API is straightforward, and I’ve included example code for popular platforms because I remember the frustration of starting from scratch.

Custom dashboards? Drag and drop your widgets however you like. Need alerts? Set up email notifications or webhooks with custom rules. Want to add cameras? Integrate IP cameras or ESP32-CAMs for visual monitoring and time-lapses.

Every feature has been battle-tested in my own setup. If it’s in SpicyIoT, it’s because it proved useful in practice, not because it looked good on a feature list.

No Venture Capital Nonsense

I’ve bootstrapped this entire project. No investors breathing down my neck, no pressure to extract every penny from users. Just solid engineering funded by my YouTube channel and growing business.

This means I can offer a proper free tier that actually stays free. Perfect for weekend projects, students, or anyone just getting started with IoT. When you’re ready for more features, the pricing is reasonable because I’m not trying to achieve a 10x return for Silicon Valley investors.

Your Data, Your Control

One principle I won’t compromise on: your data belongs to you. Export it anytime in CSV or JSON format. No vendor lock-in, no proprietary formats, no holding your information hostage. If you decide SpicyIoT isn’t for you, take your data and leave – no hard feelings.

From Arduino Projects to Commercial Operations

SpicyIoT adapts to whatever you’re building:

• Home Projects: Monitor temperature, humidity, energy usage, or build your own smart home devices
• Growing & Agriculture: Track environmental conditions, automate irrigation, monitor soil moisture and pH levels
• Business & Industrial: Equipment health monitoring, production metrics, environmental compliance
• Education & Research: Collect experimental data, teach IoT concepts, prototype new ideas
• Environmental Monitoring: Weather stations, air quality sensors, water level monitoring

The same platform that started monitoring a few sensors in my greenhouse now manages my entire commercial operation – and it can do the same for you.

Join Me on This Journey

After 8+ years of development and real-world testing, SpicyIoT is ready for you to try. No credit card required, no trial period that expires – just create an account and start monitoring.

Whether you’re a weekend tinkerer or running a business, I built SpicyIoT to grow with your ambitions. The community is already sharing projects, code, and ideas, and I’d love to see what you create with it.
