The Best Peppers to Grow Indoors
By Debra Austin
Most nurseries stop selling pepper plants in June. We never start, because we never stop: every plant we sell grows indoors under light, so we ship live plants in October, in December and in February. No yard, no season and no frost date required. Here is what to grow inside, and how to keep it going.
Our top 10 peppers to grow indoors
Pick a compact pepper, give it real light, and don't overwater it. These fruit best for us indoors, ranked from easiest to most demanding. A small, compact pepper under a decent light makes a better first grow than a famous superhot in a dim window.
What we'd skip for a first indoor grow: full-size bells and tall baccatums like Sugar Rush Peach. Big pods are energy sinks in weak light, and baccatums can top 6 feet. The same goes for a superhot as your first indoor plant: grow one easier chinense first.
Availability changes weekly. Each plant's page shows whether it's ready to ship.
What Are Indoor Peppers?
Indoor peppers are exactly what they sound like: pepper plants grown entirely inside your home. Not a different species, not a special hybrid. They're the same Capsicum varieties you'd grow outside, just adapted to container life with a little help from you.
The best indoor varieties tend to be compact (under 2 feet), don't need a ton of root space, and fruit reliably without outdoor pollinators. Think Thai chilies on a sunny windowsill, a Shishito plant under an artificial light, or a Bolivian Rainbow as a living centerpiece that also makes dinner better.
Every plant we ship is already growing, with its root ball wrapped in a moisture-retaining bag. Get it into a container on a windowsill (or something bigger) within a day or two, and it's ready to go.
Pro Tip
South-facing windows give 6+ hours of direct sun, the sweet spot for most pepper varieties.
Where Can You Grow Them?
How to Grow Peppers Indoors
Varieties That Thrive Indoors
C. annuum, C. baccatum, and C. pubescens varieties from our current shop, chosen because they are compact, productive, and actually suited to life indoors.
Every one of these is a plant we actually grow, not a catalogue entry. Each ships potted and ready to move up into something bigger.
Take It Further: Bonchi
Once you've got indoor peppers dialed in, the next level is bonchi, bonsai chile peppers. You prune and train your pepper plant into a miniature tree form. It's part art, part horticulture, and the results are stunning. Plants can live for years this way.
The best resource out there is the Bonchi Booklet from Fatalii Seeds, the most comprehensive guide ever written on the subject. If you're serious about indoor peppers, it's worth a look.

Mix and match any varieties. Build your indoor collection, pick your favorites, and we'll ship them to your door with care.
How much light do indoor pepper plants need?
Peppers need 6-8 hours of direct sunlight minimum, or 14-16 hours under a bright lamp. Without enough light, you'll get leggy plants and no fruit. A full-spectrum white LED on a timer works fine. You do not need anything fancy. Most indoor growers overestimate window light. Your eyes adjust, but a pepper plant doesn't, so even a sunny window benefits from a light in winter.
What soil should I use for indoor pepper plants?
Use a well-draining container mix, never garden soil. Something with perlite or pumice mixed in is ideal. Nothing ships in a pot. We grow in pots, take the pot off, and bag the root ball with its potting mix still around it, so container it up when it lands. When you transplant, 2 to 3 gallons suits compact indoor varieties, and 5 to 7 gallons gives bigger plants a better buffer for water and food.
How often should I water an indoor pepper plant?
Stick your finger an inch into the soil. Dry? Water it. Damp? Leave it alone. Overwatering kills more indoor peppers than anything else. Let the soil dry out between waterings and make sure your container has drainage holes.
What temperature do indoor pepper plants need?
Peppers love warmth. 65-85°F is the sweet spot. They'll survive cooler temps but growth slows way down below 60°F. Keep them away from drafty windows in winter. Most houses are already warm enough, so this is usually the easy part.
Do indoor pepper plants need pollinating?
No bees inside? No problem. When flowers appear, give the plant a gentle shake, or use a small paintbrush to transfer pollen between flowers. You can also point a small fan at them, because the airflow helps. Do this every few days and you'll get fruit.
How do I fertilise an indoor pepper plant?
Once your plant is established, feed it every 2 weeks with a balanced liquid fertilizer (something like 5-5-5 or a tomato/pepper formula). During flowering and fruiting, switch to something higher in phosphorus and potassium to boost production.
