Light for pepper plants: sunny window, artificial lights, or full sun
The short version: Peppers want 6-8 hours of direct sun a day, or 12-16 hours under artificial lights indoors. A south-facing window covers most varieties with no equipment at all. And since every plant we sell grew up inside under controlled light, ease it into direct sun over about a week before you leave it out there.
The numbers, up front
Peppers need a minimum of 6-8 hours of direct sunlight a day. Under artificial lights indoors, the number is 12-16 hours. Miss the minimum and you get a leggy plant that makes leaves and no fruit.
Past the minimum, the rule is short: more sun, more peppers. Everything below is just different ways of hitting the number.
A sunny window
A south-facing window gives 6 or more hours of direct sun, which is the sweet spot for most varieties. It's the classic setup and needs no equipment at all. Compact, milder varieties do especially well there.
Two habits make it work: rotate the plant weekly so it grows evenly, and keep it away from drafty windows in winter. Peppers like the warmth of your house.
If all you have is bright indirect light on a kitchen counter, small ornamental varieties will still do fine. They won't set much fruit, but they look the part.
Artificial lights
No good window, no problem. A basic full-spectrum LED panel running 12-16 hours a day opens up any room in the house. Peppers are day-neutral, so there's no special light schedule to get right.
You don't need anything fancy; a cheap panel works fine. It's also how we do it ourselves. Every plant we sell is grown under 16 hours of light in a climate-controlled nursery, all year.
Artificial light also solves a climate problem. If your summers run cool, superhots won't fully ripen outside. A Reaper under a lamp doesn't know what your summer is doing.
Full sun outside
Once a plant is acclimated, give it 6-8 or more hours of direct sun a day. Full sun is where growth and fruit production peak, and it's where the big harvests come from.
Heat is the caveat. Once summer highs push past 100°F, shade cloth earns its keep — above 104°F, peppers start dropping blossoms. Microclimates matter more than people expect, too: a south-facing wall adds 5-10°F of effective warmth to whatever sits in front of it, which is free heat in a cooler climate.
Easing a plant into direct sun
Every plant we ship grew up indoors under controlled light. Put it straight into full sun and the leaves can scorch: white, bleached, papery patches. Ease it in over about a week instead. Days 1-2, give it 1-2 hours of morning sun or bright shade. Days 3-4, stretch to 3-4 hours with some gentle direct sun. Days 5-6, go 5-6 hours with more midday exposure. Day 7 and on, it lives outside.
That's a guideline, not a contract. Watch the plant, not the calendar. If leaves start looking stressed or bleached, pull it back into shade and slow down. A little wind along the way is fine — it builds a thicker, stronger stem.
The same logic applies on delivery day. After a few days in a dark box, start the plant by a bright window or under an artificial light, then work up to stronger light over the following days. A few dropped leaves after transit is normal, not damage. It recovers once it's back in light.
Winter doesn't end it
Peppers are perennials. Bring the plant inside before a hard freeze, park it by a bright window or under a light, and it keeps producing through winter.
The one group that wants extra attention in cooler months is the chinense family: ghost peppers, Carolina Reapers, habaneros. They prefer high heat, so give them the warmest bright spot you have.
