Bell peppers in greenhouses
Steady, predictable and strongly demanded at retail — greenhouse peppers reward patient climate management with consistent yields across four color stages, each with its own market position.
Four colors, one crop
Green, red, yellow and orange greenhouse peppers are stages and selections of the same crop — green is harvested earlier, while red, yellow and orange ripen longer on the plant for sweeter flavor and premium pricing.
- Green — the earliest harvest and fastest turnover; a foodservice and value-retail staple.
- Red — fully ripened and sweetest of the classics; the volume leader at retail.
- Yellow — bright, mild and sweet; a fixture of the mixed three-pack.
- Orange — the newest of the four at retail, prized for color mixes and snacking.
Indicative yields
Derived from GrowPro model yield data (hydroponic cultivation, unlit — peppers are typically grown without supplemental lighting):
| Color | Yield |
|---|---|
| Red | ≈ 27 kg/m²/yr |
| Yellow | ≈ 26 kg/m²/yr |
| Green | ≈ 25 kg/m²/yr |
| Orange | ≈ 23 kg/m²/yr |
Actual results depend on climate, variety and cultivation strategy.
Nutritional value (per 100 g)
Ripening stage shows in the numbers — the longer a pepper stays on the plant, the more vitamin C and carotenoids it builds. Indicative values per 100 g:
| Color | Calories | Vitamin C | Vitamin A | Potassium |
|---|---|---|---|---|
| Green | 20 kcal | 80.4 mg | 370 IU | 175 mg |
| Red | 31 kcal | 127.7 mg | 3,131 IU | 211 mg |
| Yellow | 27 kcal | 183.5 mg | 200 IU | 212 mg |
| Orange | 30 kcal | 130.0 mg | 2,500 IU | 210 mg |
Greenhouse configuration
Greenhouse peppers are the marathon runners of the greenhouse: one long crop cycle per year with steady picking across the season. They favor stable temperatures and careful humidity control, making a well-screened, well-heated greenhouse essential. The Expert series covers pepper production up to 2 acres; the Plus series suits large-scale and warmer-climate projects. Labor is lower than tomatoes — no truss work — with harvest concentrated on color-ready fruit.
Frequently asked questions
Why do red peppers cost more than green?
Red, yellow and orange peppers stay on the plant weeks longer to ripen fully, occupying greenhouse space longer — green peppers are the same crop harvested earlier.
What yields can I expect?
Roughly 23–27 kg/m²/year in a GrowPro greenhouse depending on color, with red typically the highest at ≈ 27 kg/m².
Do peppers need growlights?
Usually not — commercial pepper production typically runs unlit on a single long annual crop cycle.
Which greenhouse model fits pepper production?
GrowPro Expert up to 2 acres; GrowPro Plus for scale and for climates that need extra screening or cooling.
