Seedling
2-3 weeksTiny seedlings with cotyledons emerge and develop true leaves. Plants are delicate and light green.
Maintain 70-80°F soil temperature. Provide 14-16 hours of grow light daily. Keep soil consistently moist but not waterlogged. Thin to strongest seedlings.
Vegetative
4-6 weeksPlant develops multiple stems and dark green leaves. Height reaches 6-12 inches with bushy growth habit.
Maintain warm temperatures (70-85°F). Gradually harden off before transplanting outdoors. Apply balanced fertilizer every 2 weeks. Pinch main stem at 6 inches to encourage branching.
Flowering
3-4 weeksSmall white or pale flowers appear at leaf axils. Plant may reach 12-18 inches tall with dense foliage.

Fruiting
2-3 weeks (green stage)Green peppers develop rapidly at flower sites. Peppers gradually enlarge to 2-3 inches long and become thick-walled.
Maintain consistent deep watering. Switch to lower nitrogen, higher potassium fertilizer. Support heavy fruit loads with stakes if needed. Harvest green peppers or allow ripening to red.
Maturation & Harvest
2-4 weeks per flush; season extends until frostPeppers turn brilliant red, becoming sweeter and more pungent. Walls thicken and flavor intensifies.

Harvest Tips
Harvest green peppers 60-75 days after transplant for milder heat; allow 90+ days for full red color and maximum heat (100,000-150,000 Scoville units). Use sharp pruners to cut peppers at the stem rather than pulling. Pick regularly to stimulate continued flowering. Peppers ripen progressively on the plant; harvest in morning when skin is firm.
