Seedling
2-3 weeksSmall green cotyledons emerge and develop first true leaves; plant is delicate and compact
Keep soil moist but not soggy. Provide bright light (14-16 hours). Maintain 70-75°F temperature. Thin weak seedlings.
Vegetative
3-4 weeks before flowering beginsPlant develops bushy branching structure with dark green foliage; no flowers yet
Harden off transplants by gradually exposing to outdoor conditions. Support with stakes if needed. Monitor for leggy growth and pinch back if necessary.
Flowering
2-3 weeks overlapping with fruitingSmall white flowers appear at branch tips in clusters; plant continues to grow and branch
Maintain consistent watering and temperatures. Avoid excessive nitrogen fertilizer (promotes foliage over fruit). Hand-pollinate if needed indoors. Reduce watering slightly to encourage fruiting.
Fruiting
3-4 weeks per fruit cycleFruit sets and develops as small green peppers; peppers gradually enlarge and change color to yellow-orange
Maintain steady moisture and warmth (70-80°F optimal). Apply balanced or phosphorus-rich fertilizer every 2-3 weeks. Prune excessive foliage shading fruit.
Harvest
Throughout growing season; 8-12 weeks in optimal conditionsPeppers reach full size and color; plant produces multiple flushes of fruit throughout season
Harvest regularly to encourage more flowering. Use scissors or pruners to avoid damaging branches. Continue watering and feeding for continuous production.

Harvest Tips
Harvest peppers when they reach full size and desired color (yellow-orange for Sweet Lightning). Use pruners or scissors to cut peppers cleanly from the plant, leaving stems intact. Harvesting green peppers will allow the plant to focus energy on additional fruit. Continue harvesting throughout the season (typically June-October in temperate zones) to encourage continuous production. Peppers can be harvested slightly early for green stage or left on plant to fully ripen for sweeter flavor and full color development.
