Growth Stages

1

Seedling

2-3 weeks

Keep soil consistently moist but not waterlogged. Provide bright light (grow lights recommended). Maintain 70-75°F temperature.

2

Vegetative

4-6 weeks

Plant develops multiple stems and increasingly dense foliage; grows bushy

Pinch back growing tips to encourage branching. Fertilize weekly with balanced fertilizer. Ensure adequate light to prevent leggy growth.

Small purple or white flowers appear in clusters along stems

Maintain consistent watering and fertilize with balanced formula. Light pollination may occur naturally or with hand pollination.

4

Fruiting

4-6 weeks

Small round fruits develop, showing distinctive red-and-white striped pattern as they mature

Reduce nitrogen fertilizer; switch to higher phosphorus formula to support fruiting. Continue consistent watering.
