Short Day Sensitive
Short Day Sensitive refers to cannabis plants that initiate flowering in response to shortened daylight hours, typically when photoperiod drops below 12-14 hours of light per day. This trait is common in photoperiodic cannabis varieties, particularly landraces and traditional breeding lines adapted to natural seasonal cycles. Short Day Sensitive plants require deliberate light cycle manipulation in controlled environments to flower reliably indoors. Breeders working with photoperiodic genetics must account for strict light schedules during breeding projects. This classification contrasts with autoflowering varieties, which flower based on age rather than day length.

Photoperiodic sensitivity is a fundamental trait in breeding programs focused on producing stable photoperiodic lines or maintaining genetic diversity. Breeders select for consistent short-day response timing to ensure predictable flowering windows and crop planning reliability.
