Flowering Photoperiod
Flowering photoperiod refers to the light-cycle duration that triggers and sustains reproductive development in cannabis plants. Photoperiodic strains require a shift to shorter days (typically 12 hours or less of light) to initiate flowering, whereas autoflowering varieties enter flowering independently of light timing. Breeders document photoperiod sensitivity as a core trait because it directly determines cultivation timing, greenhouse scheduling, and regional viability. Understanding photoperiod genetics helps cultivators plan crop cycles and informs strain selection for indoor versus outdoor production. This trait is inherited and varies significantly across landrace and modern breeding lines.

Breeders select for photoperiod stability and sensitivity to develop regionally adapted cultivars and to create predictable indoor flowering windows. Photoperiod genetics also serve as foundational material in crosses aimed at producing autoflowering hybrids or extending flowering windows.
