Light Cycle Dependency
Light cycle dependency describes a plant's responsiveness to photoperiod—the ratio of light to darkness—in regulating flowering timing and development. Cannabis is a short-day plant, typically requiring ~12 hours of uninterrupted darkness to initiate and sustain the flowering phase, though individual cultivars show variation in sensitivity thresholds. Some photoperiod-dependent strains flower reliably only when day length drops below specific hour counts, while others display earlier or delayed responses. This trait is distinct from autoflowering genetics, which transition to bloom based on age rather than light schedule. Understanding light cycle dependency is essential for indoor cultivation planning, outdoor seasonal timing, and breeding programs selecting for consistent flowering windows.

Breeders document photoperiod sensitivity to create predictable crop scheduling and to stabilize flowering duration across generations. Crossing photoperiod-dependent parents with known critical day lengths helps establish reliable cultivar performance in controlled and seasonal environments.
