Flowering Dependence
Flowering dependence refers to cannabis plants whose transition to reproductive phase is governed primarily by photoperiod—the ratio of light to darkness in a 24-hour cycle. These plants typically require specific day-length triggers (commonly 12/12 light/dark cycles) to initiate flowering, rather than relying on age or other environmental cues. Photoperiod-dependent varieties are contrasted with autoflowering cultivars, which flower based on developmental age. This trait is foundational to traditional breeding programs and remains prevalent in many landrace and F1 hybrid lineages. Understanding flowering dependence is essential for cultivation planning, breeding timelines, and genetic preservation work.

Breeders working with photoperiod-dependent lines use controlled light schedules to manage generation cycles, extend vegetative periods for clonal selection, and maintain stable flowering windows across seed runs. This trait allows reproducible multi-generational work and precise hybridization timing in breeding programs.
