Flowering Cycle

Flowering cycle refers to the photoperiod-dependent or genetically-determined timeframe during which a cannabis plant transitions from vegetative growth to reproductive maturity. This trait is primarily governed by genetics rather than volatile organic compounds, though it's often discussed alongside terpene expression timelines. Plants commonly categorized as photoperiodic require specific light-dark ratios to initiate flowering, while autoflowering varieties flower based on age regardless of light conditions. Breeders working in this category track flowering duration—typically 7-12 weeks from flower initiation to harvest readiness—as a key phenotype marker. Understanding flowering cycle genetics is essential for cultivation planning and strain selection in breeding programs.

Breeders select for shortened or extended flowering cycles to optimize yield timing, resource efficiency, and regional growing seasons. Crossing photoperiodic and autoflowering lineages allows creation of hybrid strains with tailored flowering windows, directly influencing commercial viability and breeding outcome predictability.
