Extended Flower Phase
Extended flower phase refers to cannabis cultivars that demonstrate notably prolonged flowering periods, typically requiring 10–14+ weeks from the onset of flower initiation to full maturity. This classification encompasses genetics where the reproductive cycle extends beyond standard photoperiod or autoflowering timelines commonly observed in commercial breeding. Extended flowering is frequently documented in landrace-derived strains, certain tropical sativas, and specific indica-dominant hybrids selected for particular cannabinoid or terpene development windows. Breeders often encounter extended flower phase as an inherited trait when crossing geographically isolated parent lines or when pursuing specific secondary metabolite profiles that require extended maturation periods.

Understanding extended flower phase is critical for cultivation planning and seed selection in breeding programs. Breeders working with this trait must account for extended resource demands, crop timing constraints, and environmental control requirements when incorporating these genetics into commercial or research frameworks.
