Life Cycle Duration

Life cycle duration refers to the total time required for a cannabis plant to complete its development from seed germination through harvest-ready maturity. This classification encompasses photoperiod-dependent plants (requiring specific light cycles to flower), autoflowering varieties (flowering based on age rather than light), and fast-finishing photoperiod strains bred for accelerated completion. Breeders document lifecycle duration to help cultivators plan crop schedules, manage space efficiently, and predict yield windows. Duration varies significantly—from 8-10 weeks for fast autos to 12-16+ weeks for extended photoperiod cultivars. Understanding lifecycle timing is essential for both outdoor seasonal planning and indoor cultivation strategy.

Breeders select and stabilize for lifecycle duration to create varieties suited to specific growing environments and market demand. Short-cycle genetics enable multiple harvests per season outdoors in temperate zones, while extended-cycle strains often develop more complex secondary metabolite profiles during longer vegetative and flowering phases.
