Seed To Harvest Time

Seed-to-harvest time refers to the total calendar duration from germination through final flower maturity and harvest. This trait encompasses both vegetative growth phase and flowering duration, varying significantly across cannabis genetics—from rapid 8-week total cycles in some photoperiod varieties to 10-16+ weeks in others. Autoflowering lines typically complete their full lifecycle in 8-10 weeks regardless of light schedule, while photoperiod strains depend on light manipulation to transition from vegetative to flowering. Seed-to-harvest time is influenced by genetics, environmental conditions (temperature, humidity, light), and cultivation technique. Understanding this trait is essential for crop planning, resource allocation, and matching cultivars to growing constraints.

Breeders select for seed-to-harvest duration to develop cultivars suited to specific climates, indoor facility turnaround requirements, and outdoor seasonal windows. Shorter cycles enable multiple harvests per year indoors, while extended flowering times may concentrate secondary metabolites in some lineages.
