Cultivation Duration

Cultivation duration refers to the time required from seed germination to harvest-ready flowers, typically measured in weeks or days. This trait encompasses both vegetative growth phase and flowering time, with significant variation across cannabis genetics. Breeders classify strains into categories like "fast-finishing" (8-9 weeks) and "extended-duration" (10-12+ weeks), each presenting different agronomic tradeoffs. Duration is influenced by photoperiod sensitivity, genetic background, and environmental conditions, making it a key breeding consideration for different production systems. Understanding cultivation duration helps growers plan crop cycles and select genetics suited to their growing environment and timeline constraints.

Breeders working with cultivation duration select for traits that shorten or extend flowering time to match specific cultivation calendars and climate zones. Fast-finishing genetics are often valued in regions with shorter growing seasons or for high-turnover indoor operations, while longer-duration cultivars may develop more complex terpene profiles under extended photoperiods.
