Flowering Duration Traits

Flowering duration traits describe the time required for cannabis plants to complete their reproductive cycle from the initiation of flower development to harvest-readiness. These characteristics are primarily determined by genetics, with photoperiod-dependent varieties typically flowering over 8-12 weeks, while autoflowering cultivars complete their cycle in 8-10 weeks regardless of light conditions. Breeders have systematically selected for both rapid-finish and extended-bloom phenotypes to suit different cultivation environments and market demands. Duration is influenced by multiple genetic loci and environmental factors including temperature, humidity, and light cycles. Understanding flowering timelines is essential for crop planning, resource allocation, and breeding program development.

Breeders select for flowering duration to create cultivars suited to specific growing seasons, indoor/outdoor environments, and commercial timelines. Traits like early-finish genetics and extended-bloom characteristics are often combined with other desired traits through multi-generational selection to stabilize desired phenotypes.
