Bloom Cycle Length
Bloom cycle length refers to the number of days a cannabis plant requires to complete flowering from the initiation of the photoperiod until harvest-ready maturity. This trait is primarily determined by genetic background, with photoperiod-sensitive varieties typically flowering within 8–12 weeks under standard 12/12 light cycles, while autoflowering genetics often complete their cycle in 8–10 weeks regardless of light schedule. Breeders classify cultivars along this spectrum to match cultivation environments, regional growing seasons, and production timelines. Understanding bloom cycle length is essential for planning crop rotations, managing indoor facility capacity, and optimizing outdoor harvest windows. Lineage records frequently report bloom time as a core breeding descriptor, as it directly influences yield planning and resource allocation.

Breeders select for bloom cycle length to create cultivars suited to specific production models—shorter cycles enable multiple harvests annually in controlled environments, while longer cycles may allow for greater cannabinoid and terpene maturation. Cross-breeding with photoperiod-independent genetics (autoflowering lines) has expanded the range of flowering durations available in modern breeding
