Life Cycle Duration

Life cycle duration refers to the total time required for a cannabis plant to complete its growth from seed germination through harvest-ready maturity. This span typically ranges from 8 to 16+ weeks depending on genetics, photoperiod sensitivity, and environmental conditions. Breeders classify plants into categories like "fast-finishing" (8–10 weeks), "standard" (10–12 weeks), and "extended" (12+ weeks) to help growers match cultivars to their climate and season. Life cycle duration is a primary selection criterion in breeding programs, as it directly influences cultivation feasibility, resource efficiency, and regional viability. Understanding a strain's lifecycle helps breeders optimize for both indoor controlled environments and outdoor seasonal windows.

Breeders actively select for life cycle duration to create cultivars suited to specific growing regions and farming systems. Shorter-finishing genetics are particularly valuable for northern climates, outdoor grows with condensed seasons, and high-turnover indoor operations, making them frequent targets in modern breeding programs.
