Crop Duration

Crop Duration refers to the total time required from seed germination (or clone rooting) to harvest-ready maturity. This timeline varies significantly across cannabis genetics, ranging from fast-finishing cultivars at 7–8 weeks to extended-cycle strains requiring 12+ weeks of flowering. Duration is influenced by both genetic programming and environmental factors including light cycles, temperature, and nutrient availability. Breeders classify plants into categories like "auto-flowering" (fixed duration regardless of photoperiod), "photoperiodic" (dependent on light cycle length), and fast vs. standard vs. extended phenotypes. Understanding crop duration is essential for cultivation planning, resource allocation, and regional legal compliance in jurisdictions with seasonal restrictions.

Breeders select for crop duration to create varieties suited to specific growing environments—short cycles for indoor operations and limited outdoor seasons, longer cycles for maximum cannabinoid and terpene development. Duration genetics are often stacked with other traits like yield potential or disease resistance to create commercial cultivars.
