Short Day Breeding
Short day breeding refers to photoperiod-sensitive cultivation practices where cannabis plants are exposed to extended dark periods to trigger flowering. This technique is foundational in traditional cannabis horticulture and remains relevant for seed production and strain stabilization. Breeders working with photoperiod-dependent genetics use controlled light cycles—typically 12 hours light and 12 hours dark—to reliably induce flowering at desired times. The method contrasts with autoflowering genetics, which flower based on plant age rather than light duration. Understanding short day mechanics is essential for anyone managing seed lines, preserving heritage genetics, or conducting controlled crosses.

Professional breeders employ short day cycles to maintain predictable flowering windows, ensure stable seed production, and preserve photoperiod-dependent landrace genetics. Controlled photoperiod management also allows breeders to stagger generations and run multiple crop cycles annually in controlled environments.
