Photoperiod Genetics
Photoperiod genetics refers to cannabis cultivars whose flowering is triggered by changes in day length, typically initiating bloom when exposed to 12 hours or less of light daily. This trait contrasts with autoflowering varieties, which flower based on plant age rather than light cycles. Photoperiod plants are commonly associated with longer vegetative phases, allowing extended growth and larger yields under controlled conditions. Breeders working in this category value photoperiod genetics for their stability, vigor, and the flexibility to manipulate crop timing through light management. Many classic and heirloom lineages are photoperiod-dependent, making this genetics family foundational to modern breeding programs.

Breeders select photoperiod genetics to maintain control over plant maturation, extend selection windows, and preserve strain characteristics across generations. This predictability is essential for commercial cultivation, breeding work, and creating F1 hybrids with consistent flowering patterns.
