Photoperiodism
Photoperiodism is not a terpene, but rather a critical biological mechanism governing cannabis flowering cycles based on light duration. Traditional photoperiodic cannabis strains initiate flowering when daily light periods fall below a threshold—typically 12-14 hours—triggering hormonal shifts that redirect plant energy from vegetative growth to flower production. This trait is foundational in breeding programs and cultivation strategies worldwide. Understanding photoperiodic responses helps breeders develop stable cultivars suited to specific growing regions and seasons. The trait contrasts sharply with autoflowering genetics, which flower based on plant age rather than light schedules.

Breeders leverage photoperiodic traits to create regionally adapted cultivars and maintain predictable crop cycles in controlled environments. Stabilizing photoperiodic thresholds in breeding lines allows for consistent flowering windows across generations.
