Dormancy Extension

Dormancy extension refers to the prolonged vegetative state some cannabis genetics maintain before naturally triggering flowering cycles. This trait is influenced by photoperiod sensitivity and genetics inherited from parent lines, with some cultivars bred to delay reproductive maturation under standard light schedules. Breeders working with this characteristic often select from landraces or stable lines known for extended growth phases before flowering initiation. Dormancy extension is distinct from photoperiod-dependent flowering and is commonly observed in certain sativa-dominant lineages and some hybrid crosses designed for extended veg cycles.

Breeders utilize dormancy extension genetics when developing cultivars intended for longer vegetative growth periods, which can support larger plant architecture and extended canopy development. Selection for this trait requires controlled environment monitoring and multiple generation testing to isolate stable dormancy patterns.
