Light Dependent Flowering

Light-dependent flowering is not a terpene, but rather a photoperiodic trait describing how cannabis plants initiate bloom cycles in response to light duration. Traditional photoperiodic varieties require shortening day length (typically 12 hours or less of light) to trigger the flowering transition, a mechanism evolved in wild cannabis populations across diverse latitudes. This contrasts with autoflowering genetics, which flower based on plant age rather than light cycles. Understanding light dependency is fundamental to cultivation planning, as it directly determines grow room lighting schedules and overall crop timing. Breeders working with photoperiodic lines maintain careful light documentation to preserve this trait's stability across generations.

Breeders select for consistent light-dependency thresholds when developing photoperiodic cultivars, ensuring reliable flowering responses in commercial and research settings. Stabilizing photoperiodic traits requires controlled lighting environments across multiple generations to maintain predictable flowering windows.
