Photoperiod Genetics
Photoperiod genetics refers to the genetic mechanisms in cannabis that regulate flowering timing based on light cycle duration. Plants carrying photoperiod-dependent traits require specific light-to-dark ratios (typically 12/12 hours) to transition from vegetative growth to flowering, distinguishing them from autoflowering varieties. This trait is controlled by multiple genes that detect and respond to day length, making it fundamental to traditional breeding programs. Photoperiod genetics are essential in controlled indoor cultivation and form the backbone of most heritage and modern cultivar development. Understanding photoperiod expression helps breeders select for stability, predictability, and consistency across generations.

Breeders working with photoperiod genetics can manipulate flowering timing and extend vegetative growth periods to develop larger plants with more branching. This control enables targeted crossing schedules, extended mother plant maintenance, and careful phenotype evaluation before final selection.
