Photoperiod Plant
Photoperiod plants are cannabis cultivars whose flowering is triggered by changes in day length, typically requiring a shift to shorter days (longer nights) to initiate reproductive cycles. In nature, this mechanism allows plants to flower when seasonal light patterns signal appropriate breeding conditions. Photoperiod varieties are distinguished from autoflowering types, which flower based on age rather than light schedules. Breeders working with photoperiod genetics maintain precise light cycles in controlled environments to manage growth and flowering phases predictably. The photoperiod classification encompasses the vast majority of traditional cannabis cultivars, including many landrace and heirloom lines.

Photoperiod genetics allow breeders to extend vegetative phases for larger plant development, clone selection, and controlled cross-breeding. This trait is foundational to most commercial breeding programs and research facilities, where 12/12 light cycles standardize flowering timelines across multiple genotypes.
