Photoperiod Plants
Photoperiod plants are cannabis cultivars whose flowering is regulated by day length rather than age. These plants typically require a shift to shorter days (usually 12 hours of light or less) to initiate and complete the flowering cycle. Photoperiod genetics are foundational in breeding programs because they allow breeders to maintain vegetative growth indefinitely under longer photoperiods, creating extended selection windows. This trait contrasts with autoflowering genetics, which flower based on age regardless of light schedule. Photoperiod cultivars dominate both heritage landraces and modern breeding work, making photoperiod sensitivity a primary consideration in strain development and lineage documentation.

Breeders working with photoperiod plants can control timing of flowering through light manipulation, enabling selective breeding across multiple generations within a single calendar year under controlled conditions. This photoperiod responsiveness is critical for maintaining true-breeding lines and developing stable hybrid crosses before release.
