Seasonal Cycling
Seasonal cycling refers to cannabis plants that rely on photoperiod changes to transition from vegetative to flowering stages, typically triggered by shortening day length. These photoperiod-dependent cultivars contrast with autoflowering varieties, which flower based on age rather than light schedules. Seasonal cycling strains dominate outdoor cultivation in most temperate climates and form the foundation of traditional breeding work. Understanding seasonal cycling is essential for breeders working with classic landrace genetics and establishing stable photoperiod-sensitive lines. Indoor growers managing these cultivars must simulate natural light cycles or manually adjust photoperiod to induce and control flowering timing.

Breeders working with seasonal cycling plants can extend selection periods and conduct multiple generations annually through light manipulation. This classification enables preservation of photoperiod-dependent traits from heirloom and regional cultivars.
