Light Cycle Requirements
Light cycle requirements refer to the photoperiod needs of cannabis plants during cultivation—specifically, the ratio of light to darkness required to trigger flowering in photoperiodic varieties. Most traditional cannabis strains are short-day plants, requiring 12 hours of uninterrupted darkness to initiate and sustain flower production, while vegetative growth typically occurs under 18+ hours of light. Autoflowering genetics, conversely, flower based on plant age rather than photoperiod, eliminating strict light-cycle dependency. Understanding a strain's light-cycle classification is foundational for indoor cultivation design, outdoor planting timing, and breeding programs targeting photoperiodic or autonomous flowering traits. Breeders document photoperiod sensitivity when developing new lines, as light-cycle stability affects yield predictability and crop scheduling across growing en

Breeders select and stabilize light-cycle traits to produce reliable flowering behavior in target markets—short-day photoperiodic varieties for controlled indoor production, and photoperiod-insensitive autoflowers for rapid turnover and outdoor flexibility. Crossing photoperiodic and autoflowering parents has become standard practice for developing hybrid genetics with customized flowering trigger
