Light Cycle Duration
Light cycle duration refers to the photoperiod—the ratio of light to darkness—that cannabis plants require during their growth stages. Most cannabis strains are photoperiod-dependent, meaning flowering is triggered by a shift to shorter days (typically 12 hours light, 12 hours dark). Autoflowering varieties, by contrast, flower based on plant age rather than light duration, making them independent of seasonal or controlled lighting schedules. Understanding light cycle duration is fundamental to cultivation planning, as it directly determines vegetative growth length and flowering timeline. Breeders categorize strains partly by photoperiod sensitivity to help growers optimize yield and crop scheduling.

Breeders select for photoperiod dependency when developing photoperiod-dependent strains, ensuring stable flowering thresholds. Conversely, breeders working with autoflowering genetics prioritize consistent age-to-flower ratios independent of light exposure, a trait derived from Cannabis ruderalis ancestry.
