Long Day Photoperiod Response
Long Day Photoperiod Response describes cannabis plants that flower when exposed to extended periods of light—typically 14+ hours daily. This trait is relatively uncommon in modern cannabis cultivars, as most commercial varieties are selected for short-day (long-night) flowering. Plants exhibiting long-day photoperiod sensitivity often derive from landrace or wild-type genetics adapted to equatorial or high-latitude environments. Understanding this response is primarily relevant to breeders working with diverse genetic backgrounds or attempting to preserve heritage genetics.

Breeders may deliberately select for long-day photoperiod traits when developing cultivars for specific geographic regions or when crossbreeding with wild or landrace populations. This trait is useful for research into photoperiodic control mechanisms and for creating cultivars suited to non-traditional growing seasons or northern hemisphere outdoor cultivation.
