Long Photoperiod Types
Long photoperiod types refer to cannabis plants that require extended daily light exposure—typically 14–16+ hours—to initiate and complete flowering. These genetics are commonly associated with equatorial or subtropical origin regions where day length remains relatively constant year-round. Breeders distinguish long photoperiod varieties from short photoperiod (autoflowering) and standard short-day types, as they demand precise light scheduling in controlled environments. Lineage records frequently report long photoperiod traits in pure sativa and sativa-dominant crosses, reflecting their natural geographic adaptation. Understanding photoperiod requirements is essential for cultivation planning, as inadequate light duration can delay or prevent flowering entirely.

Breeders working in photoperiod-dependent genetics use long photoperiod types to introduce vigor, extended vegetative phases, and sativa-characteristic growth patterns into hybrid programs. Precise photoperiod control enables selection for desired morphology, potency, and terpene expression before committing plants to flower.
