Late Flowering

Late flowering refers to cannabis cultivars that typically require 9-12+ weeks to reach harvest maturity, compared to standard 8-week photoperiod strains. This classification often correlates with longer-day photoperiod requirements and is frequently observed in landrace genetics and their descendants, particularly from equatorial and subtropical regions where natural seasons extend flowering cycles. Breeders working with late-flowering material often document extended bud development phases and potentially higher terpene complexity due to prolonged maturation windows. The trait appears heritable and can be maintained or crossed into other lineages, though indoor cultivation timelines and environmental control become significant management factors.

Breeders select late-flowering genetics to extend bud maturation and potentially develop more complex terpene profiles, though this requires longer crop cycles and increased resource commitment. The trait is sometimes crossed into faster lines to balance yield timing with desired cannabinoid or terpene expression.
