Flowering Cycle 14 16 Weeks

The 14–16 week flowering cycle describes cannabis cultivars that require approximately three to four months from first flower initiation to mature seed or resin production. This extended timeline is commonly associated with sativa-dominant lineages, equatorial and subtropical landraces, and complex hybrid crosses that inherit longer day-length sensitivity. Breeders working in tropical and outdoor breeding programs frequently encounter these cycles as a natural consequence of genetic architecture shaped by geographic origin. Plants in this category often exhibit extended branching, larger final stature, and protracted cannabinoid and terpene development compared to faster-finishing cultivars.

Breeders selecting for this flowering duration typically prioritize cultivars suited to long-season outdoor environments, equatorial photoperiods, or controlled environments where extended cultivation timelines are viable. This trait is often retained intentionally when preserving landraces or developing photoperiod-sensitive hybrid lines valued for specific yield profiles or secondary metabolite
