Days To Flower
Days to Flower (DTF) refers to the number of calendar days required for a cannabis plant to transition from vegetative growth to mature flowering stage under standard photoperiod conditions—typically measured from the onset of 12/12 light/dark cycle to harvest-readiness. This trait is primarily determined by genetics, though environmental factors including light quality, temperature stability, and nutrient availability can modulate the timeline. Breeding programs track DTF as a core agronomic marker because it directly impacts cultivation cycles, resource allocation, and commercial viability. Plants commonly range from 45–90+ days to flower depending on strain family and phenotypic expression. Understanding DTF classification helps growers and breeders optimize production schedules and select genetics suited to specific growing environments and regional constraints.

Breeders systematize DTF data across crosses to develop photoperiod-stable lines and to create breeding populations with predictable flowering windows. Selection for accelerated or extended flowering timelines enables development of cultivars optimized for different climates, indoor facility designs, and commercial harvest calendars.
