Autoflowering
Category: Cultivation · Level: Intermediate
Autoflowering cannabis plants begin to flower based on age rather than changes in light cycle, derived from Cannabis ruderalis genetics.
Autoflowering cannabis plants are a genetic category that transitions from vegetative growth to flowering automatically after a set period of time (typically 2–4 weeks), regardless of photoperiod changes. This trait is derived from Cannabis ruderalis, a subspecies native to Central Asia and Russia that evolved to flower quickly in short summers. Autoflowering cultivars typically have shorter life cycles (8–12 weeks seed to harvest), smaller plant size, and are well-suited for outdoor cultivation at northern latitudes. Modern auto cultivars have been bred to produce competitive cannabinoid profiles compared to photoperiod strains, driving significant commercial adoption.
