Strain type

Autoflower cannabis strains

Autoflowering strains carry ruderalis genetics from cold, short-season regions of Russia and central Asia, where wild cannabis evolved to flower based on age rather than photoperiod. The practical payoff is enormous: an autoflower will move from seedling to harvest in roughly nine to eleven weeks regardless of the light schedule, which lets indoor growers run an 18/6 or 20/4 cycle from start to finish and outdoor growers pull multiple harvests in a single season. Modern autos are nothing like the low-THC ruderalis crosses of the early 2000s — current cultivars rival photoperiod strains for potency and flavor while staying compact, usually finishing between two and four feet tall. Because the clock is fixed, autos punish transplant shock, heavy training, and feeding mistakes more harshly than photoperiod plants, so the standard advice is to germinate directly into the final pot and keep stress to a minimum. They are the right pick for stealth tents, balcony grows, beginners who want a near-foolproof first harvest, and anyone who values a fast turnaround over absolute yield ceiling.
