Autoflower Cannabis Seeds

Autoflower Cannabis Seeds

Autoflower cannabis seeds deliver fast, light-independent harvests—no 12/12 switch required. Bred with ruderalis genetics, they move from seedling to bloom on their own, typically finishing in 8–11 weeks. That makes them ideal for first-time growers, short seasons, and anyone who wants reliable, repeatable results without babysitting the light schedule. Compact by nature, modern autos still push impressive yields with dense, resinous buds and terpene-rich profiles.

For best results: run 18–20 hours of light from start to finish, use 3–5 gal (11–19 L) pots, keep early growth stress-free, and favor gentle training (LST) over topping after week three. Feed moderately, avoid heavy transplants, and aim for steady temps and airflow to support fast metabolism. Outdoor growers can stack multiple runs per season; indoor growers love the calendar certainty.

Explore our Autoflower seeds below—curated for vigor, flavor, and consistency—so you can plan your grow by weeks, not months.

Classic Calm in Auto Form

19 August 2025

Mazar Auto grew short, sturdy, and super frosty. The buds smelled earthy and spicy with that old-school hash aroma. The smoke is smooth, heavy, and relaxing—perfect for sleep or unwinding after work. Easy grow, reliable results, no stress.

Gelato Auto grew dense, frosty buds with a crazy dessert-like smell—sweet cream, citrus, and a little earthy funk. The smoke is smooth and flavorful, and the high is happy and relaxing without being too heavy. Great for afternoons or winding down after work.

Big, Loud, and Knockout Strong

31 July 2025

Fat Bastard Auto is an absolute beast—short and chunky, with huge resin-packed buds that smell like skunky citrus mixed with sweet earth. One joint and I was done—full-body melt, couch-lock, the whole package. If you want a heavy-hitting auto, this one’s it. Big yield, big flavor, big chill.

Tommy

Loud, Fruity, and Straight-Up Wild

21 July 2025

Monkey Dick Auto from Lighthouse Genetics was a straight banger. Grew short and bushy but packed on fat, sticky buds that smelled like tropical fruit punch with a little skunk on the back end. The high smacked me goofy—happy, giggly, and then fully couch-blasted. Easily one of the loudest strains I’ve run. Total vibe.

Old-School Chill in Auto Form

21 July 2025

Mazar Auto brought that classic Afghan calm, but in a quick and tidy grow. Stayed low, super frosty, and smelled like earth, spice, and warm hash. The high is mellow, grounding, and peaceful—great for pain, sleep, or just tuning out the noise. Zero anxiety. Just pure comfort.

Big Yields, Bigger Couch Lock

21 July 2025

Devil XXL Auto came in hot—grew tall, fast, and thick with chunky red-haired buds that reeked of spice and diesel. Smoked a blunt and didn’t move for two hours. Heavy, heady, and straight-up demonic in the best way. Not for lightweights. Great for after-hours zoning.
