GMO Auto: Fast Buds Brings a California Legend Into the Auto World
GMO Auto comes from a cross between the GMO Cut, a California clone known for its raw, savoury character, and Chemdog Auto, which carries ruderalis genetics through Fast Buds' own Auto 1 lineage (itself rooted in Lowryder 1 x Fast Bud Auto). The result is an 80% indica / 20% sativa autoflower that keeps the funky, garlic-onion-mushroom identity of the original clone intact, delivered in a compact, light-schedule-free package. At 28% THC, this is firmly in seasoned-user territory. Fast Buds entered it in the Autoflower World Cup 2026, where it took the top spot, though that claim comes from the brand's own page rather than an independent body. The F4 designation reflects multiple generations of stabilisation, giving growers consistent phenotype expression across a pack of seeds.
Compact Frame, Serious Resin, No Light Schedule Required
Indoors, GMO Auto reaches 80-120 cm, compact enough to fit most tents without any canopy management, though LST will help fill the space and push yields toward the upper end of the 450-600 g/m² range. Outdoors, the plant stays within the same 80-120 cm height range, with yields running 50-200 g/plant depending on conditions. Seed to harvest takes 10-11 weeks with no light cycle to manage. The flowers are slightly more open in structure than denser indica lines, a trait the brand attributes to terpene preservation rather than a production compromise, and one that makes GMO Auto a standout choice for hash-making and solventless extraction. The resin load is heavy, and the wash performance reflects it.
Earthy, Herbal, Spicy, Then the Floor Drops Out
The aroma hits first: deep, earthy, herbal, with a spicy edge that leans peppery and savoury rather than anything sweet or fruity. It is a deliberately niche profile, and the reason growers who are tired of candy-forward autos seek this strain out specifically. The effects follow the indica-dominant genetics closely, relaxing and body-heavy, building steadily into something long-lasting that suits evening use. There is a secondary uplifting and creative note early on, but the dominant arc is sedating, with sleepiness and a strong appetite response as the session progresses. This is not a strain for the middle of the afternoon.
