Description
Born from the cross of GMO Auto and Mythic OG, Atlas Seed's GMO OG Auto carries the unmistakable genetic weight of two deeply respected indica lines. Expect the savory, diesel-forward aromatics that GMO is known for, rounded out by the earthy, resinous character of Mythic OG. Effects lean firmly into the indica side, delivering a heavy, grounding experience suited to evening cultivation and quiet appreciation. At 25 percent THC and above, this one commands respect.
As a feminised autoflower, GMO OG Auto moves from seed to harvest in 10 to 12 weeks regardless of light cycle, making it a strong candidate for year-round indoor runs or fast seasonal outdoor crops where a long grow window is not available. Every seed in the pack is feminised, so cultivators can plan their space without accounting for males. The indica-dominant structure typically means compact, branch-heavy plants that manage well in tents and smaller rooms. For growers who want legitimate top-shelf potency from an autoflowering line, Atlas Seed has built a reliable path to it here.

about this product
GMO OG Auto brings Atlas Seed's fuel-laced, 25%-plus potency to an autoflowering format, ready for beginners who refuse to compromise on strength or yield.
Atlas Seed built this one with beginners in mind, rating it as an easy grow that doesn't demand specialist knowledge or complex light schedules. As an autoflower, it moves from seed to harvest in 10 to 12 weeks on its own internal clock, so there's no need to manage photoperiod changes. It's one of the more forgiving ways to grow a genuinely heavy-hitting indica.
GMO OG Auto sits in the high-yield bracket, capable of producing 450 to 750 grams per plant outdoors and 450 to 600 grams per square metre indoors. For an autoflowering variety, those numbers are genuinely impressive and reflect the quality of the GMO and Mythic OG genetics behind it. Getting there consistently comes down to good nutrition and adequate light intensity rather than any advanced technique.
The aroma is bold and unmistakable — a sharp, fuel-forward diesel character inherited from the GMO side, layered over earthy, skunky depth from the Mythic OG lineage. Gassy and pungent are the words most growers reach for, so odour management indoors is worth factoring into your setup. The flavour carries those same chem and earthy notes through to the finish.
The effects lean firmly indica — expect a heavy, couch-locking body sensation that moves toward sleepiness as it develops. With THC consistently above 25 percent, the onset is substantial and not particularly suited to daytime activities. This is an evening strain built for unwinding, and it rewards those who approach it with a little patience and respect for its potency.
