GMO Auto by Barneys Farm – 24% THC Indica-Dominant Autoflower with Garlic & Diesel Aroma

GMO Auto by Barneys Farm is a high-powered, indica-dominant autoflowering strain packing 24% THC, delivering a fast-growing, big-yielding experience with a bold garlic-diesel punch that stands out in any grow space.

Are you tired of weak, flavorless autoflowers that barely get you high?

Most autoflowers sacrifice potency and taste for speed. You end up with wispy buds, low resin, and a forgettable buzz that doesn’t match the hype.

What happens when you keep settling for average genetics?

You waste time, space, and money on plants that underperform. You miss out on that full-body relaxation, the rich terpene kick, and the dense, trichome-covered colas that make growing worth it. Worse, poor genetics can lead to weak seedlings, mold issues, or inconsistent results.

The solution? A no-compromise autoflower bred from elite GMO stock

GMO Auto by Barneys Farm combines the legendary potency and aroma of GMO with robust autoflowering genetics, giving you a fast, reliable grow with top-shelf results. No light cycle changes, no guesswork—just plant, feed, and harvest heavy, fragrant buds in under 11 weeks.

What this strain delivers in just 70–75 days

You get a compact powerhouse that grows up to 1.10 m (3.61 ft) indoors, producing up to 600 g/m² (2.12 oz/ft²) of frosty, aromatic bud. Outdoors, expect 230–300 g (8.11–10.58 oz) per plant, with strong resistance to mold and pests thanks to its indica structure and dense canopy.

Personal Experience of Pevgrow’s CEO (Alan)

I grew GMO Auto in my 60x60 cm tent under a 300W LED, and damn—this thing packed a punch. From day one, it showed vigor, with thick stems and dark green leaves. I used light LST to open up the canopy, but didn’t top it—no need with this auto. By week 6, the smell was insane: garlic bomb with a diesel backdraft. I flushed with Canna Flush for 7 days, harvested at day 74, and ended up with just over 580 g/m² of rock-hard, trichome-glazed buds. The high is heavy but not couch-locking—perfect after work. If you want a fast, flavorful, high-THC auto that actually delivers, this is it. I’ve tried dozens, and GMO Auto stands in the top 5 for consistency and power.
