GMO Auto: old-school funk in autoflower form
A departure from Fast Buds’ usual sweet, fruity profiles, GMO Auto goes for flavour with character. The bank crossed a Californian GMO cut with its Chemdog Auto to keep GMO’s original profile in a stable autoflower. It’s a feminized F4, 80% indica and 20% sativa, with up to 28% THC.
A medium-sized, well-branched plant
GMO Auto forms medium-sized, well-branched plants (XL size) of 80–120 cm. Indoors it yields 450–600 g/m², and outdoors 50–200 g per plant. Fast Buds highlights its suitability for extraction. The bank gives a harvest time of 10–11 weeks, slightly longer than other autos.
Aroma, flavour and effect
An old-school funk profile: earthy, garlicky, herbal and spicy, with diesel notes inherited from Chemdog. It won’t suit every palate, but it’s exactly what growers tired of candy profiles are looking for.
At 80% indica and up to 28% THC, GMO Auto delivers a mainly body-focused, relaxing and long-lasting effect. The feeling growers report most is relaxation, followed by good mood, some sleepiness and the munchies. An evening strain for experienced consumers.
Why choose GMO Auto?
- The original profile of the Californian GMO cut, now as an autoflower.
- A funky garlic, earth and diesel aroma, unlike the usual sweet autos.
- Up to 600 g/m² indoors and great for extraction.
- 80% indica: medium-sized, well-branched plants.

Growing tips
Like all autoflowers, GMO Auto switches to flowering on its own, with no change in light schedule. Sow it straight into its final pot to avoid transplant stress, give it 18–20 hours of light indoors and start feeding at gentle doses. For week-by-week doses, see our Grotek feed chart for autoflowers.
