GMO Auto by Fast Buds

For years Fast Buds leaned towards sweet Sherbet profiles. GMO Auto is their deliberate turn in the opposite direction: they started with a GMO clone brought in from California and crossed it with their Chemdog Auto to preserve the original terpene identity in autoflowering format. The bank also presents it as champion of the Autoflower World Cup 2026.

A terpene profile that is not for everyone

There is no fruit here. The profile is garlic, onion and earthy mushroom over a diesel base, with that savoury note that makes GMO recognisable from the first whiff. It is a variety that divides opinion, and the bank itself makes no bones about it.

It is worth understanding one detail before buying: the bud comes out slightly more open than in other lines of the catalogue. It is not a density fault, it is a breeding decision to avoid sacrificing terpene quality. If you are interested in this profile, the catalogue also features it in the Garlic Sherb by Grand Cru Genetics.

Cultivation: patience in exchange for terpenes

It is one of the bank's slowest autos, with 10-11 weeks of cycle versus the usual 8 or 9 in their catalogue. Anyone looking for quick turnaround has other options among the Autoflowering Seeds; anyone coming for the terpenes will find that the extra time is part of the deal.

The plant stays at 80–120 cm, with solid branching and short internodes, an XL shape easy to manage in a tent. Production ranges from 450 to 600 g/m² indoors and 50 to 200 g per plant outdoors, with an 80% indica dominance that shows in the compact structure and the effect.

An auto designed for washing

Fast Buds rates it as a great washer: resin-rich flower with very pronounced terpenes, which is exactly what someone extracting is after. For hash-making, the load of trichomes and aromatic intensity matters more than tight bud structure, so that slightly more open structure stops being a drawback.

In effect, the bank's community describes it above all as relaxing, with a touch of euphoria at the beginning and sleepiness as it progresses. The rest of the auto catalogue is under Fast Buds.
