Our take

Frostbanger Auto brings together GG4, Bruce Banner, and Sour Diesel genetics in a single feminized autoflower that tops out at 31% THC and finishes in just nine weeks — no light-schedule changes needed. The aroma runs fresh and spicy with a sweet edge. It suits growers who have a crop or two under their belt and want serious potency without a long wait.

Completes seed-to-harvest in 9 weeks indoors or out, with no light-schedule adjustment required
Indoor yields reach up to 2.2 oz/ft² and outdoor plants can produce up to 7.5 oz per plant
XL plant reaching 28–47 inches — substantial canopy for an autoflower, with room to train early

Growing notes

Frostbanger Auto fits indoor tents, outdoor beds, greenhouses, and mixed-light setups equally well. Expect plants to stretch to 28–47 inches, so allow vertical space or apply low-stress training in the first few weeks. The 9-week total cycle makes scheduling straightforward. Intermediate growers will get the most from it; beginners can manage with attentive watering and feeding.
