Gorilla Glue Auto vs Bruce Banner Auto
Everything you need to know before buying seeds — THC, yield, difficulty, effects, and the best places to buy in 2026.
Quick Comparison
Gorilla Glue Auto Overview
Fast Buds' Gorilla Glue Auto brings the legendary GG4 experience to the autoflower world without compromise. Testing up to 29% THC, this auto version preserves the extreme resin production and heavy-hitting effects that made the original famous. The plants stay compact but produce dense, sticky buds coated in the same glue-like trichomes that named the original strain. For growers, GG Auto is one of the best high-potency autoflowers available — manageable size, fast cycle, and the same sticky, pungent buds that extraction artists love.
🌱 Growing Tips
Plant directly in final container (3–5 gallon). Support branches from day 45 onward as buds get heavy and sticky. LST during weeks 2–3 significantly increases yields. Moderate feeding — start at 50% strength. Carbon filtration is essential for the diesel aroma. Harvest when trichomes are mostly cloudy with 10–20% amber.
Bruce Banner Auto Overview
Fast Buds' Bruce Banner Auto captures the Hulk-like potency of the original in an autoflowering format that's ready in just 70–77 days. This is one of the highest-yielding autoflowers on the market, with plants that grow larger than most autos while maintaining the 25–29% THC levels that made Bruce Banner legendary. The berry-diesel flavor profile is preserved beautifully, and the effects follow the same pattern as the photoperiod version — an immediate cerebral rush followed by progressive full-body relaxation.
🌱 Growing Tips
BB Auto grows larger than most autos — use 5 gallon containers and give it space. LST is highly recommended to manage height and increase bud sites. This strain is a heavy feeder for an auto — can handle full-strength nutrients by mid-flower. Support branches during late flower. The 70–77 day cycle is slightly longer than GG Auto but the extra yield makes it worthwhile.
Head-to-Head Comparison
Fast Buds' two most potent autoflowers, battling for the crown. Both push the limits of what autoflowers can achieve on potency, but they're built for different purposes. Gorilla Glue Auto is the compact resin machine — shorter plants, faster cycle (63–70 days), and the extreme stickiness that makes it perfect for extract production. Bruce Banner Auto is the yield king — larger plants, higher per-square-meter yields, and a more complex high that starts cerebral before settling physical. The extra 7–10 days of grow time for Bruce Banner pays dividends in extra bud weight. For growers running perpetual harvests in tight spaces, GG Auto's compact size and faster turnaround make it more efficient. For growers maximizing single harvests, BB Auto's superior yields are hard to argue with. Both produce genuine top-shelf flower that rivals photoperiod quality.
