Bruce Banner Auto takes one of the most talked-about West Coast heavyweights and squeezes it into a fast, day-neutral package. Sweet Seeds lists this seventh-generation autoflower at 18–25% THC, and the breeder notes that some plants push past that ceiling, all on a plant that goes from seed to harvest in about 9 weeks.
The draw is a loud, layered nose that drifts between tropical fruit, flowers and Diesel fuel, wrapped around an upbeat, long-lasting high. Plants top out at 50–110 cm (20–43 in), which keeps them easy to handle in a small tent or on a balcony.
Indoors, Sweet Seeds lists 400–500 g/m² (1.31–1.64 oz/ft²), while outdoor plants return 50–150 g (1.8–5.3 oz) per plant. That is serious output for a plant that never needs a change in light schedule.
Lineage: A Colorado Legend With Autoflowering Speed
The original Bruce Banner was bred in Colorado and built a reputation as one of the strongest American strains of its era. Sweet Seeds took an elite clone of that photoperiod plant and crossed it with a selected line of its own Gorilla Girl XL Auto (SWS82), a tall, productive autoflower from the breeder’s XL range.
Seven generations of autoflowering work later, the hybrid carries variety code SWS91 and a genetic split of 58.7% Sativa, 41.1% Indica and only 0.2% Ruderalis. That sliver of Ruderalis supplies the automatic flowering trigger while bud quality and potency stay firmly in modern-hybrid territory.
Aroma, Flavor and Effect
Open a jar and sweetness lands first, quickly followed by ripe tropical fruit and a bouquet of floral notes. Underneath, a sharp Diesel streak and damp earth give the profile real backbone, so it never tips over into pure candy.
On the palate the fruit stays up front while fuel and soil linger on the exhale. Think of slicing a mango in a garage where a truck has just been refueled: juicy, sweet and unmistakably gassy at the same time.
Sweet Seeds describes the effect as happy, stimulating and creative. Expect a bright, euphoric lift that gets ideas flowing and conversation moving, with enough staying power for a long creative session or an afternoon with friends.
Growing Bruce Banner Auto Indoors and Outdoors
Because it flowers on its own, Bruce Banner Auto needs no switch to 12/12. Run it under 18/6 or 20/4 from the first day to the last, and plan on roughly 9 weeks from germination to harvest. Sow straight into the final container, around 11–19 liters (3–5 gallons), to avoid transplant setbacks.
Indoors, gentle LST during the first three to four weeks opens the Sativa-leaning frame into an even canopy and helps fill the space toward 400–500 g/m² (1.31–1.64 oz/ft²). Keep feeding light early, raise it through bloom, and run a carbon filter, because the Diesel-fruit aroma travels.
Outdoors, plant after the last frost in a warm, sunny spot. The short cycle allows a spring run and a second summer run in many American climates, and vigorous plants in rich soil deliver 50–150 g (1.8–5.3 oz) per plant while staying at a discreet 50–110 cm (20–43 in).
