Bruce Banner Auto brings one of the hardest-hitting American sativa classics into a fast, fuss-free autoflower. Seedstockers built it from an OG Kush x Strawberry Diesel base crossed with Sour Diesel Auto, keeping the loud diesel-and-berry terpenes, massive resin-loaded colas and energetic daytime lift that made the original so famous.
There is no light switch to worry about. Set the timer to 18/6 or 20/4, leave it alone and the plant finishes in about 12 weeks from seed, a little longer than the average auto but well worth the extra days.
Yields are serious: 550–650 g/m² (1.80–2.13 oz/ft²) indoors under LED and 150–250 g/plant (5.3–8.8 oz/plant) outdoors. Plants are vigorous and branchy, stretch well into early flower and finish with long, frosted central colas.
With THC in the 20–26% range and a rating for intermediate growers, it is a strain for people who want maximum flavor and production and are ready to give the plant a bit of attention.
Lineage: OG Kush, Strawberry Diesel and Sour Diesel
The photoperiod Bruce Banner line comes from crossing OG Kush with Strawberry Diesel, a pairing known for sky-high potency, fuel-soaked terpenes and a sweet berry undertone. It quickly became a West Coast favorite thanks to its strength and bag appeal.
Seedstockers added Sour Diesel Auto to bring in automatic flowering and reinforce the diesel side of the profile. The outcome is a sativa-dominant autoflower with stable performance, predictable timing and premium terpene expression.
Aroma, Flavor and Effect
Nothing about this plant is discreet. The aroma is a loud diesel-fuel funk with a sweet strawberry undertone, strong enough that a good carbon filter is a must in late flower.
The flavor follows suit: pungent diesel up front, sweet fruity berries across the mid-palate and a sharp, almost peppery kick on the exhale. Picture a basket of ripe strawberries left on the hood of a running pickup truck.
The effect is a heavy-hitting sativa rush that lights up the mind, sparks creativity and delivers a clean lift in energy. The body stays loose while the head stays sharp, making Bruce Banner Auto a true daytime powerhouse.
Given the potency, it rewards a measured approach, especially for anyone new to strong sativas.
Growing Bruce Banner Auto Indoors and Outdoors
Indoors, run 18/6 or 20/4, with 20/4 under LED being the breeder’s reference setup for 550–650 g/m² (1.80–2.13 oz/ft²). This strain likes a slightly higher feed than most autos in late flower: increase potassium during bloom and watch the buds fatten up. Give it extra space and good airflow, since it is vigorous and branchy.
The breeder’s top tip is to add a small support stake by week 8. The central colas get heavy enough to snap thinner branches if they are not braced, and they usually need light support by week 9.
Outdoors, plant in 15–20 L (4–5.3 gal) containers for 150–250 g/plant (5.3–8.8 oz/plant). Sunny climates suit it most, but even in cooler regions it still finishes reliably within its 12-week window. Start the seed in its final container to keep growth moving from day one.
