How to Grow Bruce Banner Fast Version: High-THC Indica
Bruce Banner Fast Version is a seriously potent, 70% indica fast-flowering strain that finishes quickly without giving up any muscle. It pairs a pungent diesel, earthy and sweet flavor with a very high 25-32% THC, and a creative, energetic head over a relaxed indica body, on a high-yielding plant that is ready in just 8-10 weeks of bloom.
This is a faster-finishing take on the legendary Bruce Banner, made by crossing it with a fast-flowering parent. It keeps the robust, resinous character of its namesake, with OG Kush and Strawberry Diesel in its heritage, while shaving weeks off the harvest. The result is a vigorous, 70% indica / 30% sativa hybrid built for impatient growers who still want big, potent buds.

Growing Fast Version Seeds
A Fast Version is not an autoflower. It carries a touch of fast-flowering genetics in its background, but it is still a photoperiod plant, so it flowers on a light change rather than purely on age. You grow it under a long day of around 18 hours through the vegetative stage, then switch to a 12/12 cycle to trigger flowering, just as you would with any photoperiod strain.
What you gain is speed: once you flip, it finishes its bloom quickly, in around 8-10 weeks, which is faster than the original Bruce Banner. Being feminized, every seed grows into a flowering female, so there is no need to sex the plants. Because it finishes so fast, it is a flexible, all-season choice that can fit more than one outdoor run in a warm climate.
Climate and Where to Grow It
Bruce Banner Fast Version does best in a temperate climate with plenty of light and good airflow. As a 70% indica it has a sturdy, bushy structure and stays a manageable 1.4 m, so it fits most tents and plots without a tall room. Its quick finish is a real advantage outdoors in cooler regions, since it beats the worst of the autumn damp.
Indoors, aim for daytime temperatures around 68-80°F (20-27°C) with nights a little cooler, and keep airflow steady over and under the canopy. It prefers lower humidity to protect its dense, resinous, high-THC buds: around 55-60% in veg, nearer 40% in flower, and down to about 30% by harvest, which keeps mould and bud rot away over the fast bloom.
Feeding Schedule (EC Guide)
This is a vigorous, hungry indica that packs on resinous buds fast, so feed it steadily, but still start low and build up as the plant asks for more. Taper right off for the final flush so the diesel-and-sweet flavor comes through clean and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8-1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the resinous buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs a quick 8-10 weeks, faster than a standard photoperiod strain. As a 70% indica it stays short and bushy, filling in dense, chunky, resin-soaked colas. With a very high-THC strain like this, let it finish properly so the trichomes and potency fully develop.
Yields are strong for such a fast plant: around 400-500 g/m² indoors and up to 600 g per plant outdoors, depending on light, pot size and canopy health. Give the heavy colas light support as they fatten, keep the canopy open so light reaches the lower buds, and harvest when most trichomes have turned cloudy for the fullest expression.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry stops the dense, resinous buds staying damp in the middle while the outside dries out, which protects both the diesel aroma and the heavy trichome coat.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the diesel, earthy and sweet notes forward and smooths the smoke, which is exactly what this potent, resinous strain deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Bruce Banner Fast Version is a very resinous, high-trichome plant, so its trim is excellent for making dry sift, bubble hash or rosin. That gives you a bonus run of pungent, high-THC concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Bruce Banner Fast Version has a pungent, moreish profile: a strong diesel punch over an earthy base, with a sweet lift underneath that nods to its Strawberry Diesel heritage. It is a bold, gassy flavor rather than a light or fruity one, and a good cure really rounds out that diesel-and-sweet character in the jar and on the inhale.
Its eight-terpene profile is led by four players. Myrcene anchors the earthy, musky base and the indica body feel, caryophyllene brings the warm, peppery spice behind the diesel punch, terpinolene adds a fresh, fruity-herbal brightness that drives the energetic, creative head, and linalool lays a soft floral sweetness on top. Pinene and humulene round things out with a crisp pine edge and an earthy, hoppy depth.
Effects and Best Use
With its very high 25-32% THC and 70% indica make-up, Bruce Banner Fast Version is a potent, two-sided experience. It is reported as creative, energetic and relaxed: a bright, uplifting cerebral head that sparks ideas and conversation, settling into a heavy, comfortable indica body. This is a strong strain, so a little goes a long way, especially if you have a lower tolerance.
That balance of a lively head and a relaxed body makes it versatile, good for a creative afternoon or a social evening when you still want to feel engaged rather than couch-locked. The combination of serious potency, a fast finish, a big yield and that classic diesel flavor is exactly why Bruce Banner Fast Version is such a popular pick.
Common Problems and Pro Tips
The main thing to respect with this strain is its sheer potency. At 25-32% THC it is one of the stronger options out there, so grow it to finish properly rather than rushing it, and go easy when you try the cured result. The fast bloom is a bonus, not a reason to harvest early, since an early cut trades away a lot of that potency and flavor.
Its dense, chunky indica buds are the other thing to manage. That tight structure can trap moisture, so keep humidity low through flower, run good airflow over and under the canopy, and inspect the fattest colas as harvest nears to stay ahead of mould. A ScrOG net or light low-stress training opens the bushy plant up and lifts the heavy lower buds into the light.
As a pro tip, make the most of its big, fast yield: give it strong light over an even canopy and support the heavy colas as they swell. Keep the feed moderate rather than heavy so you don’t mute the diesel terpenes, run a clean plain-water flush at the end, then follow the trichomes rather than the calendar and cure for three to four weeks for the smoothest, most pungent smoke.
FAQ
How much THC does Bruce Banner Fast Version have?
It is a very high-THC strain, testing at around 25-32%. That puts it among the stronger strains you can grow, so it delivers a powerful, long-lasting effect. If you have a lower tolerance, start with a small amount, because this one hits hard behind its sweet, diesel flavor.
Is Bruce Banner Fast Version an autoflower?
No. Despite the fast-flowering genetics in its background, it is a photoperiod plant, so it flowers on a light change rather than on age. You grow it under long days, then switch to a 12/12 light cycle to start bloom. What it gives you is a faster finish, around 8-10 weeks, not autoflowering behaviour.
Is Bruce Banner Fast Version easy to grow?
Yes, it is beginner-friendly despite its potency. It stays a manageable 1.4 m, finishes fast at 8-10 weeks and yields well, so it is forgiving to grow. The main things to watch are airflow around its dense buds and strong, even light over the canopy to make the most of its big harvest.
What does Bruce Banner Fast Version taste like?
It has a pungent, gassy flavor: a strong diesel punch over an earthy base, with a sweet lift from its Strawberry Diesel heritage. Caryophyllene drives the peppery diesel note and myrcene the earthy depth, while terpinolene adds a fresh, fruity brightness and linalool a soft floral sweetness.
How long does Bruce Banner Fast Version take to flower?
A quick 8-10 weeks once you switch to a 12/12 light cycle, which is faster than the original Bruce Banner. It is a Fast Version, so it blooms on the light change rather than on age but finishes sooner, filling in dense, resinous, high-THC colas over that short flowering window.
How much does Bruce Banner Fast Version yield?
Yields are strong for such a fast plant: around 400-500 g/m² indoors and up to 600 g per plant outdoors. Those numbers depend on light, pot size and canopy health, so give it strong light, an even canopy and support for the heavy colas to get the biggest harvest.
