Bruce Banner 3 Fast Cannabis Seeds
Bruce Banner 3 Fast is a feminised photoperiod cannabis seed from Original Sensible Seeds that delivers monstrous yields in a fraction of the usual flowering time. Built from Strawberry Diesel, Black Domina, and Colorado Ghost OG, this 65% indica / 35% sativa hybrid pushes out up to 800g/m² indoors after just 20–55 days of flowering. That speed-to-harvest ratio is genuinely unusual for a plant that can stretch to 300cm tall.
Pack Size
This listing comes in a pack of 3 feminised seeds. Every seed is photoperiod — you control the flip to flower by switching your light cycle to 12/12. No autoflower genetics here, so you decide when she's ready.

Growing a plant that can hit 300cm? You'll want proper training tools. A SCROG net keeps the canopy flat and even, maximising light penetration across those fat colas. Pair with fabric pots for better root aeration — Bruce Banner 3 Fast responds well to a healthy root zone given how aggressively she produces.
Bruce Banner 3 Fast Genetics and Lineage
The original Bruce Banner #3 phenotype descends from OG Kush and Strawberry Diesel — a sativa-leaning combination famous for sky-high THC and enormous plants. Original Sensible Seeds kept the Strawberry Diesel parent but swapped OG Kush for two new cultivars: Black Domina and Colorado Ghost OG. That single change shifted the genetic balance from sativa-dominant to 65% indica, brought the flowering time down dramatically, and altered the terpene profile.
Black Domina is a four-way indica cross (Northern Lights, Ortega, Hash Plant, Afghani SA) known for dense bud structure and fast finishing. Colorado Ghost OG brings OG Kush lineage back into the mix but through a specific phenotype selected for resin production and vigour. The Strawberry Diesel parent contributes peppery, citrusy, and floral terpenes — you'll notice those on the nose, especially during the last two weeks of flower when the trichome coverage gets properly frosty.
Worth noting: according to research published in PLOS ONE, the common "indica vs sativa" labels don't always reflect actual genetic or chemical differences between strains (Schwabe & McGlaughlin, 2021). The 65/35 split is the breeder's classification based on parentage and observed growth patterns, not a guarantee of specific effects. What you can count on is the structural behaviour: shorter internodal spacing than the original #3, thicker stems, and denser flowers.
Growing Bruce Banner 3 Fast Seeds
This is where Bruce Banner 3 Fast really earns its name. A flowering window of 20–55 days is exceptionally quick. Most photoperiod strains sit in the 56–70 day range, so you're potentially shaving weeks off your cycle. That said, the 20-day figure is the absolute minimum — expect most phenotypes to land closer to the 45–55 day mark for fully mature buds with proper trichome development.
Indoor growers can expect up to 800g/m², which is a serious haul. Outdoor plants, given enough root space and sunlight, can push to 1000g per plant. Plants can reach 300cm if left unchecked, so unless you've got a warehouse ceiling, you'll want to manage height.
- Germinate using the paper towel method or directly in a starter plug. Bruce Banner 3 Fast seeds are feminised, so every seed should produce a female plant — no need to sex them later.
- Veg for 3–5 weeks depending on your space. She grows vigorously, so if your tent is 180cm or shorter, consider topping early to encourage lateral branching.
- Apply SOG (Sea of Green) or SCROG (Screen of Green) techniques to control height and maximise canopy coverage. SCROG works particularly well here — weave branches through the net during late veg and early flower.
- Flip to 12/12 when the canopy fills roughly 70% of your net. She'll stretch during the first two weeks of flower, filling the remaining gaps.
- Monitor trichome development from day 40 onwards. Clear trichomes mean she's not ready. Milky white with 10–20% amber is the sweet spot for most growers.
- Get your trimming crew sorted before harvest. At 800g/m², you're looking at a genuinely long trim session. Wet trimming is faster; dry trimming preserves more terpenes. Your call.
Why Bruce Banner 3 Fast Seeds Stand Out
We've seen plenty of "fast" versions of popular strains come through, and honestly, some of them sacrifice too much for speed. The buds come out airy, the terpene profile thins out, or the yield drops to compensate. Bruce Banner 3 Fast doesn't seem to have that problem. Original Sensible Seeds managed to keep the yield figures genuinely impressive — 800g/m² indoors is in the top tier for any photoperiod strain, fast or otherwise.
The THC range of 20–29% puts this firmly in the heavy-hitter category. According to research on high-THC cannabis products, concentrations at the upper end of this range can produce adverse effects including anxiety and paranoia in some users (Carberry et al., 2021). That's not a reason to avoid growing it — it's a reason to respect what you're cultivating and advise anyone sampling the harvest to start small.
The honest limitation? That 300cm height. If you're growing in a standard 200cm tent, you need to train this plant aggressively or she'll outgrow your space before you even flip to flower. Compared to something like Original Sensible Seeds' own auto-flowering varieties, Bruce Banner 3 Fast demands more hands-on management. But the payoff — in weight, potency, and speed — is hard to argue with.
Bruce Banner 3 Fast Flavour and Aroma
The Strawberry Diesel parentage drives the terpene profile here. Expect peppery, citrusy, and floral notes — a combination that's more complex than the typical "diesel and skunk" you get from a lot of OG-derived strains. The Black Domina influence adds a darker, earthier undertone that becomes more noticeable after a proper cure. Give the dried buds at least two weeks in jars, burping daily, and the flavour layers open up considerably.
The "Fast" breeding process altered the flavour compared to the original Bruce Banner #3. The original leans more heavily on the OG Kush side — gassy, piney, with a sharp lemon bite. This version is softer on the nose, more rounded. If you've grown the original and loved that fuel-forward profile, be aware that Bruce Banner 3 Fast is a different animal. Still excellent, but different. Think of it as a cousin rather than a clone.
Trichome coverage on the colas is dense. We're talking about buds that look like they've been rolled in sugar — which makes sense given the THC ceiling of 29%. Those trichomes are where the terpenes live, so handle the buds gently during harvest and trimming to preserve as much of that resinous coating as possible.
Bruce Banner 3 Fast vs the Original Bruce Banner #3
| Feature | Bruce Banner 3 Fast | Original Bruce Banner #3 |
|---|---|---|
| Breeder | Original Sensible Seeds | Dark Horse Genetics |
| Genetics | Strawberry Diesel x Black Domina x Colorado Ghost OG | Strawberry Diesel x OG Kush |
| Indica/Sativa | 65% Indica / 35% Sativa | 40% Indica / 60% Sativa |
| Flowering Time | 20–55 days | 56–65 days (typical) |
| Indoor Yield | Up to 800g/m² | Up to 600–700g/m² (typical) |
| THC | 20–29% | 25–29% |
| Dominant Flavour | Peppery, citrusy, floral, earthy | Diesel, pine, sharp lemon |
| Plant Structure | Indica-dominant: denser, shorter internodes | Sativa-dominant: taller, stretchier |
The Fast version trades the sativa-dominant structure and flavour profile for speed, yield, and a more manageable plant shape. If you're after the classic Bruce Banner #3 experience — long-limbed sativa growth and that gassy OG bite — this isn't quite it. But if you want a faster turnaround with heavier harvests and don't mind the indica lean, Bruce Banner 3 Fast is the stronger practical choice for most indoor setups.
Frequently Asked Questions
How long does Bruce Banner 3 Fast take to flower?
The breeder lists 20–55 days of flowering. Realistically, most phenotypes finish closer to 45–55 days. Check trichomes with a jeweller's loupe from day 40 onwards — milky with some amber is the harvest window.
How much THC does Bruce Banner 3 Fast produce?
THC ranges from 20% to 29% depending on phenotype, growing conditions, and cure quality. The upper end of that range puts it among the strongest strains available. According to research, high-THC products can cause anxiety and paranoia in sensitive individuals (Carberry et al., 2021).
Is Bruce Banner 3 Fast suitable for beginners?
The seeds are feminised, which removes the need to identify and remove males — that's one less thing to worry about. The main challenge is height management. If you can handle basic training techniques like topping and SCROG, you'll be fine. If this is your very first grow, something shorter and more forgiving might be easier to start with.
Can I grow Bruce Banner 3 Fast outdoors?
Yes, and outdoor plants can yield up to 1000g per plant. She can reach 300cm in height, so she'll need space. The fast flowering time means she'll finish earlier in the season than many photoperiod strains, which is an advantage in northern European climates where autumn rains can cause bud rot.
What does Bruce Banner 3 Fast smell and taste like?
Peppery, citrusy, and floral from the Strawberry Diesel parent, with darker earthy notes from Black Domina. It's softer and more rounded than the original Bruce Banner #3, which leans harder into diesel and pine. A two-week cure in jars brings out the full terpene complexity.
What training techniques work best for Bruce Banner 3 Fast?
SCROG is the top pick — it controls the 300cm height potential while maximising light exposure across the canopy. SOG also works well if you're running multiple plants in a smaller space. Top early in veg to encourage bushier lateral growth.
How does Bruce Banner 3 Fast compare to autoflowering Bruce Banner seeds?
Autoflowering versions flower on their own schedule regardless of light cycle, typically finishing in 70–80 days from seed. Bruce Banner 3 Fast is photoperiod — you control when flowering starts. The trade-off is more control and higher yields (800g/m² vs typical auto yields of 400–500g/m²), but a longer total cycle if you include veg time.
