Bruce Banner is the strain that taught a lot of growers what genuinely high THC feels like, and the name is the whole joke. Mild-mannered on the surface, an absolute monster underneath.
I have run plenty of high-THC genetics outdoors over the years, and Bruce Banner is one people always ask me about. It earned that reputation honestly. For a stretch it was the strongest thing anyone could lay hands on, and unlike a lot of strains that chase a number and forget everything else, it backs the potency with a high worth having and a grow that does not punish you.
Bruce Banner is a sativa-leaning hybrid bred from OG Kush and Strawberry Diesel. It comes on fast and cerebral before settling into warm physical relaxation. The version we stock is Bruce Banner #5, the closely held, Strawberry Diesel-leaning phenotype rather than the more common, record-setting #3. This review covers where the strain came from, what #5 changes, what the effects and flavour are like, and how the photoperiod, fast and autoflower versions differ.
Bruce Banner Genetics and Origin
Bruce Banner was bred in Colorado by Jason Holck of Dark Horse Genetics, using an OG Kush mother and a Strawberry Diesel male. The parentage explains the whole strain: OG Kush supplies the deep fuel, resin and physical weight, while Strawberry Diesel brings the sweeter fruit, energy and stretch.
The line was among the original genetics offered through Holck’s Delta 9 Alternative Medicine dispensary in Denver. Several phenotypes emerged from the original project, but #3 and #5 became the names that lasted. Bruce Banner #3, the more OG-dominant selection, tested at 28.35% THC at the 2013 Denver High Times Cannabis Cup. At that point it was the highest THC result recorded at a High Times Cup, and the result turned Bruce Banner from a Colorado favourite into an international benchmark for potency.
Why We Stock Bruce Banner #5
Most Bruce Banner write-ups stop at #3. That is understandable: #3 is the famous phenotype, the record holder and the version most seed-bank lines reference. But it is not the only serious expression of the original cross.
We stock Bruce Banner #5. Dark Horse describes #5 as the more closely held Strawberry phenotype of the line: only a few percentage points behind its #3 sister in potency, but marked by an unmistakable sour-strawberry character. It leans further toward the Strawberry Diesel side, which brings the berry sweetness forward and gives the plant a brighter, more energetic personality.
That is why #5 earns its place in our catalogue. It retains the resin, strength and OG depth that made Bruce Banner famous, but gives more room to the strawberry-diesel flavour and productive sativa side of the family. It is not a generic Bruce Banner sold under the famous name. It is a deliberate phenotype choice.
Jason’s Verdict
Bruce Banner earned its reputation through more than a THC result. The real trick is how usable the high can remain at a sensible amount: fast, clear and creative up front, with enough OG Kush underneath to round it out. The #5 is the version I would choose because the sweeter Strawberry Diesel character comes through without giving away the strength that made the line famous.
Bruce Banner Effects: What Is the High Like?
The effect comes on quickly. The opening is cerebral, euphoric and energising, with a creative lift that feels more useful than foggy. That is the Strawberry Diesel side speaking. It can suit daytime or social use at a measured amount because the head stays relatively clear even while the potency is obvious.
The OG Kush influence arrives underneath rather than taking over immediately. Physical tension eases and the experience becomes warmer and more settled, but it does not automatically flatten the energetic opening. That movement from a bright head rush into balanced body relaxation is what separates Bruce Banner from strains that offer a large THC figure and little else.
It is still a genuinely strong strain. Increase the amount and the functional edge can disappear quickly, so it is not a casual starting point for someone unfamiliar with high-THC flower.
Bruce Banner Flavour and Terpene Profile
Bruce Banner smells like its parents argued and both won. Diesel and fuel lead, drawn from the OG Kush and Sour Diesel side of the family. Beneath that sits sweet strawberry and berry, a line of citrus, and an earthy, faintly herbal finish. Caryophyllene, myrcene and limonene commonly lead the terpene profile, with some expressions also showing humulene.
The #5 we stock pushes the Strawberry Diesel character further forward than the gassier #3. Expect berry and fuel on the inhale, followed by a sweeter citrus-diesel finish. It is a loud profile, but it has more shape than simple raw gas.
Growing Bruce Banner in Australia
Bruce Banner develops a branchy frame that responds well to canopy management, while the photoperiod version generally flowers in around 9 to 10 weeks. Finished flowers can become dense and heavily resinous, and cooler late-flower conditions may bring darker magenta and purple tones into the leaf. The resin production also explains the line’s longstanding popularity for hash and rosin.
The main Australian consideration is late-flower humidity. Those dense flowers need consistent airflow in coastal and subtropical conditions, including northern NSW and Queensland. The standard photoperiod gives the most control over size and the largest yield ceiling. Where the outdoor season is shorter or less reliable, Fast Bruce Banner offers the same basic photoperiod control with a meaningfully earlier finish.
The #5 is more robust than its OG-heavy reputation might suggest and should not be starved simply because OG Kush appears in the lineage. In a dialled-in root zone it can carry a solid feed through mid-flower, but plant response should determine the final EC rather than any fixed number. Keep the canopy open, watch moisture around the flowers and avoid pushing nitrogen late.
Who Bruce Banner Suits
Bruce Banner suits people seeking proven high-THC genetics with a more energetic, functional opening than a heavy indica. It also suits growers who value resin, yield potential and a distinctive berry-diesel profile. The grow itself is manageable, but the potency is not especially beginner-friendly. Anyone wanting something gentle or deeply sedating from the outset should look elsewhere.
Standard vs Fast vs Auto Bruce Banner
We stock three feminised versions of Bruce Banner. The right choice depends less on which one is “best” and more on whether you value maximum control, an earlier photoperiod finish or a fixed autoflower timeline.
| Version | Type | Timeline | Best for | Choose it when |
|---|---|---|---|---|
| Bruce Banner Feminised | Photoperiod | About 9–10 weeks flowering, plus veg | Maximum control and yield potential | You can manage the light cycle and want full control over plant size |
| Fast Bruce Banner | Fast photoperiod | Roughly two weeks faster than standard | Earlier outdoor finish without giving up veg control | Your season is shorter or late-season weather is unreliable |
| Auto Bruce Banner | Autoflower | Approximately 10–11 weeks from seed | Speed, compact size and no light flip | You want a fixed lifecycle or several smaller runs |

Frequently Asked Questions
Is Bruce Banner indica or sativa?
Bruce Banner is a sativa-dominant hybrid, generally described as approximately 60% sativa and 40% indica. Its effects reflect that balance: an energising, cerebral opening followed by warmer OG Kush body relaxation.
What are the Bruce Banner strain’s genetics?
Bruce Banner was bred by Jason Holck of Dark Horse Genetics from an OG Kush mother and a Strawberry Diesel male. Strawberry Diesel itself carries Strawberry Cough and Sour Diesel heritage, which helps explain Bruce Banner’s mix of sweet fruit, fuel and energetic effects.
How strong is the Bruce Banner strain?
Bruce Banner is firmly high-THC. The famous #3 phenotype tested at 28.35% THC at the 2013 Denver High Times Cannabis Cup, which was the highest result recorded at a High Times Cup at the time. Potency varies with phenotype and growing conditions, and the #5 we stock is described by Dark Horse as only a few percentage points behind #3.
What is the difference between Bruce Banner #3 and #5?
They are two selected phenotypes from the original OG Kush × Strawberry Diesel project. #3 leans more heavily toward OG Kush and became famous for its 28.35% THC result. #5 is the more closely held, Strawberry Diesel-leaning phenotype, known for a sweeter sour-strawberry character and a brighter sativa expression while remaining highly potent. Sacred Seeds stocks #5.
What are Bruce Banner’s effects?
Bruce Banner usually begins with a fast cerebral lift: euphoric, creative and energising. As the experience develops, the OG Kush side adds body relaxation without immediately erasing the brighter opening. At higher amounts, its potency becomes much less functional.
What does Bruce Banner taste like?
Diesel and fuel lead over sweet strawberry, berry and citrus, followed by an earthy OG finish. The #5 phenotype brings more of the Strawberry Diesel sweetness forward than the more OG-dominant #3.
How long does Bruce Banner take to flower?
The standard photoperiod version generally flowers in approximately 9 to 10 weeks. Fast Bruce Banner finishes roughly two weeks sooner, while Auto Bruce Banner completes its full lifecycle in approximately 10 to 11 weeks from seed.
Is Bruce Banner difficult to grow?
It is manageable for a high-potency hybrid. The plant develops a branchy structure that suits canopy management and the #5 has a robust Strawberry Diesel influence. The main watch-outs are late-flower humidity around dense flowers, adequate airflow and avoiding excessive nitrogen late in the cycle.
Which Bruce Banner version should I choose?
Choose the standard photoperiod for maximum control over veg time, plant size and yield potential. Choose the fast version for an earlier photoperiod finish, especially where late-season weather is a risk. Choose the autoflower when a fixed lifecycle, smaller footprint and no change to the light schedule matter most.
