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 actually backs the potency with a high worth having and a grow that does not punish you. This review is about where it came from, the cut we have chosen to stock and why, what to expect from it, and how the three versions we sell differ.
Where Bruce Banner Came From
Bruce Banner is a cross of OG Kush and Strawberry Diesel, and the detail that matters is which cuts. The OG Kush side was the Ghost cut, one of the most revered OG selections of its era, and the Strawberry Diesel was Reservoir Seeds’ version, itself a cross of Strawberry Cough and Sour Diesel. So underneath that famous name sits Ghost OG on one side and a Strawberry Cough and Sour Diesel grandparent line on the other. That is a serious stack of West Coast genetics, and it explains a lot about how the strain behaves.
It was released by Delta 9 in Denver around 2009 as their house strain, and the demand was something else at the time, long lines and pre-order waitlists from people trying to get hold of it. Dark Horse Genetics is also central to the origin story, and there is the usual scene argument over exactly who did what, but the genetics and the reputation are not in dispute. What came out the other side was a benchmark that newer high-THC hybrids still get measured against.
The Cut We Stock: Bruce Banner #5
Here is the part worth knowing before you buy, because it is where most write-ups get lazy. The original Bruce Banner threw five phenotypes. Numbers 2 and 4 fell away, which left three: #1, #3 and #5. The one that made the name was #3, the most OG Kush-leaning cut and the potency king. That is the cut crowned High Times’ Strongest Strain on Earth in 2014 at a 28.3% reading, the highest figure recorded at a High Times Cannabis Cup at the time, and it is the one almost every seed simply labelled Bruce Banner descends from.
We have gone a different way. The cut we stock is the #5, and that is a deliberate choice, not an accident of supply. #5 leans to the Strawberry Diesel side of the family, and growers who have run both will quietly tell you it is the bigger yielder and often the sweeter, more flavoursome smoke, giving up only a little on the raw THC number while still sitting firmly in high-THC territory. It is the connoisseur’s pick of the Bruce Banner cuts, the one people who have actually grown the strain tend to reach for, and it is the one you get from us.
The High
The effect is what kept Bruce Banner relevant after the novelty of the THC number wore off. It comes on fast and cerebral, a clear, euphoric, creative lift with real energy to it, the sort of head high you can actually do something with rather than one that pins you down. The Strawberry Diesel side drives that. Then the OG Kush half rolls in underneath as a warm body relaxation that rounds the whole thing off instead of flattening it.
That balance is the strain’s real trick. At a sensible amount it stays functional and bright, more of a daytime high than an evening one. Push the dose and the strength is genuinely there, so it is not a strain to be casual with if your tolerance is not up to it. Go easy until you know how it sits with you.
What to Expect
A sativa-dominant hybrid around 60/40, the Strawberry Diesel-leaning #5 cut. Firmly high-THC, a touch sweeter and a heavier yielder than the record-setting #3. A fast, clear, creative head rush with real energy, settling into a warm body relaxation that rounds it off rather than knocking you flat. Functional and daytime-capable at a sensible amount, and seriously strong if you push it.
Flavour and Terpenes
Bruce Banner smells like its parents argued and both won. The dominant note is diesel and fuel, straight off the OG Kush and that Sour Diesel grandparent, the kind of pungent gas that fills a room the moment you open the jar. Under it sits the Strawberry Diesel side, a sweet berry note with a thread of citrus, and an earthy, faintly herbal back end that some phenos push toward sage and mint. Caryophyllene, myrcene and limonene lead the terpene profile, with a touch of humulene. On the inhale it reads berry and gas, on the exhale it turns sweeter and more citrus, and the #5 we stock pushes that Strawberry Diesel berry sweetness a little further forward than the gassier #3. It is loud, and that loudness is part of why people remember it.
Growing Bruce Banner
The OG Kush in the lineage gives Bruce Banner a bushy, branchy structure, which makes it a natural fit for a SCROG net or a sea of green, and the open frame helps airflow through what becomes a very dense, resinous canopy. Photoperiods flower in around 9 to 10 weeks, the buds finish heavy and frosty, and a cold snap late in flower will often pull dark magenta and purple tones into the leaf. That heavy resin is also why it has always been a favourite for hash and rosin.
One thing I want to flag, because it trips people up. Growers see OG Kush in the lineage and feed it cautiously, expecting the nutrient sensitivity that OG-dominant strains are known for. Bruce Banner does not behave that way, and the #5 makes the point even more sharply, because it leans to the robust Strawberry Diesel side. The Strawberry Diesel genetics add real toughness, and in practice it carries a higher feed than its OG parentage suggests, sitting comfortably around 1.7 to 1.8 EC through mid-flower with a dialled-in root zone. Underfeed it and you leave yield on the table. The one genuine watch-out is humidity through late flower, because those dense colas can hold moisture and invite rot, so keep the air moving. For the full feeding schedule, indoor and outdoor yields and the Australian harvest timing, the product page carries the detail.
Who It Suits
Bruce Banner suits growers chasing proven high-THC genetics that still grow with some forgiveness, smokers who want a strong but functional, daytime-leaning high rather than a pure knockout, and anyone pressing their own hash or rosin off that heavy resin. It is not the place to start if you are new to potent flower, and it is not the one if you want something gentle.
The Three Versions We Stock
Bruce Banner comes in three forms here. The photoperiod feminised version is the one to grow for the biggest yields and full control over size, since you decide when to flip and how long to veg. The fast version keeps the photoperiod character but finishes roughly two weeks sooner, which earns its place in a shorter or less reliable season. The autoflower flowers on age rather than light, running smaller and finishing the whole cycle in about 10 to 12 weeks, the pick when you want speed and simplicity. All three are feminised. If the photoperiod-versus-auto choice is new to you, our guide to the difference between autoflower and feminised seeds lays it out.

Not sure a high-THC hybrid is right for you?
Answer six quick questions and we’ll match you to three strains based on your setup, experience and the effect you’re after.
Bruce Banner is one of the few strains that genuinely lived up to its own hype, and the #5 is the smart way to grow it. The short version is below.
Key Takeaways
Serious West Coast pedigree. Bruce Banner is Ghost OG Kush crossed with Reservoir’s Strawberry Diesel, released by Delta 9 in Denver around 2009 and still a benchmark for high-THC hybrids.
We stock the #5. #3 is the famous, record-setting cut, but the one we have chosen is the #5, the Strawberry Diesel-leaning pick that yields harder and often tastes sweeter while staying firmly high-THC.
Strong but functional. A roughly 60/40 sativa hybrid, firmly high-THC, fast and creative up front, warm and relaxing underneath, daytime-capable at a sensible dose.
Takes more feed than you would think. The Strawberry Diesel side makes it robust, so it carries higher EC than its OG parentage suggests. Watch late-flower humidity on the dense buds.
Three versions. Available as photoperiod, fast version and autoflower seeds, all feminised.
Frequently Asked Questions
Is Bruce Banner indica or sativa?
It is a sativa-dominant hybrid, leaning roughly 60% sativa to 40% indica. The high reflects that, opening with a fast, energising, creative lift before the OG Kush side settles in as a warm body relaxation.
How strong is the Bruce Banner strain?
Very strong. The Bruce Banner line tests in the mid-to-high twenties for THC, and the #3 phenotype was recorded at 28.3% when High Times named it the Strongest Strain on Earth in 2014. The cut we stock is the #5, which gives up a little of that raw potency in exchange for yield and flavour but still sits firmly in high-THC territory, well clear of an average strain at 15 to 20%. It is not the place to start if you are new to potent flower.
Who bred Bruce Banner?
It is credited to Delta 9, who released it as their house strain in Denver around 2009, with Dark Horse Genetics also central to the origin story. The cross is the Ghost cut of OG Kush with Reservoir Seeds’ Strawberry Diesel, which is itself Strawberry Cough crossed with Sour Diesel.
What is the difference between Bruce Banner #3 and #5?
They are two phenotypes of the same cross. #3 leans to the OG Kush side and is the famous, most potent cut, the one that won the titles. #5 leans to the Strawberry Diesel side, tends to yield more and can taste sweeter, giving up a little raw THC in exchange while staying firmly high-THC. Out in the wider market most Bruce Banner is the #3, but the cut we stock is the #5, which a lot of seasoned growers actually prefer.
What does Bruce Banner taste like?
Diesel and fuel lead, from the OG Kush and Sour Diesel side, over a sweet berry and citrus note from the Strawberry Diesel parent and an earthy, faintly herbal back end. Caryophyllene, myrcene and limonene drive the profile. It reads berry and gas on the inhale and turns sweeter on the exhale.
How long does Bruce Banner take to flower?
Photoperiods flower in around 9 to 10 weeks. The fast version finishes roughly two weeks sooner, and the autoflower completes its whole cycle in about 10 to 12 weeks from germination.
Is Bruce Banner hard to grow?
Not for a strain this strong. It has a bushy, branchy structure that suits a SCROG or sea of green, and it is more robust than its OG Kush parentage suggests, carrying a higher feed thanks to the Strawberry Diesel side. The main watch-out is humidity around the dense buds in late flower. The strength is in the smoke, not the difficulty of the grow.
What versions of Bruce Banner can I get in Australia?
Three. The photoperiod feminised version for full control and the biggest yields, the fast version for a shorter finish, and the autoflower for speed and simplicity. All three are feminised.
