Bruce Banner
Also known as: Banner, OG Banner, Bruce, BB#3
Breeder: Dark Horse Genetics (Jason Holck)
Bred in 2008 by Jason Holck in Denver, Colorado, Bruce Banner is a sativa-leaning hybrid that earned its name from a joke on Holck's surname ('Holck' → 'Hulk') after a fan at a String Cheese Incident concert dubbed him 'Bruce Banner.' The #3 phenotype tested at 28.35% THC at the 2013 Denver Cannabis Cup, earning 'Most Potent Strain' and setting the highest THC ever recorded at a High Times Cup at the time. It was one of the original 12 strains offered at Holck's now-defunct Delta 9 Alternative Medicine dispensary. High Times ranked it #9 on their '25 Greatest Strains of All Time' list in 2014. The strain is renowned for extreme resin production, heavy trichome coverage, and a loud diesel-strawberry nose. Bruce Banner was bred in 2008 by Jason Holck of Dark Horse Genetics as a Colorado-based breeding project crossing OG Kush with Strawberry Diesel. The name was a play on Holck's own last name — 'The Incredible Hulk' / Holck — not an attempt to appeal to children, though the strain was briefly placed on Oregon's list of banned strain names in 2016 for that perceived association. Five phenotypes were originally selected, with #3 becoming the breakout star due to its record-setting THC levels. By 2016, Bruce Banner #3 had been named to High Times' list of the 25 Greatest Strains of All Time, cementing its place in cannabis history. THC levels consistently range from 25-30%, with the terpene profile featuring caryophyllene, myrcene, and limonene. The effects deliver an immediate cerebral rush of euphoria and creative energy before settling into a relaxing body high.
Lineage & Genetics
Cross: OG Kush x Strawberry Diesel
OG Kush (mother): The specific cut is believed to be Ghost's OG — a legendary Los Angeles phenotype known for dense structure, fuel-forward terpenes, and high potency. Strawberry Diesel (father): A Reservoir Seeds hybrid of Strawberry Cough x Sour Diesel. Holck won the seeds in an auction. It contributes the sweet strawberry-berry aromatics and sativa-leaning growth vigor to the cross.
Lineage Dispute
The specific OG Kush cut is debated. Dark Horse Genetics' own catalog lists simply 'OG Kush.' GentlemanToker and multiple community sources identify it as Ghost's cut of OG Kush. SeedFinder.eu catalogues it as 'OG Kush [original OG 2004].' Original Sensible Seeds' version references 'Colorado Ghost OG.' The Strawberry Diesel parent (Strawberry Cough x Sour Diesel) was sourced from Reservoir Seeds via auction. Five phenotypes were selected (#1–#5); #3 (OG-dominant) became the standard, #5 (Strawberry-dominant) is the other surviving cut.
Terpene Profile
Caryophyllene — Spicy, peppery warmth
Myrcene — Earthy, herbal, musky foundation
Limonene — Bright citrus, lemon zest
Humulene — Woody, hoppy, earthy
Alpha-Pinene — Fresh pine, forest-like brightness
Linalool — Floral, lavender sweetness
Aroma: Room-filling diesel and sour fuel on the break, layered with sweet wild strawberry and berry jam. Underlying earthy-kushy funk with citrus peel and a spicy pepper bite from the caryophyllene. The nose is notoriously loud — multiple sources warn it can overwhelm a grow room or make transport conspicuous. High Times described the #3 as having a 'nose-crackling, rocket-fuel aroma.'
Flavor: Inhale leads with sweet strawberry and berry, transitioning mid-palate to a diesel-fuel and earthy OG backbone. Exhale carries spicy, peppery notes with a lemon-citrus finish. Less sweet than the aroma suggests — the diesel and kush funk dominate the actual smoke. Concentrates tend to amplify the diesel component via hydrocarbon extraction or boost the berry sweetness via solventless rosin.
Effects & Experience
Onset: Fast and hard-hitting. The cerebral rush arrives within minutes — a surge of euphoria and energy that users consistently describe as immediate and intense. The 'Hulk smash' reputation is earned at the onset.
Opens with a powerful euphoric head high that promotes creativity, focus, and social energy. As the high develops, the OG Kush indica side emerges with full-body relaxation that complements the mental stimulation without replacing it. At moderate doses, the balance is uplifting and functional. At higher doses, the OG lineage takes over and can shift into heavy sedation and couch-lock — described by budtenders as 'starts like a coffee kick, ends like a nightcap whiskey.'
Duration: 3–4+ hours. The cerebral phase dominates the first 1–2 hours, with the body relaxation building steadily and extending the tail end.
Commonly Reported Uses
Grower's Notes
Bruce Banner by Dark Horse Genetics is a sativa-leaning hybrid (approximately 60% sativa / 40% indica) that earned legendary status for its extraordinary THC production — the #3 phenotype tested at 28.35% THC at the 2013 Denver Cannabis Cup, making it the most potent strain ever measured at a High Times competition at that time. Created by Jason Holck (aka OG Ironlung) in 2008 by crossing an OG Kush mother with a Strawberry Diesel male, Bruce Banner produces five distinct phenotypes, with #3 and #5 being the most commercially available. The #3 is the award-winning OG-dominant cut known for extreme potency; the #5 leans more into the OG Kush side with a slightly more relaxed effect profile.
Growth Structure and Training
Cultivation is rated moderately difficult, with stretch management being the single most important planning consideration for indoor growers. The Strawberry Diesel sativa genetics drive significant vertical growth — expect a 50-80% height increase from the start of the 12/12 flip through approximately week three of flower. A plant at 60 cm at flip will reach 90-110 cm before stopping. This makes early training essential: top at the 3rd-5th node, implement LST to spread the canopy horizontally, and strongly consider a SCROG setup to maintain a flat, even canopy. Without intervention, indoor plants can easily exceed tent height limits.
Flowering Time and Harvest
Flowering runs 8 to 10 weeks, with most growers harvesting at 9-10 weeks for optimal resin development. Indoor yields are impressive at 500-600 g/m2 under optimized conditions, and outdoor plants can return 600-900+ g per plant given full sun and adequate growing season. The strain is a heavy feeder — provide more nitrogen and CalMag than you would for typical hybrids during vegetation, and transition to phosphorus-heavy bloom fertilizers once flowering initiates. Monitor for tip burn and adjust accordingly.
Environment and Climate
Environmental targets should hold temperatures at 65-80°F (optimal range 70-80°F during the day), with the caveat that Bruce Banner can tolerate cooler temperatures better than many strains — the OG Kush genetics contribute genuine cold resilience. Humidity control becomes critical in late flower: the dense, resin-heavy buds are susceptible to mold, so maintain 40-45% RH from mid-flower onward. Strong canopy airflow is essential — position oscillating fans to keep air moving through the dense flower sites.
Environment and Climate
Bruce Banner thrives in warm, dry climates when grown outdoors. Harvest timing outdoors is early October. The plants develop vibrant green buds coated in a thick layer of frosty trichomes, reflecting the high cannabinoid content. The terpene profile combines the diesel-fuel punch of Strawberry Diesel with earthy, sweet berry notes and OG Kush's characteristic pine undertones. Caryophyllene, myrcene, and limonene dominate, with limonene contributing the bright, nose-crackling citrus lift that earned the #3 phenotype its \"rocket fuel aroma\" reputation. A thorough 3-4 week cure is recommended to mellow the diesel edge and fully develop the sweet fruit undertones that make Bruce Banner's flavor profile so distinctive.
History & Origin
In the mid-2000s, Jason Holck was a college student and novice grower in Colorado who won Strawberry Diesel seeds (Strawberry Cough x Sour Diesel) from a Reservoir Seeds auction. He crossed Strawberry Diesel pollen onto an OG Kush mother (believed to be Ghost's cut) and selected five phenotypes. A fellow enthusiast at a String Cheese Incident concert nicknamed Holck 'Bruce Banner' (The Incredible Hulk — 'Holck' → 'Hulk'), and the name stuck to his signature strain. In 2008, Holck opened Delta 9 Alternative Medicine in Denver — one of Colorado's first 20 dispensaries — where Bruce Banner was one of 12 debut strains. Drop days drew lines around the block with customers camping out Thursday night for Friday releases. By 2013, Bruce Banner #3 tested at 28.35% THC at the Denver Cannabis Cup, earning 'Most Potent Strain' — the highest THC ever recorded in High Times Cup history at that time. In 2014, High Times ranked it #9 on their '25 Greatest Strains of All Time.' In 2016, Oregon's OLCC banned the name for allegedly appealing to children. Holck later founded Dark Horse Genetics to continue breeding with the Banner line.
