Bruce Banner Feminized — The Heavy-Hitter You've Been Waiting For

Quick answer: Bruce Banner Feminized (OG Kush x Strawberry Diesel) is a photoperiod feminized sativa-dominant hybrid testing 24-30% THC, flowering 9 to 10 weeks from the 12/12 switch with indoor yields up to 500g/m2.

Key takeaways

• OG Kush x Strawberry Diesel — photoperiod feminized, sativa-dominant at roughly 60% sativa / 40% indica.
• THC runs high across independent and seed bank sources alike: commonly cited in the 24-28% range, with select phenotypes and seed bank listings reaching 29-32%.
• Flowering takes 9 to 10 weeks from the 12/12 switch — on the longer side for a sativa-leaning hybrid, largely due to a pronounced stretch phase.
• Indoor yields run up to roughly 500g/m2 with strong feeding; outdoor plants can produce 300-650g per plant in a warm, sunny climate, but Canadian outdoor growers should budget for a demanding finish (see growing section below).
• A sharp diesel-and-earth opening from the OG Kush side gives way to a sweet strawberry finish from Strawberry Diesel — myrcene-led terpene profile with caryophyllene and limonene support.

Bruce Banner carries one of the more documented competition records in the seed bank world: bred in 2008 by Dark Horse Genetics in Los Angeles, the #3 phenotype went on to win the Denver US Cannabis Cup and was recorded as one of the most potent strains tested in High Times Cannabis Cup history at the time. That record is part of why THC numbers for this strain get quoted so high — but as with most Cannabis Cup strains, what you'll actually grow depends heavily on phenotype and conditions, not just the headline number from one competition cut.

What is Bruce Banner Feminized's genetic background?

Bruce Banner Feminized is a cross of OG Kush and Strawberry Diesel, originally bred from Reservoir Seeds' Strawberry Diesel and a Ghost OG-derived cut of OG Kush. The original breeding program produced five numbered phenotypes; #2 and #4 were dropped, while #1, #3, and #5 were kept for their potency. Phenotype #3 — compact, fast-finishing, and indica-leaning relative to its siblings — became the benchmark cut that most seed banks reference today, while #1 and #2-style phenotypes run taller with a slower finish and a stronger sativa lean, based on grower-documented phenotype descriptions from the breeder's original selections.

The result is a sativa-dominant hybrid — roughly 60% sativa to 40% indica — that inherits OG Kush's resin production and fuel-forward aroma alongside Strawberry Diesel's energetic, uplifting character. This isn't the same lineage as an autoflowering "Bruce Banner Auto" you may see listed elsewhere in the seed trade, which typically adds ruderalis genetics for automatic flowering; this feminized version is full photoperiod, with no autoflowering trait and full control over veg time before you flip to 12/12.

A note on the numbers: THC figures for Bruce Banner vary meaningfully across sources — some seed banks cite 25-32%, others land closer to 24-28% — largely because different breeders' cuts, and even different phenotypes from the same cut, test differently. We're presenting the range you'll actually see across sources here rather than picking the single highest number.

What does Bruce Banner Feminized smell and taste like?

The terpene profile is led by myrcene, with caryophyllene and limonene contributing meaningfully behind it — a combination that produces an earthy, musky base with a peppery edge from the caryophyllene and a citrus brightness from the limonene. See our cannabis terpenes guide for how each of these compounds shapes aroma and effect. On the palate, expect the classic Bruce Banner signature: a sharp, fuel-forward diesel opening (straight from the OG Kush side) that mellows into a sweet, fruity strawberry note on the exhale (courtesy of Strawberry Diesel).

The visual signature leans toward dense, resin-frosted colas with a real trichome load — consistent with a strain bred specifically for potency. Effects come on fast and cerebral: an early rush of euphoric, energizing effect typical of sativa-dominant hybrids, mellowing into a more relaxed body feel as the high develops. Given the potency, this is a strain worth approaching cautiously if you have a lower tolerance — and given the resin load, it's also a strong candidate for making your own extracts once you've got trim to work with.

How difficult is Bruce Banner Feminized to grow?

Moderate to demanding — this is a strain better suited to a grower with at least one full photoperiod cycle under their belt than a complete beginner. Bruce Banner stretches aggressively during the first few weeks of flower, meaning a plant that looks compact at the 12/12 switch can double or more in height before settling — budget vertical space accordingly, especially in an indoor tent.

The plant also feeds heavily. Expect to run a fuller nutrient schedule than you would for a more modest indica-leaning strain, and watch for nutrient deficiencies showing up faster than expected during the stretch and into mid-flower. See our cannabis pH guide if you're troubleshooting nutrient uptake issues — pH swings are a common hidden cause of deficiency symptoms that look like a feeding problem but aren't.

Outdoors, Bruce Banner prefers a warm, sunny, low-humidity climate closer to Mediterranean or Californian conditions — a real consideration for Canadian growers. It can still finish outdoors in regions with a sufficiently long, warm season (parts of southern Ontario and BC's interior), but growers in cooler, wetter regions should watch humidity closely in late flower given the strain's dense bud structure. See our outdoor cannabis growing calendar for province-specific timing.

What are the best growing tips for Bruce Banner Feminized?

• Plan for serious vertical stretch. Bruce Banner can more than double in height in the first 2-3 weeks of flower. If you're growing in a tent, flip to 12/12 earlier than you would with a more compact strain, or top and train during veg to manage final height.

• Feed on the heavier side, and watch your pH. This strain's resin and yield potential come with a genuinely heavier appetite. Keep a close eye on pH through veg and flower — nutrient lockout shows up faster on a heavy feeder than on a lighter-feeding strain.

• Support the branches before they need it. Dense, resin-heavy colas on a tall sativa-leaning structure are a recipe for snapped branches late in flower. Stake or trellis proactively rather than reacting once buds have already filled out.

• Track terpene development, not just trichome color, when planning harvest. Given the strain's aromatic complexity — diesel up front, strawberry on the back end — pulling slightly earlier or later can shift which note dominates. See our guide to when and how to harvest cannabis for a trichome-based timing approach.

• Give the cure real time. A slow, patient cure lets the myrcene-caryophyllene-limonene profile settle into the diesel-to-strawberry signature this strain is known for, rather than a flatter, one-note smoke.

How long does Bruce Banner Feminized take to flower, and what yield can you expect?

Flowering runs 9 to 10 weeks from the 12/12 switch — on the longer end for a sativa-dominant hybrid, driven largely by the extended stretch phase before buds fully develop. As with any photoperiod strain, this covers flowering only; total time to harvest also depends on how long you choose to veg.

Indoor yields commonly reach up to around 500g/m2 with strong feeding and training, though realistic first-run numbers often land lower while you dial in this strain's heavier nutrient needs. Outdoors, yields show a wide spread depending on climate and season length: commonly cited in the 300-400g-per-plant range in temperate conditions, with up to 650g per plant reported in ideal, sunny, full-season climates.
