Bruce Banner Strain Review: THC, Effects, Flowering Time & Yield

Bruce Banner is one of the strongest strains we sell: an Original OG Kush × Strawberry Diesel hybrid that tests at 25 to 32% THC, flowers in 63 to 70 days and gives 550 to 700 g/m² indoors — a sweet, fruity-diesel flavour on top of a heavy, two-stage high. This Bruce Banner strain review covers its genetics, THC, effects, flowering time and yield, plus what growers from Toronto to the Maritimes wrote about it in the reviews on our product page.

Bruce Banner at a glance

What is Bruce Banner?

Bruce Banner takes its name from the Hulk’s alter ego, and the joke is on purpose: it looks calm and green, then it hits hard. The strain was bred in Colorado in the early 2010s by crossing Original OG Kush with Strawberry Diesel. The third phenotype, “Bruce Banner #3”, became famous in 2014 when a lab test came back at just under 29% THC, at the time the highest ever recorded at a cannabis competition. Our feminized Bruce Banner is grown from that same OG Kush × Strawberry Diesel lineage and selected for the same traits: big, dense, frosted flowers and a THC range of 25 to 32%.

Searching for the Bruce Banner strain on Leafly, AllBud or a dispensary menu? You will find Bruce Banner #1, #3 and #5 listed as separate cuts. Strain names are not protected, so what you grow depends on the seed bank. Everything on this page describes the Bruce Banner feminized seeds sold by Quebec Cannabis Seeds.

Is Bruce Banner indica or sativa?

Bruce Banner is a balanced hybrid that leans slightly sativa in how it grows: it stretches a lot, builds long branches and takes well to topping. The high follows the same pattern — the Strawberry Diesel side arrives first as a bright, happy rush, and the OG Kush side settles in afterwards as deep physical relaxation. If you want a strain that is purely sedating, look at an indica like Granddaddy Purple; if you want something that stays energetic, a sativa like Sour Diesel is a closer fit.

Smell and flavour: sweet strawberry over diesel fuel

The aroma is the first thing people notice. Strawberry Diesel brings a sweet, ripe strawberry note with a sharp diesel edge, and OG Kush adds the earthy, piney, slightly floral base that OG fans know. In the jar it reads as fruit and fuel; on the exhale it is sweeter, with a lingering herbal finish. One Ontario customer summed it up as a “smooth, nice smoke with a slow rising punch” — the flavour is friendlier than the potency suggests.

Appearance: big, hard buds under a layer of frost

Bruce Banner grows large, chunky colas that stay dense right through the plant. The flowers are bright lime green with orange pistils, and by week seven they are covered in trichomes — several growers on our product page describe them as “covered with frost” and “much bigger and thicker than any other strains growing under the same conditions”. Expect a tall plant: outdoors in Canada it regularly reaches two metres or more.

Bruce Banner effects

The effect is a fast, euphoric, creative lift followed by a heavy, calming body high. The first twenty minutes are talkative and upbeat; after that the OG Kush side takes over and most people want to sit down. At 25 to 32% THC it is not a beginner’s smoke, and a small amount goes a long way. Customers describe it as “potent buds”, “very powerful” and “a slow rising punch”. One reviewer grew it well but simply did not enjoy the end product, which is a fair reminder that very strong strains are not for everyone.

How strong is Bruce Banner? THC content

Bruce Banner delivers 25 to 32% THC and under 1% CBD, depending on the growing conditions, the phenotype and the harvest window. That puts it at the very top of our catalogue alongside strains like Runtz. If you are new to high-THC cannabis, start with a single small dose and wait.

Growing Bruce Banner: flowering time and yield

Bruce Banner is rated moderate, but most of the difficulty is managing its size, not keeping it alive. Indoors it flowers in 63 to 70 days and yields 550 to 700 g/m² with good light and a proper feeding schedule. It stretches hard in the first two weeks of flower, so top it in veg, use a trellis or ScrOG net, and leave headroom. Outdoors it is typically ready in October, with up to 800 g per plant in a sunny spot and good soil. It handles Canada’s shorter, cooler season well: the dense buds tolerate a little rain, and growers in Ontario and Quebec report it as hardy and mould tolerant. Those figures are ranges, not promises. Keep airflow around the thick colas in a wet September, and watch trichomes rather than the calendar.

Indoor is measured per m², outdoor per plant — the two figures aren’t directly comparable. Real grower results vary widely.

What growers report

We would rather give you the whole picture, so here is what customers wrote on the Bruce Banner product page (21 reviews, rated 4.5 out of 5 at the time of writing).

• Size and structure: a grower who started a single seed got “a 7-foot monster” after topping twice, almost spherical at 6.5 feet across. Another calls it a “nice stretcher” that produces “nice big hard buds covered with frost”. Plan your space accordingly.
• Outdoor yields in Canada: a first-time grower in north Toronto, coached by the reviewer, pulled about 14 ounces (roughly 400 g) from one plant in a sunny spot. Another reviewer averaged about 400 g per plant from four plants, and a Quebec grower reported 450 g per plant outdoors.
• Timing: an indoor grower harvested at 9 weeks and 5 days of flowering — right inside our 63 to 70 day range. One outdoor grower saw flowering start in mid-July, earlier than the rest of his garden.
• Hardiness: “very easy to grow, hardy and mold resistant”, “big buds and a good yield whether it’s grown in full sun or partial shade”. Several growers note that it clones easily and takes LST and topping without complaint.
• Germination: most reviewers report 100%, including seeds that were a year old. Two reviewers had poor luck with a pack, and one notes seed husks that needed removing and some odd first leaves — so it is not a strain we would recommend for a very first grow, even though the plant itself is forgiving once established.

The takeaway: give Bruce Banner room, top it early, and it rewards you with some of the biggest, frostiest buds in a Canadian garden.

Is Bruce Banner right for you?

If you want a very high-THC hybrid with a sweet strawberry-diesel flavour, heavy yields and a plant that shrugs off a cool Canadian fall, Bruce Banner is a strong choice — as long as you have the vertical space. It is one of our best-selling feminized strains and a regular in our featured strains. If you want the same genetics on an autoflower timeline, see Auto Bruce Banner.
