Quick read: 21-26% THC, 80-150 cm mature height, 70 days bloom. Genetics: Bruce Banner #3 Auto (Herbies Seeds genetics). Difficulty: easy.

The lab panel on this one tends to stop people mid-scroll: 21–26% THC from an autoflowering plant that finishes in around 70 days and still manages 550–650 g/m² indoors. Bruce Banner #3 Auto pulls those numbers without asking much in return — difficulty is rated easy, it runs well indoors or out, and the profile stays grounded rather than showy: earthy base, a thread of sweetness, nothing that overpowers the room.

For Canadian growers working a short outdoor window — think BC interior, southern Ontario, or anywhere frost shows up before September is done — a 70-day flower cycle from an auto means you can time a late-spring start and pull a harvest before the weather turns. The genetics come from Herbies Seeds' own Bruce Banner #3 Auto line, so consistency run-to-run is solid. Best suited to newer growers who want genuinely high-potency results without managing photoperiod timing or a complicated feed schedule.

Genetics & Lineage

Bruce Banner #3 Auto traces its genetics to Bruce Banner #3 Auto (Herbies Seeds genetics). This hybrid-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Herbies Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Bruce Banner #3 Auto delivers THC levels of 21-26%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Bruce Banner #3 Auto

Bruce Banner #3 Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 70 days with yields of 550-650 g/m². Plants typically reach 80-150 cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Bruce Banner #3 Auto features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Bruce Banner #3 Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
