Bruce Banner

Environment

Prefers a moderately warm environment — broadly in the 70–80°F (21–27°C) range during lights-on, with lights-off temps kept reasonably close to avoid large swings. Relative humidity is best managed on the lower side of the standard flowering range (around 40–50% RH during flower) given how dense its buds tend to become. Good airflow through and under the canopy is important; oscillating fans and adequate exhaust help prevent stagnant pockets. VPD should be monitored and kept in a healthy mid-range — exact targets will vary with your specific environment and grow stage.

Training & canopy

Bruce Banner tends to respond very well to topping and FIM techniques early in veg, helping tame its upward energy and encourage lateral cola development. LST is highly recommended alongside topping to spread branches and even out the canopy. A SCROG net is an excellent fit for this cultivar — its tendency to stretch and push multiple bud sites through a net makes SCROG one of the most efficient methods to maximize your footprint. Leave adequate time in veg to fill the net before flipping, and plan for continued growth after the flip.

Flowering

Expect a pronounced stretch after the flip to 12/12 — Bruce Banner types often push 50–100% height increase in the first two to three weeks of flower, so plan vertical space accordingly or consider flipping earlier than you think necessary. The flowering arc broadly runs around 9–10 weeks, though phenotype variation exists. Early flower weeks are dominated by stretch and pistil development; resin production typically ramps up noticeably in mid-flower (weeks 4–6), with bud swell and trichome maturation filling out the final weeks. Flush timing and harvest reads (trichome colour) should guide the finish — don't rely solely on calendar weeks.

Difficulty

Vigorous growth and significant stretch demand active canopy management and feeding attention — not ideal for first-time growers.
