The specs in one line: 20-25% THC, <1% CBD, 8-10 weeks flowering, 400-500g/m2 reported. Best indoor or outdoor. moderate grow.

Smell-first, this one announces itself early in flower — sharp citrus rind layered over a fuel note that hangs in the tent long after harvest. Black Hulk from Blimburn is a feminized sativa that tests consistently in the 20–25% THC range, with indoor runs returning 400–500 g/m² after an 8–10 week flower period. The stretch is real: growers working low-ceiling spaces should top early or switch to LST before she gets ahead of you. Difficulty sits at moderate, meaning you'll want at least one successful grow under your belt — she rewards growers who dial in VPD and don't skip the late-veg training.

For Canadian outdoor growers, the 8–10 week finish is workable in most southern provinces if you're starting seeds indoors in April, but she'll need a sheltered spot once temperatures drop toward 10°C at night. Best suited to intermediate growers with climate control or a long, warm finishing window.

This sativa-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Black Hulk delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Black Hulk

Black Hulk is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Black Hulk features a fruity, citrus, diesel, earthy terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Black Hulk 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.
