Spec sheet first — strain: indica, seed type: feminized, THC: 17-22%, yield band: medium, environment: indoor or outdoor.

Seed Supreme lists this at $29.87 — the upper end of the comparison range (up to $25.98). Pack options: 3-seed at $29.87, 5-seed at $44.55, plus larger sizes.

Smell-first: crack a cured bud of Black Demon OG and you get a wall of damp earth and fresh pine resin — nothing subtle about it. This feminized indica runs 8–10 weeks to flower and pulls 400–550 g/m² under decent light, which puts it firmly in the productive-but-not-fussy category. THC tests between 17–22%, so the potency is real without being a novelty act. Rated moderate in difficulty, it handles both indoor and outdoor environments without demanding expert-level dialing.

The growth structure is compact and dense, typical of a heavy indica, meaning you'll want to stay on top of canopy airflow to avoid moisture buildup late in flower. Expect thick, resinous buds that carry that pine-and-earth profile straight through the dry and cure. A solid pick for growers who want reliable feminized seeds, a predictable flowering window, and a classic sedating indica effect without chasing a trendy flavor profile.

THC Level & Potency

Black Demon OG Cannabis delivers THC levels of 17-22%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing Black Demon OG Cannabis

Black Demon OG Cannabis 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 400-550 g/m². Plants typically reach 80-150 cm 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 40-50% 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 Demon OG Cannabis features a earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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 Demon OG Cannabis 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.
