About Black Demon

Black Demon combines reliable indica-dominant structure with heavy resin production and a dark, fruity flavour. It performs well indoors under controlled conditions and gives consistent yields when growers manage humidity and airflow.

Grow Difficulty:

Growing Black Demon requires moderate skill and careful feed schedules to avoid nutrient burn. Variable British weather means indoor climate control or protective housing is advisable to reduce mould risk.

Flowering Time:

Flowering indoors generally completes in eight to ten weeks. Outdoors in York the crop usually finishes by late September in a good season.

Yield:

Yields are medium to high when plants receive consistent light and nutrients. Under strong LED setups and good maintenance you can expect 400–550 g per square metre indoors.

Height:

Plants maintain a medium, bushy structure that responds well to topping and low-stress training. The manageable height makes them suitable for modest indoor spaces.

Environment:

Indoors in York Black Demon thrives under LED canopies with stable temperature and humidity control. Outdoors in York it prefers a sheltered, sunny spot and vigilant mould prevention in autumn.

Climate:

Growing Black Demon in York requires attention to damp and late-season rain because of variable British weather. Use a greenhouse, polytunnel or indoor LED setup to control humidity and avoid mould.
