About Black Patronus

Black Patronus is an indica-dominant hybrid valued for dense, dark buds and a heavy, relaxing effect. Selected for resinous trichomes and rich berry-spice flavour, it performs best under attentive humidity control and protection from late-season damp, making it a strong candidate for growers in Northumberland who use polytunnels or greenhouses to extend the short outdoor growing season.

Grow Difficulty:

Growing Black Patronus is intermediate and benefits from steady attention to ventilation and mould prevention. Under a short outdoor growing season you should plan to use protection such as polytunnels to ensure full maturation.

Flowering Time:

Indoor flowering completes in roughly 8–10 weeks under a standard 12/12 cycle. Outdoors it will require similar timing and may need shelter to finish reliably.

Yield:

Yields are medium to high when humidity and nutrient schedules are well managed. Expect respectable outdoor results in Northumberland if buds are protected from autumn damp.

Height:

Plants maintain a medium stature with sturdy main colas. They respond well to topping and low-stress training.

Environment:

Indoors, Black Patronus does well under controlled humidity and moderate light, producing compact, resinous flowers. Outdoors in Northumberland it benefits from greenhouse cover or polytunnels to manage wet conditions and extend ripening time.

Climate:

Growing Black Patronus in Northumberland requires planning for the short outdoor growing season and likely sheltering in a polytunnel or greenhouse. Protect plants from late-season rain and persistent humidity to prevent mould and secure resinous finishes.
