Blackwater Og is an indica-dominant hybrid with strong OG characteristics. Canadian home growers describe it as dense, heavy and suited for evening use.
THC levels typically range from 18-24% in Blackwater Og, placing it among potent mid-to-high THC strains popular in Canada. You should expect noticeable psychoactive effects at standard doses used by Canadian consumers.
CBD usually stays low, under 1%. Medical patients in Canada choose it for THC-driven effects rather than CBD content.
Growing Blackwater Og requires intermediate skill with attention to nutrient balance and humidity. You should adjust practices for Canadian indoor setups and seasonal outdoor windows.
Flowering completes in about 8 to 9 weeks indoors. Outdoor harvest usually falls late September to mid October in southern Canada.
Indoor yields average 400 to 550 g/m² under good LED or HPS light. Outdoor plants often produce 400 to 800 g per plant in warm sites such as BC or Ontario.
Plants stay compact to medium, typically 60 to 120 cm indoors. You should train them for tents or keep them shorter for stealth grows.
Blackwater Og does well indoors and outdoors when you control humidity during flowering. In Quebec, watch for late-season rain outdoors.
Expect deep relaxation, a calm mood lift and sleepiness in higher doses. Canadian consumers often use it in the evening for stress relief and sleep.
Blackwater Og traces to Blackwater x OG Kush genetics. The cross gives OG terpenes and dense bud structure.
These seeds are offered as feminized to ensure high flower counts per plant. MasterSeeds ships seeds within Canada with clear labelling for feminized lines.
Blackwater Og prefers temperate climates with dry summers and mild autumns. It suits BC coastal sites and southern Ontario, while prairie growers should finish plants indoors.
