Blackwater OG is a hybrid strain that comes from a cross of Mendocino Purps with SFV OG Kush. People who try it most often describe feeling sleepy, hungry and relaxed.
Across 211 public lab tests of Blackwater OG flower between 2020 and 2022, the median result was 25.9% total THC, with half of all samples falling between 23.7% and 28.2%. CBD is typically negligible (under 0.5%). That puts it at the strong end of the market, so newer consumers should start low. Potency varies by grower and batch, so always check the label.
In lab tests its dominant terpene is myrcene, followed by caryophyllene and limonene. Myrcene is known for earthy, musky notes with a ripe-fruit edge, while caryophyllene adds black pepper and warm spice. Total terpene content measured a median of 2.2%. On the palate, people pick out chemical, blue cheese and berry.
Beyond feeling sleepy, reviewers also mention feeling giggly and happy. Some consumers say they reach for it when dealing with anxiety, insomnia and lack of appetite. The side effects mentioned most are dizziness and dry mouth. These are personal reports, not medical advice.
Parents: Mendocino Purps and SFV OG Kush.
