Blackwater OG is Cali Connection’s brooding, purple-leaning take on the OG family, created by pairing Mendo Purps with SFV OG Kush (their feminized seed line uses Mendo Purps x Tahoe OG S1 while keeping the same dark-kush intent). Expect stocky plants with dense, trichome-frosted flowers that wash from deep forest green into moody violet, carrying a classic grape core laced with lemon and pine. Myrcene, caryophyllene, and limonene drive that profile. Typical lab results put THC around 17–20% with trace-to-low CBD, and the effect lands squarely in the indica camp: a heavy, body-first calm that trends sleepy and often stokes the munchies. Indoors, Blackwater OG finishes in roughly 56–63 days and performs best with simple training; experienced growers report medium stature and generous yields around 500 g/m², while outdoor plants can top 2 m with about 600 g per plant by late September to early October in temperate climates. The cultivar’s visual drama and syrupy kush aromatics helped it claim 3rd place Best Indica at the 2014 High Times Medical Cup in Los Angeles.
