Full Cannabinoid, Terpene, Effects, Medical, Flavor, Aroma, Potency, Grow & Cultivation Breakdown
Overview
OG Kush THCa flower is one of the most iconic and influential indica-leaning hybrid cannabis strains in the world, revered for its pungent earthy-gas aroma, powerful euphoric effects, and deeply relaxing body calm. Often regarded as a foundational strain in modern cannabis genetics, OG Kush has shaped countless hybrids and remains a gold standard for potency, flavor, and effect balance.
