303 OG Kush

The name 303 OG Kush, also known as 303 OG or 303 Kush, refers to two different Colorado origin stories. The first version is attributed to the breeder Zombo, who crossed Pre-98 Bubba Kush with Reservoir’s ChemDawg IC3. A standout phenotype of this cross was reportedly selected by Hill Billy. This version is considered indica-dominant, though its specific potency and sensory characteristics remain sparsely documented.

The second version, associated with The Clinic in Colorado, is a cross of Kosher Kush and Ghost OG. This iteration is defined by a flavor profile of sweetness and spice, supported by the pungent character typical of its OG lineage. Flower samples have reportedly tested around 20% THC. While the flower is well-regarded, this version gained notable recognition when its Nug Run Sugar Budder extract took first place for Best U.S. Concentrates at the 2014 Denver High Times Cannabis Cup. Users of The Clinic’s version report a physically heavy experience accompanied by a pronounced cerebral component.
