303 OG Kush carries Denver’s area code and two different Colorado origin stories.
Origin 1: Colorado breeder Zombo is credited with crossing Pre-98 Bubba Kush with Reservoir’s ChemDawg IC3. Hill Billy reportedly selected the standout phenotype. This indica-dominant version also circulates as 303 OG and 303 Kush, though its potency and sensory profile remain sparsely documented.
Origin 2: The Clinic in Colorado identifies its 303 OG as a cross of Kosher Kush and Ghost OG. Sweetness and spice define this version’s flavor, backed by the pungent character associated with its OG lineage. Flower has reportedly tested around 20% THC. The Clinic’s 303 OG Nug Run Sugar Budder took first place for Best U.S. Concentrates at the 2014 Denver High Times Cannabis Cup, an award for the extract rather than the flower.
303's loyal following reports The Clinic’s version as physically heavy with a pronounced cerebral component. That combination gives its OG reputation some substance, although those accounts should not automatically be applied to Zombo’s separate cross.
Zombo’s 303 OG has historically circulated through clones, with seed availability described as limited. Specific flowering times, yields, and growth characteristics are not established in the supplied information for either version. Cultivation details should stay tied to the identified breeder and cut.
