Origin #1

303 OG, also called 303 Kush or 303 OG Kush, is reported to have first been cultivated in Colorado by the breeder known as Zombo and is an Indica-dominant cross between a Pre-'98 Bubba Kush and Reservoir ChemDawg IC3.

Reported by online sources to have been selected for its phenotypes by Colorado’s Hill Billy, the strain was named after Denver’s area code. Clones are the best option for cultivators looking to grow 303 OG, as seeds are not easily obtained.

The 303 OG grown by The Clinic in Colorado is an Indica-dominant cross between Kosher Kush and Ghost OG. Available throughout Colorado, flowers from The Clinic’s 303 OG strain provides a sweet and spicy flavor profile that’s popular for its OG characteristics, powerful body high, and cerebral effects.

The Clinic’s 303 OG Nug Run Sugar Budder won first place in 2014 for Best U.S. Concentrates at the Denver High Times Cannabis Cup. The Clinic’s 303 OG THC content has been tested as high as 20%, and the strain reportedly helps mitigate physical discomfort, apprehension, insomnia, and loss of appetite.
