Sour Diesel is a 60/40 sativa-dominant, legendary ‘90s varietal. The popular cultivar is rumored to trace back to Grateful Dead Tour circa 1991. The legend goes that a bag of Chemdawg flower with 13 seeds in it ended up making its way to Massachusetts, which spawned Chem 91, Chem Sister, Chem C, and Chem D. From there the story unwinds, with reports that Sour Diesel resulted from an accidental cross of Chemdawg with Super Skunk, Skunk #1, or Northern Lights by a young NYC grower named AJ who acquired the new Chemdawg cultivar while attending a popular local concert venue. Voted High Times Magazine’s third-best strain of all time, the Sour Diesel is known for its pungent ‘diesel/gassy’ profile that produces heady, cerebral, and euphoric effects.
