The Blue Dream strain is one of cannabis’ most popular Sativa-dominant hybrids, first coming onto the scene in Northern California, then exploding nationwide as the proliferation of medical cannabis increased. The strain is a perfect example of a Sativa-Indica fusion — combining a selected Santa Cruz Haze mother with a DJ Short’s Blueberry F4 male made this a Sativa-dominant plant, but with the most desirable traits of the Blueberry father intact, including its sweet aroma and large, dense nug structure.
