Mix Strawberry Kush (Sour Bubble, East Coast Sour Diesel, and Strawberry Cough) and Razzberry, and you get the award-winning Sour Strawberry (aka Sour Strawberry Kush), a fruity indica-dominant hybrid with an unknown sativa/indica ratio. Strawberry, berry, and other fruit are the dominant notes in the musky aroma and flavor of this strain, which also produces pungent hints of Kush and diesel fuel.
Sour Strawberry placed 8th in California's Emerald Cup 2013, in large part due to its massive THC levels, which can exceed 25%. But it's low in CBD content, much too low to recommend that patients use it to treat epilepsy or other conditions that respond to CBD concentrates.
Instead, this strain is recommended for the treatment of mood disorders and anxiety, as well as depression.
The high is both cerebral and physical, with a euphoric body buzz and happy psychoactive effects. Despite its esteemed pedigree, Sour Strawberry isn't widely available, though it seems to be fairly popular in places where it is sold. That mostly includes California, though this strain may occasionally appear elsewhere in the American West.
