Sour Diesel, otherwise known as “Sour D” or “Sour Deez” is a sativa dominant hybrid with a 90/10 ratio. The origin of Sour Diesel is not completely known, some say it’s a cross between mass super skunk and 91 Chemdog, while others claim that it’s a cross between Mexican sativa and a Chemdog phenotype. Couch lock and a “heavy feeling” aren’t a factor when smoking sour diesel. Instead, you can expect an invigorating cerebral high that open up doors of creativity. This strain is commonly used amongst medical patients to relieve anxiety, depression, and chronic fatigue. Although sour diesel consists of some indicia, it’s not the best strain for insomnia and other similar ailments because of the stimulating and lively head high that it delivers.
