Sour Diesel, otherwise known as "Sour D" or "Sour Deez" is a sativa dominant hybrid strain with a 90:10 sativa/indica ratio. The origin of Sour Diesel is frequently debated within the marijuana community. 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. Either way, you can undoubtedly look forward to a high like no other. 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.
