Sour Diesel, aka Sour D, is a sativa marijuana strain made by crossing Chemdawg and Super Skunk. Sour Diesel produces dreamy cerebral effects that are fast-acting and energizing. This strain features a pungent flavor profile that smells like diesel. Medical marijuana patients choose Sour Diesel to help relieve symptoms associated with depression, pain, and stress. Growers say this strain grows best in a dry, outdoor climate and has a flowering time of 77 days. Fun fact: Sour Diesel first became popular in the early 1990s and has been legendary ever since.
