Sour Tsunami

Sour Tsunami is a Sativa-dominant hybrid that was first bred by Lawrence Ringo of the Southern Humboldt Seed Collective. After crossing an NYC Diesel with the Sour Diesel strain and back-crossing it with a Sour Diesel clone, Ringo then crossed the resulting genetics, which he named Double Diesel, to a West Coast Sativa-dominant strain called Ferrari. In 2010, Ringo then crossed those genes back with Sour Diesel, and the CBD-rich strain known as Sour Tsunami was officially bred. When grown from seeds, the strain is known for producing several phenotypes, of which about 25 percent will produce CBD-rich flowers. The strain won second place in 2018 for best CBD flower at Colorado’s famed Rooster Cup.
