Sour Tsunami is a strain that became famous for being one of the first to be especially bred for high CBD as opposed to THC content. The end result is a strain that’s effective at treating pain and inflammation without producing a significant “high” that is linked to high thc. Sour Tsunami cbd levels test as high as 10 or 11%, while THC is generally under 10%. Lawrence Ringo of the Southern Humboldt Seed Collective swallowed this strain over four decades of hard work by crossing Sour Diesel plants with NYC Diesel. This sativa-dominant hybrid flowers within 9 weeks, making dense green buds with dark purple-tinged and green leaves. The buds have a familiar musky diesel odor with sweet undertones.
