About Sour Tsunami
Sour Tsunami is a historic medical cannabis breakthrough developed in Southern Humboldt County by the late pioneer Lawrence Ringo of the Southern Humboldt Seed Collective. Frustrated by severe spinal pain and seeking relief without overwhelming psychoactivity, Ringo spent over four years selectively backcrossing Sour Diesel, NYC Diesel, Ferrari, and Lawrence OG to stabilize high cannabidiol (CBD) production. Sour Tsunami produces dense, forest-green colas with a pungent aroma of sweet sour diesel, pine needles, earthy musk, and citrus. With CBD levels consistently testing between 10% and 14% alongside 6% to 10% THC (often achieving a balanced 1:1 or 2:1 ratio), Sour Tsunami delivers powerful anti-inflammatory, pain-relieving, and anti-anxiety benefits with a crystal-clear, functional head.
