Sour Tsunami by SoHum
When you're talking about the genesis of the modern CBD movement, you have to talk about Sour Tsunami and the late, great Lawrence Ringo. Back around 2010, way before the mainstream caught wind of CBD, Ringo was up in Northern California testing his SoHum Seeds (Southern Humboldt Seed Collective) gear. He took a classic Sour Diesel and crossed it with NYC Diesel, eventually hunting down phenotypes that pumped out massive amounts of CBD instead of the usual THC heavy-hitters. This wasn't some corporate lab project. It was a dedicated breeder looking for real medicine, and what he found ended up laying the foundation for legendary crosses like Harle-Tsu and Canna-Tsu.
If you were kicking around ICMag or Rollitup during the early 2010s, you remember the wild rush for these genetics. A lot of old heads respected Ringo for prioritizing healing over pure cerebral blasts when the whole market was just chasing higher THC percentages. But with that hype came the inevitable knockoffs. Rollitup threads from that era are packed with warnings about fake SoHum seeds floating around NorCal dispensaries—guys thought they were popping authentic Ringo gear and ended up with industrial hemp or unstable hermies. Finding the real, verified Ringo cuts became a serious hunt.
Growing the authentic Sour Tsunami is a trip. The plants retain that signature Diesel structure—stretchy, vigorous, and needing decent support late in flower. When you get a solid phenotype, the terpene profile is this unmistakable mix of musky earth and sharp, astringent diesel gas, totally unlike the sweet or fruity CBD strains that came later. It's a genuine piece of cannabis history. Ringo's passing in 2014 hit the community hard, but his sons and dedicated growers have kept the authentic lines alive, making sure that genuine Sour Tsunami still has a place in the garden.

Growing Sour Tsunami: what to expect
As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with Sour Diesel or ACDC will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
