Southern Humboldt Seed Collective

Southern Humboldt Seed Collective is a private California cannabis genetics and seed company associated with the late breeder Lawrence Ringo, a pioneer of high-CBD cannabis cultivars. The company appears to commercialize cannabis seeds and clone genetics rather than developing regulated human therapeutics, with offerings centered on breeding, seed sales, and legacy medical-cannabis strains. Publicly available sources link the business to Whitethorn in Humboldt County and describe it as operating as Southern Humboldt Seed Collective, LLC. Its best-known genetics include CBD-focused cultivars such as Harle-Tsu, Sour Tsunami, and Ringo's Gift. From a biotech classification perspective, it is better characterized as a cannabis breeder/seed business than as a pharmaceutical, biotech, or healthcare company.
