Developed over the last 35 years using organic and sustainable practices in Southern Humboldt County by Lawrence Ringo and his sons. On a great "hook up" Lawrence ended up in Humboldt in the late 70's. Two years later he got on a piece of land and started breeding his favorites and mixing them with the new strains his buddies brought from around the world. Over the years Lawrence created one of the most respected seed banks in the world. Lawrence dedicated his final years of life stabalizing several strains of high CBD genetics and training his 3 son's to follow in his foot steps...
