Join our team as we go Beyond the Market to Mushroom Adventures! Located in Marysville, a quaint town in Yuba County, California, Mushroom Adventures is a small, certified organic indoor mushroom farm. Don Simoni, the founder, and owner guides us on an exclusive tour of his operation and explains how mushrooms reproduce, grow, and are harvested. Don originally started growing mushrooms as a hobby, then eventually he started making and selling his individual grow kits; fast forward more than 20 years later, and Mushroom Adventures has expanded into growing a wide variety of mushrooms to sell in multiple California farmers' markets. They specialize in portabella, shiitake, white button, oyster, and crimini mushrooms. Find them at a farmers' market near you!
