If your interest is in controlled “grow room” style cultivation on sterilized or pasteurized substrates for maximum yields, consider beginning with our 8-Block Sets to test your mushroom growing thumb (or would that be “brown thumb”?) All blocks arrive ready-to-fruit and come with instructions to guide you along the fascinating challenge of ramping up mushroom production. The sets are packaged in quantities of eight to allow for the best pricing in shipping and handling. All are certified organic grown on wood from Wisconsin hardwoods. It’s best to fruit them indoors initially, after they seem spent, put them outside in the spring/summer/fall and collect a few more harvests! Our 8-Block Sets are available in Shiitake, Oyster, Lion’s Mane, and Reishi and can also be ordered as a mixed set.
