We recommend using Sawdust Spawn for larger mushroom log projects or if you plan on inoculating logs every year as it is cheaper than plug spawn. One bag of Sawdust Spawn will reliably inoculate 20 logs and costs at most $25 per bag (we offer bulk discounts on 4 or more bags). This allows the cost of the tools required for using Sawdust Spawn to be quickly offset by the cheaper priced spawn if you plan on making mushroom logs every season!
Note: You will need an Inoculation Tool to inoculate logs with Sawdust Spawn. An Angle Grinder Adapter and specialized 12mm drill bit can also make inoculating more efficient. Save money by getting our 'Trio of Tools" bundle.
North Spore sawdust spawn is produced in our vertically-integrated facility located in Westbrook, Maine. Production is overseen by a team of expert mycologists, lab technicians, and seasoned mushroom spawn production specialists. We start the process by taking mushroom cultures from our own culture bank and growing them out on a blend of organic millet and wheat berries. (And many of our cultures were isolated and grown from wild mushrooms foraged in New England!)
