North Spore produces 100% of its spawn at its facility in Westbrook, Maine. Spawn is used by mushroom growers much like seeds are used by gardeners and vegetable farmers. It is the genetic material used to grow mushrooms.
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 $20 per bag (we offer bulk discounts on 8 or more Sawdust Spawn 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!
*You need an Inoculation Tool to use Sawdust Spawn! For larger projects you may want to purchase an Angle Grinder Adapter and specialized 12mm drill bit! or save money by getting our 'Trio of Tools' deal
