Collection: Mushroom Grain Spawn

Our grain spawn is grown on 100% certified organic rye berries. It arrives contaminate free, fully developed, and ready to use. Grain spawn is used to inoculate many bags of bulk substrate quickly, and is the choice methodology for medium and large scale growers. Simply break up the grain spawn well, then transfer some grains to each bag you want to inoculate. The products below are ready to go, however if you have a specific need, please contact us. We would be more than happy to create you spawn for any culture species we sell.
