Visit our website to view an accurate inventory of our Grain Spawn species.
Grain Spawn is used for almost all commercial indoor mushroom production.
*Only some species of Grain Spawn will work in outdoor straw, wood chip, or compost beds. When this method is applicable, it will be listed under 'Inoculation Methods' in the species descriptions.
Indoor Commercial Production- For species in the Oyster Mushroom family, grain spawn can be mixed into sterilized or lime pasteurized substrates including but not limited to hardwood sawdust, straw, and coffee grounds.
For most other species substrates need to be cooked and sterilized in a steam tank or autoclave. These processes range from requiring a fair amount of infrastructure for larger projects to simple and low-tech for Oyster Mushroom species.
We recommend purchasing a book on mushroom cultivation if you are interested in indoor cultivation as a hobby or profession.
