Three pounds of sterilized and prepared organic rye berries in a gusseted autoclave bag with self healing injection site and air filter patch. Ready to accept mushroom culture to generate mushroom spawn.

Once colonized with mushroom mycelium the rye spawn can be used to inoculate bulk substrates, or transferred to more sterilized grains to expand the mushroom mycelium further. In some cases the rye can be utilized as a direct fruiting medium and grow block.

Sold as single bags for $15, packs of four bags for $49, and packs of ten bags for $99. Choose from the "Number of Bags" drop down box below to receive bulk discounts.
