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. More more detailed information, plese see: Sterilized Rye Mushroom Grow Bag Instructions.

Once colonized with mushroom mycelium the rye berry 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. 

DO NOT alter, tear away, or remove any portion of the attached white filter patch or the plastic shroud covering the injection site. These must remain intact and unaltered to function properly.

A note on rye sourcing: Our raw organic rye berries are secured immediately after the fall harvest and shipped by the ton to our facility, where they are quickly placed into cold storage. This allows us to ensure the freshest, highest quality grains are procured quickly and cared for properly. Grain sourcing is the single most important factor in ensuring quality substrate preparation and sterilization.

Note to local customers: to ensure freshness, most of our sterilized substrates and media are prepared to order. As a result we do not stock these items on our shelves, or place them into cold storage. Rarely, we may have a handful left over from the day's run, but please call ahead of time to ensure we can prepare them for pickup.

Made to order, usually ships within 2-5 days.
