Winter Rye Grain Spawn Bags

Our Winter Rye Grain Spawn starts with locally sourced seed, carefully soaked, boiled, and sterilized before being inoculated with aggressively colonizing mycelium. Heat-sealed for freshness and shipped ready to run — use it to inoculate bulk substrates or generate second-generation spawn bags for larger grows.

Master Mix Substrate Blocks

Skip the prep work. Our 5 lb Master Mix Blocks combine hardwood sawdust and soy hulls in a proven, high-yield substrate — sterilized, sealed, and ready for your grain spawn. Just inoculate, mix, and watch your mycelium take over.

Fresh Agar Plate Cultures

Our agar plate cultures are grown on sterilized potato dextrose agar (PDA) in crystal-clear polystyrene petri dishes — built for durability and easy handling in the lab.

Every plate is made to order using strict sterile technique in our in-house laboratory, ensuring you receive the freshest, highest-quality cultures possible. Each culture can be used to inoculate grain spawn or bulk substrate bags, produce liquid cultures, or generate additional plates to expand your library.
