Cultivation supplies for beginners and pros alike

Our mushroom mycelium is grown on certified organic millet or rye grain and is ideal for inoculating the sterilized, or pasteurized, substrates suitable for the species you are growing. It is recommend using your spawn within 4-8 weeks of purchase. Unused spawn should be refrigerated, ideally at 34-36 degrees. One 4 lb. bag of grain spawn will inoculate about 80-100 lbs. of pasteurized straw substrate or 100-125 lbs. of sterilized sawdust.

​​​​​​​If you are wanting to purchase 5 or more bags, or are a commercial cultivator, please call us for wholesale pricing. We have a nearly unlimited capacity to supply you with predictably, consistent, high quality spawn.
