What is Living Material?:

10 lb bags of our MycoComposite™ material (hemp hurd and mycelium blend) already hydrated and growing for 5 days. Ready to break up, add 3/4 cup of flour, and pack into molds to continue to grow for 5 more days. Because this material is alive, it must be kept refrigerated and used within 2 weeks of receipt.

This is a living material and requires refrigeration and expedited shipping. Save $20 when you buy a case!

Living material shipments are fulfilled Monday through Thursday. We ship this product overnight to arrive the next day to shorten the length of time spent outside of refrigeration. Refrigerate immediately upon receipt until ready to use. Please take into account the 2-3 potential business days when processing orders before shipment and plan lead time accordingly.  Please plan the appropriate lead time.

See our Shipping policy for more information. Only ships to the USA.

Also available by the pallet (100 bags.) For large-quantity orders, please contact us directly at
