You are ordering 20lb of the very same hardwood (oak) fuel pellets that we use for our work. This will arrive in a bag, within a USPS flat rate box. Oak is considered a universal donor for most wood loving gourmet mushrooms that are commonly cultivated. This substrate works great unsupplemented and can be pasteurized.

If you prefer to supplement your substrates to see increased yields, you can add supplement like wheat bran, alfalfa pellets or other nitrogenous agricultural by-products to about 20% (5% for shiitake). Keep in mind that substrates that are supplemented MUST be sterilized.

Order 100lb and save 15%! The discount will be applied when the product is added to the cart.
