The Masters Mix Substrate consists of Hardwood pellets (a mix of Oak, Maple, and Walnut) and Certified Organic Soy Pellets, which both provide mushroom mycelium with essential nutrients, and have excellent hydration capacity.
This blend of ingredients (hardwood pellets and soy pellets) is one of the most commonly used substrates in the commercial gourmet mushroom growing world. Masters Mix makes it exceptionally easy to create your own mushroom fruiting block, by simply adding water to the pre-mixed bag, pressure cooking, and mixing with spawn.
This fruiting substrate can be mixed with colonized spawn (like one of our spawn cultures) to form amedium that contains the nutrients and water-retention capacity necessary to produce multiple flushes of large fruiting bodies. You can expect to yield between 1 and 2 pounds of mushroom (Oyster, Lions Mane, etc) by mixing one of our Mushroom Spawn Jars with a whole bag of Masters Mix Substrate.
This product is sold in a Type 14A 0.5 micron filter patch, autoclavable, Unicorn Brand mushroom grow bag.
