Mushroom Casing is the last layer of media in commercial mushroom growth. Peat is used as it will hold 10 times it's own weight in moisture, and mushrooms thrive in this environment. Casing is a natural environment for mushrooms to grow in. Casing also gives the mushroom a vibrant natural color which many other media do not give. Mushroom casing consists of a blend of wet peats which are neutralized. There are many different mushroom growing systems throughout the world, from mushroom bag growing systems, mushroom tray systems and Mushroom Shelf systems. What all theses mushroom growing systems have in common is they all use Mushroom Casing Soils.
