A3 medium coarseness is ideal for mushroom cultivation, as it has greater water retention capacity and can be used for external casings.
Ideal for use in cake-style, manure-based, and straw-based mushroom cultivation methods.
A thin layer can be added to the base of a fruiting chamber to increase ambient humidity.
OMRI Certified – product can be used in certified organic operations under the USDA National Organic Program.
