Coco coir provides many benefits to the mushroom cultivation process. In addition to moisture retention, the porous structure of coir material enables good exchange of air and water and is highly resistant to contaminants making it ideal for mushroom growing. It is often used as casing, added to substrates, and is even used in garden beds as an alternative to peat moss.  

We use it as part of our Boomr Bag substrate blend, and it can also be used as a casing layer in a monotub. If using as a casing layer on fully colonized substrate, it does not need to be pasteurized or sterilized.

Please note that large bags of coco coir are not eligible for free shipping.
