Coco coir is a non-sterile substrate that provides many benefits to the mushroom cultivation process. In addition to moisture retention, the porous structure of coir material enables excellent gas exchange, water supply, and is highly resistant to contaminants. It is primarily used as a casing layer in monotubs or as a substrate additive. However, it can also be used in garden beds as an alternative to peat moss.

How to use:

Coco coir should only be added to fully-colonized substrate covered in mycelium with pins beginning to form. Only a thin layer of coco coir (1/4 to 1/2 inch) is necessary.

Pasteurizing coco coir:

Coco coir is naturally resistant to bacteria. However, some users prefer to pasteurize it. Should you choose to do so, we recommend steam pasteurization or a water bath at 180 degrees for 1-2 hours. Once pasteurized, squeeze out excess water and allow to dry before use. (Latex gloves recommended.) 

About coco coir:

Coco coir is made from coconut husks, is biodegradable, and is a 100% renewable resource, It also has traces of Magnesium, Calcium and Nitrogen that contribute to the growth of mushrooms. 

Storage:

Coco coir is best stored in a cool, dry place. Because it can easily absorb moisture, we recommend storing in food-grade, air tight containers.

Please note that 30 lb bags of coco coir are not eligible for free shipping.
