Mushroom Compost

After our mushrooms fruit, the remaining substrate is no longer commercially viable for mushroom production but can still be used in a variety of ways. Although, this compost will continue to produce quality mushrooms. This is spent mushroom substrate or “mushroom compost” and is made of sterilized and supplemented sawdust that has been broken down by fungi.
