High Mountain Compost – mushroom substrate, kits, kit refills, compost tea
10lb filter patch bag of mushroom growing compost
We sell a rich, natural, manure based growing medium, specifically formulated for growing exotic, gourmet and medicinal mushrooms. It is odorless and easy to use. No casing is required.
Because it has been heat pasteurized, you can use it without worrying about contamination from the compost.
It is not the “mushroom compost” you can buy at a garden center, which has little or no mushroom nutrients and a generally high salt content. It is not the “mushroom compost” you often see advertised. That “compost” has already commercially produced 3 harvests and is considered ‘spent’.
Our compost, packaged in 10lb filter patch bags, has been specifically formulated for dung-loving mushroom growth, and is by far the most nutrient rich substrate available. It will last for an indefinite amount of time as long as the bag is kept sealed and in a cool(50-55 deg), dark place, like a refrigerator.

the mushroom compost is subject to airborne contamination.
