Pre-Pasteurized Mushroom Compost - 5 lbs.

Pre-pasteurized premium bulk substrate mushroom compost (5 lbs.) in a gusseted autoclave bag with filter patch. Gourmet Mushroom Supply mushroom compost is specifically formulated for growing mushrooms. It is free of any additives or chemicals and is to be used in conjunction with our mushroom grain spawn.

This choice bulk substrate is composed of five main ingredients including an organic compost specifically designed for mycological use, composted horse manure, organic coconut coir, vermiculite, and gypsum. This diverse blend of unique ingredients provides the perfect amount of nutrition for optimal mycelial growth, making it the ideal growing medium for mushroom cultivation.

Our premium mushroom compost comes pre-pasteurized and hydrated to the perfect moisture content, making it ready to use right out of the bag. Simply add colonized grain spawn, mix, and add to your fruiting chamber or grow bag. We recommend using two pounds of our grain spawn for every five pounds of compost. Once the substrate is fully colonized with mushroom mycelium, our casing mix can be applied in a thin layer to the top of the substrate. Please note that a casing layer is not required, but rather an optional ingredient that can benefit the growth of certain mushroom species.

This product comes heat-sealed in sterile, filter-patch mycobags and can be stored at room temperature for up to 14 days. If more time is needed, it can be stored in the freezer and dethawed before use.

All mushroom compost comes packaged in 5 lb. increments.
