Discover the best bulk mushroom substrate available, meticulously crafted to cater to manure-loving mushroom varieties, and engineered for superior growth yields. This premium mixture combines composted manure, coco coir, and vermiculite, precisely balanced with optimal moisture levels.

Exclusive to Eastcoast Mushrooms, our product includes a separate bag of TOP CASING LAYER. This layer serves multiple purposes: it enhances yield, safeguards your colonised substrate, fosters a humid microenvironment for mushroom primordia development, and nurtures beneficial microorganisms.

Assuming all other growing conditions are met, these four advantages synergize to create an optimized environment, ensuring maximum mushroom yield. You can utilize this exceptional blend in monotubs, outdoor beds, or for cultivating mushrooms directly from the bag in a controlled humidity grow room or a Martha setup!
