5lbs Masters Mix

This premium masters mix is a professionally formulated, sterilized bulk substrate designed to maximize yields and accelerate mycelial colonization. Crafted from a nutrient-rich blend of hardwood sawdust, soy hulls, and select substrate amendments, this mix provides the perfect foundation for growing gourmet mushrooms. The result is a superior nutritional profile that promotes faster colonization and larger, healthier fruiting bodies—all with a pleasant, leafy, deep veggie aroma, thanks to our high-quality soy hulls.

Whether you're cultivating oyster, lion’s mane, shiitake, or other gourmet varieties, this masters mix is the ideal choice for creating fruiting blocks. Use it in conjunction with any of our grain spawn strains for robust growth and high yields. This bulk substrate is perfect for fruiting directly from the bag in a controlled setup, such as a Martha tent or monotub, making it a versatile and reliable option for home and commercial mushroom growers alike.
