    Mushroom Casing (substrate) is a non-nutritious moisture retaining layer to spread on the top and bottom of your mushroom substrate. This method is generally referred to as the "Bulk" method, Monotub, or Bulk Substrate. this is the popular alternative way to fruit your spawn bags or jars. We provide easy to follow instructions on how to use and create your bulk grow. The hardest part of this process is achieving the perfect ratios of substrate, casing and water. We've made it easy! Perfect for grain or dung loving mushrooms!

    • 1 Spawn bag per 5 pound bag of casing mix (using our 5grain or Rye spawn bag)

    Inoculated 2 of the 5 pound rye spawn bags, and used 3 of the 5 pound casings for my bulk grow. Casing had an incredibly healthy, earthy smell.
    No issues whatsoever, and the mycillium started showing through in just two days! After just 6 days, I had 100 percent growth and they started pinning on day 7! Highly recommend
