    Mushroom substrate or casing is moisture retaining medium to mix with grain spawn when growing in containers, trays, totes or "monotubs". This method is generally referred to as the "Bulk" method or "Monotub Method". This is the most popular way to fruit your spawn bags or whole grain 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!

    Use the following amounts:

    • 1 Spawn bag per 5 lb bag of casing mix (using our 5grain or Rye spawn bag)
    • 6 Jars per 5 pound bag of casing mix (using our 1/2 pint substrate jars)
    • 1 32oz Grain Jar per 5 lbs
    • 2 24oz Grain Jars per 5 lbs
    • Shelf life of up to 6 months!

    Our Select Bulk Casing Substrate is guaranteed to arrive with the perfect amount of water often called "field capacity". All you do is open the bag and mix! We have spent years slowly perfecting this recipe to what it is today. We use only the best quality ingredients and  unique additives to provide a consistent, reliable product with the highest ability to resist molds and contamination.

    Our Select Bulk Substrate has the highest level of mold & contamination resistance!
    We use specific ingredients that create a mushroom friendly substrate that resists mold and bacteria better than any other brand we have tested. We pasteurize, not sterilize. The lower temperatures help retain the natural anti-microbial properties of coco coir that keep mold and bacteria issues away.
