    Mushroom substrate 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!

    Midwest's Premium Select Bulk Substrate is the perfect combination of Coco Coir, Vermiculite, Hydrated Lime, Gypsum, ph buffers, ph stabilizers, mineral water and a few other choice ingredients. Our select casing comes fully hydrated and pasteurized and is ready to use right out of the bag!

    • Our Grower's Select Monotub
    • 30-44 Quart Size Containers
    • Shelf life of up to 6 months!
    • Fully Pasteurized and Ready to use!

    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.

    Pros:
    • Size
    • field capacity
    • delivery
    Cons:
    • None
    Always trust this company and their products. Saw they have a larger 7.5lbs option than the original 5lbs. This substrate is always delivered fast and in good condition. Field capacity is on point and added nutrients improves colonization. Put my grains to to bulk and within 24 hours had vigorous growth and fast recovery.

    CVG substrate.
