Now available with no quantity restrictions!

Supercharge your bulk mushroom projects with Midwest’s Black Cow Manure Casing Mix, a premium blend of ultra-composted, grain-fed dairy cow manure and carefully balanced additives. This 5-pound fully hydrated casing is loaded with beneficial microbes that speed colonization and help defend against common molds—making it an ideal choice for dung or grain-loving species.

Formulated for Speed and Success:
Our composting process is precision-monitored and heat-optimized (up to 155°F), ensuring nutrient-rich, microbe-dense manure. We then blend it with high-quality Coco Coir, vermiculite, spring water, gypsum, hydrated lime, and a proprietary mineral buffer to create optimal texture and pH for rapid, robust colonization.

What’s Inside:

  •     Grass Fed dairy cow manure (ultra-composted)
  •     Coir (Coco Coir brand)
  •     Vermiculite
  •     Spring water
  •     pH stabilizers: Gypsum, hydrated lime
  •     Special mineral blend (Calcium, Magnesium, Sodium Bicarbonate)

Product Features:

  •     Fully hydrated and vacuum-sealed for convenience
  •     Designed for use with fully colonized spawn bags or jars
  •     Ideal for Monotub and bulk casing techniques
  •     Shelf life: Up to 30 days at room temp (do not freeze)

Recommended Usage:

  •     1 to 1.5 spawn bags per 5 lb casing bag (5-grain or rye)
  •     3 quick-colonizing 24 oz jars per 5 lb bag
  •     6 half-pint substrate jars per 5 lb bag

This may be our most potent mix yet—perfect for mycologists looking to maximize yields in a natural and reliable way.

Perfect substrate

Really good stuff, noticable difference and I found mixing the regular Select bulk substrate with this works just as well! My new "Go to" recipe is 50/50 Black cow and select bulk casing, I always use the regular casing for the top half inch. No contam and I still get the potency increase.

A lot of effort went into this.

This is well worth the money as the mix is sterile and vacuum packed. I could not be more pleased.
