I added one bag of the wild horse manure booster with 1 bag bulk casing mix & 3 24oz fully colonized jars. Substrate 85% colonized at day 7!!!

This booster is the best by far!!! Amazing results. Bulk trays colonizing super fast. Must use with recommended casing mix. Shipping was super fast as well. I will always be back for more. Keep up the great work!

I tried the horse manure mix a few months back and now I will never go without, the results was amazing and the mushies loved it, it’s the perfect mix, It’s like a booster for them, I it way better fruits when adding this to my mix.

This helped so so sooo much in growing my mushrooms. I’ve never had such a big yield. I will always be using this from now on. Thanks Midwest!

Fast shipping, good product
