This stuff never lets me down

This Was My First Order From Midwest, I Order 4 Of The 5-Grain Jars And 2 5lb Cow Manure Bags. The Jars Were Fully Colonized In 23 Days , I Moved 2 Jars and 1 5lb bag of manure to bulk to test it out. Its Only Been A Few Days And The Tub Is Colonizing Prolificly! Im Very Satisfied With This Product And Will Be Using Again. Lol Hopefully I Can Get A Sponsor For My Channel. Great Field Capacity And Shipping Time. Only Took 1 Day To Ship And 2 Days To Arrive. 5 STARS !

Black Cow Manure Bulk Substrate is with out a doubt the best medium that I have used for my growing. Mycelium growth in less than one week from planting. Fantastic yield. 100% recommended for your bulk growing.

I recently ordered this product for a second time. I was really impressed with the results of using this casing mix first time around. And as always received my order quickly and packed nicely. I would definitely recommend this product for anyone wanting to boost their grow!

I mixed the mycelium from the Premium Quick-Colonizing 5 grain jars with the Black Cow Casing mix. In two days I started to see white mycelium growing on top. The entire top of the casing mix was white in 7 days! This stuff is amazing! It's now been 15 days and I am starting to get many pins and several mushrooms growing. This casing mix is the best on the market. I will buy nothing else in the future.
