Dehydrated Horse Manure


Phillip K.
Ordered 5 gal. Was sent out fast and arrived double bagged in a box well sealed to insure safe delivery. I broke it down into smaller storage bags and its great quality. No big chunks to break up. Doesn't smell if that's what's preventing you from trying this in your substrate. I will post another comment after I'm ready to use this and colonized. But I'm sure it will be the best I've ever used. Thank you Shroom Supply

Super fast shipping and just what I need thank you . Peace and good fortune!

All the difference Ive been looking for, heavy pinning and huge fruits. leached and composted correctly, fluffy with no smell. If your HM isn't dry and fluffy, it hasn't been composted correctly. Plus from organic fed horses, so no worries about fungicide contamination!!!!

This horse manure is the best I have found to date. We form patties for multiple use as we have a restaurant that serves mushroom burgers .We will be sure to tell our friends about this excellent product.

Wow!! This is most deff top quality HPoo!! Thank you ShroomSupply for always carrying the best of the best!!!

This stuff rocks!! I use it as an additive to a coir sub or just straight with some verm and I get great yields! Also Ryan was nice enough to help me get the moisture right by E-mail. Great product, great customer service!!

I must say that you guys have made a great first impression with me. The last batch of horse manure I ordered from somewhere else (I won't mention where) arrived at my door with a strong smell of ammonia and ROCKS in it. It was obviously NOT field-leeched like they claimed... nor was it even sifted for LARGE ROCKS. This stuff is exactly what it says it is... PREMIUM POOP. It doesn't smell at all and is of great quality and consistency... 100% dry. Thank you guys.

Excellent product. Giant MIND-BENDING flush off this stuff. Looking forward to my next order's arrival.

This product is the best quality horse manure I have personally been able to find. I've ordered from a couple of other places and this is the best. It already comes shredded so you don't have to worry about figuring out how to chop it up. Will be ordering again.
