Shredded Horse Manure for Mushroom Substrate – Sun-Cured (Shipping Included)

About this manure

This shredded horse manure is sourced from Texas and naturally sun-cured, which reduces odor and gives it a fine, dirt-like texture that mixes evenly into bulk substrate. It’s meant for DIY growers who mix their own manure-based substrates, such as CVGM.

It is raw: not sterilized or pasteurized. Pasteurize it along with the rest of your substrate before use.

• One USPS Large Flat Rate box, packed full (roughly 10–15 lb)
