Our raw horse manure is a great start for making your dung loving mushroom substrate. Our horse manure is field aged for two years in gigantic rows so there is no typical manure smell. You will need to add your own adjuncts and pasteurize accordingly. See our other listings for ready to use substrate mix.
This listing is for a large priority mail flat rate box stuffed as full as we can get it, approximately ten pounds but the weight will vary due to moisture content.
