5lb block of sterilized oak sawdust

This is our block recipe for wood loving mushrooms. This block consists of hardwood sawdust with gypsum that is hydrated to holding capacity, bagged in a filter patch bag and then sterilized. We do not supplement our hardwood bags because in our experience we achieve better supplementation when we use about 1-1.5 cups of rye spawn per block. When using extra rye spawn as supplementation we find it colonizes faster and has larger fruits.
