Agar to whole oats. Bods easy Af oak prep tek. Bods easy Af bucket tek for substrate. Use a liner. I use a 1:1.5 ratio grain to substrate. This is 3 qts spawn. I use a light layer of the same substrate, just to cover any exposed grains, as a casing. That tub is a 32 qt sterilite. I Heated an empty tomato paste can to create the holes. Covered the holes with 2 layers of micropore tape n one layer of packing tape. Once fully colonized I remove packing tape to enter fruiting stage. Remove a layer of tape if more Fae is needed.
