I put mine in those foil casserole pans with the foil lids. The psilocybin bible says put substrate in old pillow case and put in a 176 deg F water bath for an hour, then hang dry to field capacity.
Okay, I am thinking the white stuff is just that they are breaking down and I should have plucked them. This evening I will asceptically clean it off, hope most of casing goes, as I shouldn’t have used that, soak it overnight, then see how it does.
This weekend, and maybe tonight we both plan on doing 5 gram trip.
