How do you grow psilocybe mushrooms?
I never use vermiculite for that. Use spagnum Moss inside the nest box. the vermiculite is for incubating the eggs in.
I personally use perlite for my boxes
Prepare a laying box with 1-2 inches of damp perlite or vermiculite.
make a nest box with vermiculite in it. basically a plastic box about twice her size with a hole cut in the top for her to come in and out of. make sure its damp to the touch. not wet at all, just damp
