why use mushroom compost? and I never thought of it, might work.
keep everything at 80 or 90 th, mist them once or twice a day.
you threw them out? there are people here who will hunt you down and take your stoner license away for that
maybe they will just kill you.
turn your oven to warm. put your fresh mushrooms on the top rack and prop the oven door open. come back the next day, make sure they are absolutely dry, they should snap if you bend them.
put them in a tight sealing jar. wrap that jar with aluminum foil. put it in the freezer.
now someone,e is going to come along and say you should never bake mushrooms like that because it affects potency.
they will be theoretically right. but throwing them away affects potency more.
and I dont want you to bother yourself with silica gel or fans or threads.
most never notice the difference
