Eén gedachte over “open air freeschool: running oyster mushroom mycellium on cardboard”

  1. Very cool. Something I’ve been wondering: I’ve been reading about growing oyster mushrooms on deadwood, cardboard, coffee grinds and even on rolls of toilet paper. Should I be concerned that mushrooms grown on chemically treated paper or other media may pass along toxins through the grown mushroom? I’m trying to grow some myself on a straw/coffee grind medium, but am starting with store bought oyster mushrooms rather than pre-grown grain or sawdust spawn. So far it’s going well. Great video!
