I've got a ton of
cardboard.
Should I boil some of it up and place the some king oyster plug spawn in between layers in a plastic container? If this colonizes fully can I break up this block of mycellium into chunks and place it in between layers of pasteurised cardboard in a laundry basket in a dark room?
Any other tips? Will this produce many king oysters or should I add some pasteurized hardwood chips in the laundry basket as well?
