Oyster Mushrooms that is. Dave started these mushrooms indoors in a cardboard box. Alternating layers of mushroom spore and wet straw were packed into the box and it was stashed in a dark closet for a month. Mycelium formed throughout the box and when it was moved into the sunlight the mushrooms emerged.
Mushroom spore are sprinkled in the box
Then damp straw is added
Once moved to the sunlight the mushrooms quickly fruit
They find the openings and weak spots in the box
