What type of bag should I use for a humidity tent?

Use a large plastic bag with plenty of 1/2 inch holes or slices placed in it. We use a pair of scissors and cut some slices into grocery store bags or large produce bags. It can be helpful to have a clear or semi-transparent bag to keep an eye on the progress of our mushrooms. You may choose to use a plastic basket as a frame for the bag or get creative with ways to prop up the bag if it's not thick and stiff enough to hold on its own. Spray the inside of the bag daily to create a humid home for your mushroom kit.
