I love the mushroom farm box idea, @jvls1942 ! I may have to talk DH into growing 'shrooms this summer in the concrete "bunker" on the farmstead. We are going to try to make the necessary adjustments to make it a working root cellar by next winter. That probably means by winter of 2018 ... so many projects for this summer already.
He was talking about starting some mushroom logs this summer - a co-worker was talking about how his son grew mushrooms and sold them to a lot of the restaurants in the area. I suggested to do it behind the machine shed. The morning dew will drip onto them in the morning and they are on the north side of the building - so a nice shaded area. I talked about growing mushrooms about 2 years ago when we moved onto the place, but he felt at that time that it was a stupid idea.
