I just had a crazy idea. I am looking to build a root cellar, but I have a huge pantry (walk in closet size) in my 1st floor kitchen. Do you think if I insulated the door and drilled a hole straight through to the outside for a vent system it would stay cold enough in the winter? I have looked at plans, but I don't know if having it outside the basement will work. The pantry is always a little cooler than the kitchen anyway, but not root cellar cold. Has anyone heard of this being done??
