Fruit storage: combo cool room/warm room?
I will be expanding my fruit production in coming years, so I am working on more storage capacity, particularly for apples, pears and pawpaws. I am planning to create a cool room with a Coolbot AC system that has been discussed here. It will be an 8'x8' room lined with blue insulation board. With the extreme low temperatures we are having--many of my apples in storage are now frozen solid--I am hoping to make this cool room also a "warm" room as necessary. Any thoughts about a Coolbot cool room that is also fitted with heat lamps on a thermostat to keep temperatures in the 33-40 degree range during these frigid days? The room will be in an unheated barn.
