I am planning to build a wooden electric smokehouse using a Venturi smoke generator with a digital temperature controller. I plan to build a 2x4 frame about 3' wide, 2' deep and 4' to 5' tall. My thought is to line it with concrete Backer board and cover over that with aluminum sheeting. Install fiberglass insulation then on the outside cover it with plywood milled siding. First I am nearly complete with my smoke generator but wondering if the aquarium air pump I have purchased will be adequate. Any thoughts on any of this would be appreciated.
