Jude: My guess to why an air conditioner is not feasible is the cost. In some places the cost of utilities is much greater than what we pay here in the Northeast.

Set it at 80 (or whatever) and forget about it? I turned a historic barn/garage into my plant house with 2 inch thick rigid pink foam boards on the walls, and doubled up (with air space between the layers) in the ceiling. I have not even needed to turn my heater on yet this winter because the lights generate enough ambient heat to keep it where it's comfortable. I agree this is a fantastic thread.
