As much as I like the metal Hallide idea, I think that 17-1k Metal Hallide lights would cost somewhat more than getting a good heater. Also, I plan to shut the lights off at night

(Ultralux 6-Lamp T5 Fixture w/bulbs).
For the heat, I am liking this Infrared Radiant Heating RSTP: Infrared Radiant Gas Tube Heaters by Space-Ray. I will have to add a propane storage tank, a propane line, and a venting flue.
Thanks all
