Thanks Char, right now I am alternating from CFL to MH. When the MH gets too hot and the A/C stop working so well, I turn A/C to fan mode to defrost the inner piping to allow better airflow and to dry up condensed water, while this is happening I use the CFL's to ensure I won't have heating problems, then when A/C is back to blowing frigid air, I turn MH on, and steady 77 degrees throughout

When I get the cooltube I will need to make a hole somewhere in the closet (6 inches for exhaust) not sure if my landlord will like it but that's a chance I am willing to take, since it is after all, just a closet. I will obviously plaster it when I leave to make sure there is no crazy holes in the walls but for exhaust I need to do something, right?
