I am having a hard time balancing temps still. I don't like drastic temp changes. What are others doing to maintain temp in the Southland? It is easier with the 1000w HPS bulb.

Room 12'x16' (Will enclose smaller after harvest)
Cooltube (Duct to attic is completely off right now to maintain temp)
1000W MH conversion bulb for HPS socket. (Runs really cool)
Box Fan in window with an A/C vent to block the light. Minimal actual pull from box fan maybe 200CFM makes it through.
House Central Heating is partially open at night.

Pointers that could tighten this up without spending a lot of $? I can put a space heater in there but what kind of $ for elec am I looking at and will I need to bring in another ext cord? Too much amps?
