I like it! I'm going to steal some of your ideas for my own hood. I'm finishing the doors for my stand right now, putting them on tomorrow or Friday. I'll post finished pics soon.
Then the only thing left on this tank is building a hood, which will be nice fiinished wood. Questions for you -
1. How much did the MH
cost? I like the setup.
2. Did you paint the inside white to reflect light?
3. Are you going to wire a surge-protector and timers into your hood, or have that external?
For fans... I have this thought about using an old computer power supply, and computer fans like the pic below. You can get big "stealth" fans (meaning VERY quiet) for $10 each. If I go that route I'll send you pics of the wiring, etc. It'd be more compact, and easy to wire.
