Whats the ideal setup here?

i have a 4x4x7 DR 150 and going to fit it with a 600w hps.

was thinking i would have to do something like this

-2 / 4" CanFan/Vortex fans for intake/exhaust with compatible filter
-1 / 6" Can or Vortex for the 600w Air Cooled Hood


I know the duct hose is going to run in from the left side, through the reflector, and out the right side, but thats all i know.

Ideally how should I have things setup in the tent? Where should I be pushing air and where should I be pulling it in relation to fans/filter/reflector

I remember seeing a few good sketches on here before but for some reason i can't find them now

Hey, I ran a DR100L with
-400w Air-Coolable Reflector
-6" 435cfm Valueline Fan

I also had, but didn't use:
-4" 171cfm Valueline Fan
-4" Carbonaire Carbon Filter

To cool my reflector, I had my fan sitting on the floor outside the tent and pulled the air through ducting from the other side of the tent. So in a nutshell, I used both of the reflector cooling ports on the tent to cool the reflector. If the smell was overwhelming, I would have had the 4" fan pulling the through the carbon filter using the roof exhaust port.

The other common setup that I've seen is to have the fan hanging inside the tent or sitting on top of the roof exhaust and from there ducting runs down into one side of the reflector; the other side of the reflector runs to the carbon filter hanging around the roof area inside the tent.
