4x2 setup with pics help!!

Hello all,

I have a 4x2 tent inside a closet with a 400w hps.
I am trying to figure out which one of these 3 drawings would be the best for lowest temps.
Remember its only drawing in air from my closet and drawing out air into my closet.

You need cool air coming in, not air that's already been heated. But drawing 3 would be your best bet imo.

I know I should have cool air coming in but I cant. Thanks for your opinion, does everyone else agree?

I have a tent in my closet....I run filter ducted to light ducted to fan pulling air through and pushing into attic. You can get away with one fan and a passive intake. Temps will be hard to control unless the closet is open and some cooler fresh air can be pulled in. I actually went away from HID and got a LED to replace the 400....temps are much cooler.

Also, you might want to put the filter before the fan. You want your fan to pull air, rather than push it. If that makes sense.
