I plan to cut my current room in half and run a flip flop set-up...hopefully running half the lights at one time can save me from using my kW hungry window AC. I have 4 x 600's with adjust-a-wing reflectors (not air-cooled) and a 12" Vortex exhaust (I think 1140cfm) plus a big-ass carbon filter, similar cfm's. My room is 13' x 6', and I plan to divide it with a wall so that each room is roughly 6' x 6' and will have 2 x 600's. My idea is place that filter along the top of the dividing wall, and build a light trap type box around it...so it will be right in the middle of the 2 rooms...and then each room would have it's own passive intake. Would this work or should I just get another fan/filter?

I've tried this before, splitting my carbon filter for two rooms, I found it very hard to keep it light sealed. To avoid that potential hazard/disaster I would just run 2 carbon filters and fans. You might be able to vent from room A to room B and vice versa if your night time temps need to be raised a little. It can be hard balancing the temps in 2 side by side rooms, depending on where ballasts, intake fans, and the A/C is located, it def requires some dialing in.

Thanks bro...I've had enough problems with light leaks so I'll go with a 2nd filter/exhaust then.

if you dont have CO2 and the rooms are next to each other this should work.

air intake in room 1, air exhausts to room 2, room to exhausts through filter out of room. the negative pressure in room one will prevent any smell from leaking out anywhere but into room 2 where the filter is. at least this makes sense in my mind....
