Help me out with exhaust, intake and room temp sharing. *PIC*

Here is the room, I am trying to circulate the air from the AC room on the right, to the room on the left, so both rooms can be cool.

Plz can somone help me out by telling me where i should put a vent for air suction from the AC room to the NON ac room. And how i should do it...

Should the air inlets on both rooms be fans sucking IN or out? Or 1 blowing in.. and one blowing out to keep circulation?

Your fan for your lights might be a bit overkil. I would use a 6" 240CFM fan for the lights, then use a fan rated to clear the air in your room 5 times per minute and scrub the exhaust air with a carbon filter. Use a passive intake, or use an active intake. The whole point would be to keep the air at a slight vacuum inside your room.

Your design is okay, but your doing too much air for your lights. Really, in all honesty you don't need that much air for the fans if your going to cool them like that. That will take care of most of your heat problems for the room.

Like I said, heres your list:

6" 240CFM Fan for lights
1-2) 4" 170CFM for air movement.

Use a fan controller for both to control speed if stealth is an issue, otherwise run them full blast. I wish I had that much room to work with!

You know i missed that part about the AC.

The goal is to circulate the air, so why not run a fan into the un a/c'd room and another one out to remove the heat.

Put the intake at the bottom and the outlet at the top. Should do the trick again with dual 170 CFM 4" fans.

if it was me...i would flower in the room with the a/c unit and veg in the other...use an soler palau 4" inline fan placed at ac vent level mounted on the veg chamber side. cut a 4 1/4" round hole in the seperation wall as close to the a/c vent as possible. run the ducting to the fan so it pulls from the flower into veg...plug the fan into a thermostat on the veg chamber side at desired temps....keep the ac temp at your desired level in the flower room...when the fan kicks on in the veg side it will pull air from the flower side if the flower which i would keep about 5 or so degrees cooler than the veg side...if the flower room gets to hot the a/c will kick on...the fan in the veg room will kick off when you are at desired temp and let the ac cool the flower room still.....also...if im looking at the drawings right it looks like you are using some type of enlosed light cooling setup ....if so how are you exauhsting the stale air from the room....

hey guys thanks for the info!!

Ok, so i should make a hole inbetween the wall that seperates closest to the AC, and put a fan or to duct the cold air in.


What about the Air vents? how should i position them? Each room as a hole on the bottom of the room next to the door.

i use black abs 90 angles for my cab vents...the black material with the 90 bend helps against light leaks...
