growroom vent scenario with pics

Ok, so I attached a pic to explain my frustration, I did alot of research here and maybe I just dont understand, but I want to make sure I have it right before i start setting up this new grow room

Basically From left to right i have:

AC - > TENT -> WALLS

I basically want to pull air from my air conditioned room, into my tent, and out into my foundation, studs, etc.. I dont want to duct outside.. or do i even need to do that.. Can i just duct straight back into the room? since technically the tent is a room of its own, so im technically ducting in and out of the room and, if im just pulling out of the room where to i start from the tent?

Do i just leave a peice of ducting hanging out in the begiining part?

and is it right how im attaching the inline fan to the wall 7" high and letting it suck out of the tent and push into the walls?

Make sure you also have fresh air pulling into the tent. Your plants need fresh air to survive.

Yeah, I see you are venting the lights properly, but what about recycling the air inside the grow area?

My AC is pulling air from outside

How do i bring air in the tent?

Do i have to buy another INline fan?

i'm going through the same thing ralphie. i have the same idea as you for my tent. but i had to post last night about the same thing. you could add house fans if you have holes to take in fresh air at the bottom .from what i'm learning you could add another inline in the bottom just to have that fresh air coming in. are you using a scrubber in your grow ? I plan on not atm.

no scrubber

Maybe ill get an additional inline fan, but just a basic one from home depot to bloe some fresh air in..

Unless anyone has a better idea

In most areas of the world you do not want to vent into the walls because humidity will build up and you will end up with an expensive and potentially unhealthy mold problem.

With two big lights in a tent u need to vent the lights and the tent itself. However, You may not need to vent outside the room if your ac can maintain your room temps, try that first.

And yes, you can probably just have a hole for air inlet but you want two inlets at the bottom of the tent(one for the light and one for the tent) and u need a separate exhaust hole and fan at the top of the tent pushing air into the room.

thanks for the info
