This will work right? 4x4x8 tent vent question...

I am new to the tent game.
Things are going great but I'm betting the little lady is going to want me to upgrade to a filter system soon.

Currently have 3- 220cfm booster fans running.
1 on HPS and 2 venting tent.

Even with a 315w cmh in a wing it stays nice and cool.

Here's my thought on a filter system. Keep in mind it doesnt have to be 100% smell proof.

Looking at a 8" 720cfm system with filter. And getting an air cooled hood for the CMH too.

1- 220cfm booster fan on each dedicated inlet for the lights.
They are 6".

So 2- 6" exhausts running out of tent to a 6x6x8 wye, connected to a 8x8x8 wye with an 8" exhaust coming out from tent for its exhaust.
Then 720cfm fan to finally the filter.

Anyone see an issue with this?
 
Nevermind.
Think I'll try running intake->booster->hps->cmh->6x6x6 wye inside tent with fan and filter outside...

That would leave me with 2 extra 220cfm boosters to use for intakes where needed so I think I'll be good with the 6" 440 cfm system.

Edit...bleh no. That wont give negative pressure so the 8" it is!

Hard to follow your logic.

Correct way to do it if its one tent and two lights.

Filter>fan>light>light>out

or

Filter >light>light>fan>out.

Not seeing why you need any duct boosters.

So a 720cfm fan and three 220cfm is what you’ll be running? Seems like a ton of air for a 4x4. I agree with above just put fan on filter and set it on the floor it’ll take care of most of the smell

I think you will be pleasantly surprised with the cmh and temps. I doubt you will need to air cool the hood. I have had 3-315cmh(Hortilux bulb hung vertically) in a 4x8 with a 10" mountain air on a 8" 745cfm fan on a variac. There is a 4" inline for intake on a variac to keep pressure. The temps do not exceed my room temperature by more than 1 degree.
