I only needed a 200cfm inline fan and carbon filter with passive ventilation intake through 4 4” flexible pcv pipes with black filter foam on each end for lightproofing.
Even exhausting out the room into the living room with room temperature passive intake i could keep a 400w mh/ hps or a 315lec in the mid to high 70’s.
This was in a 3x3x6 tent but close enough in square footage to yours for cooling comparison.
Dis i mis something. Why would you need a T and 2 filters or extra fans?
Nope! Not missing anything MIMedGrower. I’m just polling how others would set it up. First time tent grower here.
As you can see in my beautiful drawing, I have only the one set up currently, and feel like it’s fine. I was just wondering: could I use them both? How? And would there be any benefit? Drawback?
Just trying to build my understanding of how this all works more so than I am looking for a “correct” answer.
Still curious about how two fans on a T don’t fight each other. I don’t feel like it would work anyway. It seems that each fan is going to pull from anything before it in the line, and on a T, that would mean the other fan
MIMedGrower, do you run your 200 CFM fan full out 24/7 in the 3x3x6?
I run negative pressure in my tents.
Exhaust fan and carbon filter. No intake fan. Not sure why 2 fans would even be an option.
For sure. I guess to me, if you need an intake fan to help your exhaust fan, you bought the wrong exhaust fan
I always rely on my home temperature as a baseline. Being a modern house, I have heat and ac. So I dont have to worry about my intake temps. Also exhausting in to the house helps with the heating costs in the wintersummer I vent outside.

Sounds good! Thanks for the input. I feel confident leaving my set up how it is, now. One fan, passive intake = golden.
But hypothetically, let’s say I needed a higher CFM exchange rate for whatever reason....
Could this be achieved by putting two fans on a T connector to the same carbon filter? Would that double the CFM exchange rate or would they actually fight against each other?
I realize buying a bigger fan would be the easiest solution. Just curious if there was a solution using the gear I have on hand leftover from a different application.
I get it now. Thanks MIMedGrower! If you have to move the air far, you put another fan down the line.No. The cfm would be the same unless you size up. How far and efficiently you can move the air is what more same fans increase.

Pardon me if I am wrong, but I don't think this is correct. @Jahredi wants to connect through a T joint. That's a parallel connection. Parallel connections add up. If it would be in series it is a different story and I think that your answer would be right in that context.
As an example take a look at (this explanation).
