What are you doing with all your exhaust air?

is it leaving the growing area and leaving the room with the grow located in it?

or are you dumping the air inside the room with your grow and then expecting your AC to pick up the slack?

I was doing the second option at first but. Now i solved some issues by exhausting out the room after i got some answers here

Exhaust both tents outside using a Y duct.

I got the y duct but it seems like it really dramaticaly reduces the pull from both tents. Its working but the fan isnt exhausting as much. Basically i have a 6” 440cfm fan connected to the vents. But the Y duct is making it pull extremely weak from both ends.
