Are you just trying to bring temps down in the tent while maintaining neg pressure in the tent? Where do you have your exhaust blowing out and your inlet coming in within the tent?

and yes im trying to bring temps down to steady 75, if i close the tent it jumps to 80 with the neg pressure, so im close just not quite there.

Im pretty much in ur situation.....i got little mesh vents at the bottom i open 1 and the neg pressure goes away....i came to the conclusion im just gonna vent a portable ac into that badboy

ive been wondering this, can you elaborate on what you mean by putting the filter on the passive intake?

You said you were keeping a neg pressure to help "Keep the smell at bay during flower". Use a larger passive inlet to reduce the neg pressure & cool your tent better when it is closed up. If your exhaust fan runs constant, there should be no worries of smell during flower when the tent is closed. If you have your exhaust fan hooked to a thermostat controlled outlet and it kicks on/off as needed then put a carbon filter on the inlet for when the fan is off. The inlet would be the only place smell will be able to escape the tent when the fan is off -which is remedied by the carbon inlet filter.

The basic idea is to use something that will block air from moving through the intake when the exhaust is off without restricting air flow when the exhaust is on. There are pieces of equipment that are purpose built for this that won't be as restrictive when the fan is running. They're cheaper than filters too. With the springs when the fan shuts off the flange closes and when the fan comes on it opens. You can them without springs that just use gravity to close them that are a bit cheaper and even less restrictive.They're about 20 dollars here.

It doesn't sound like you're having an issue with the tent getting too cold though. You'd only need to block the air flow if you had to shut off the fan because your temps are getting to low but that's the opposite of what's happening.

Yes you would just disconect the ducting at the light
And tuck the ducting up by the filter till needed


Edit to add just noticed i wrote fiter on the FILTER lol
It was late when i wrote that ha ha

Do like joe and

Okay the two bottom openings are intakes. Is the inline fan on the outside sucking air out opposed to pushing it through the tube?

Whichever you prefer .
Can be inside the tent or out whichever is easier

I put it like that because its more efficient to pull than push.

Plus with the 2 intakes youll have good flow while maintaining a neg air pressure.

With the dampers you dont have worry about smell crawling out as much
