Tent walls sucking in?

I have the same issue in my 3 X 3 tent, but I have to have my exhaust fan going at 100% due to heat buildup. Even though I use LED fixtures, they still put out a lot of heat....not HID kind of heat, obviously, but the bars are running at about 120 degrees each and that's dimmed down! My overhead fixture is 500 watts, but I dimmed it down so that it's pulling about 375 watts.....and then I have my HLG 300 RS running vertically as side lighting and I have it dimmed down to about 95 watts. I am pumping a lot of light in there and the heat needs to be mitigated.
My tent is also an older one. When I get my next one, it will be a 4 X 4 and I'll run a 6" exhaust fan instead of the 4" fan in my 3 X 3 tent, currently.
I just let the tent suck in for now.

@freewanderer04 That's a cool solution, by the way!
 
Hey, I had the same issue. The fix is to make a simple "support bar." Use PVC or lightrweight aluminum rods – mount them across the walls,, to stop them from sucking in. No need to spend on overpriced add-ons from the manufacturers. I even used old tent poles, works great:cool:.
Just make sure to secure them properly so they don’t fall on your plants;).
 
why not have it on a positive pressure and blow air into the tent to blow it up. have filter on one of the outlets. i drag in cooler air on a 4x4 tent from another room in my basement. no need for 02 as im bringing in fresh cooler air. fan is controlled by a19. walls of tent are puffed out giving more room. my setup works well for me.

It kinda beats the purpose of running a carbon filter were you need negative pressure to properly control smell.

Maybe it would work in a legal state but not anywhere else? It's better to add some framework to stop walls from caving in.
 
You only need a tiny ammount of negative pressure to ensure all air exhausted passes through the filter, blows my mind how many people would rather reinforce their tent than practice proper air exchange, strangling the air flow with a restrictive intake and large exhaust is moronic.

People like intake screens or filters, not moronic.

There's nothing wrong with intake screens or filters, in fact they're essential for most situations, just make sure they're sufficiently sized, otherwise that 8inch exhaust fan might aswell be a 6inch one

I found a very fine meshed "fruit bag" that has cords, I just shoved a 200mm vent hose into the intake hole on both sides and put a mesh bag over it from the outside. It's full of dust after a while, but never inflates so I think it works well and doesn't interfere with airflow.
