Tent walls sucking in?

Just thought I’d share my solution after seeing how these companies are charging for something that should be included.

I use pool noddles on 3 walls. $2.99 at walmart.

Adjust your output exhaust fan lower and the inlet higher to compensate.

Yes, too much negative pressure.
Either lower the exhaust fan speed or open up the intake holes more.
Can't see if you have any intakes open on the bottom of the tent?

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!

I'd be worried about bending the bars doing this. Knowing myself I'd probably over crank it and ruin my tent lol

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.
Just make sure to secure them properly so they don’t fall on your plants.
