Negative Pressure Issue

Hello everyone, I am seeking some advice.

I have a 5x5 grow tent I made myself using poly and a wooden frame. It looks fucking beautiful, I'm pretty proud of myself.

Here is the issue. I installed a 6in exhaust fan that spits out roughly 435 cfms. My 6in intake is through my window, with a bug screen over the duct. When I turned the fan on, the tent nearly collapsed itself because of the negative pressure. If I install a carbon filter, will it lessen the pressure? Or will I need another intake? Thanks.

just add some more passive vents, and a carbon filter wouldn't hurt.

A carbon filter will definitely make a difference, so I'd try that first if you were already planning on using one. If not, add another vent or put some kinks in the exhaust ducting.

yeah i have a 170cfm IF coming. that fan is a horse man, it would probably work for Tony Montana's grow op
