I installed a inline 4in fan to exhaust out and installed to 6in flex for fresh air to come in the tent. The tent walls suck in is that ok

@Mr. Grow It how can I tell if it's too much negative pressure? If that is possible

@Jonathan Greene Good question. I don't even know the answer to that haha; I've just heard of people complaining about too much negative pressure. It's not something I've personally run into. Maybe someone else here can chime in.

@Mr. Grow It thanks man.
