Hi, This is my first time growing and I am using a TopoLite tent. It has an 8 x 16 ventilation port. Do most people open these? Right now I am drawing through 2 hydrofarm bug shields a 4" and a 6:. Right now the tent sides are getting sucked in. If I slow the exhaust fan the temperature goes higher than I would like. I have thought about opening the flap on the outside of the tent and maybe duct taping a filter over the outside of the square port. Maybe I am going overboard and I don't need to worry that much about dust. This picture is when I was setting the tent up, before the light arrived.
