Excited newbie here! 4x4 indoor

This is the fan on top of the filter outside the tent yes? What’s the gauge? Fan controller? Sorry again I’m a visual learner lol

Indoor Grow 2x2

I have a 3x3 and a 2x2. You can exhaust a 2x2, but you need a 4 inch system, not 6. My 6 inch fan inflates my 3x3 on the lowest setting. [20220208_185457] This is my exhaust/filter, outside the tent. I don’t think there’s another way, I tried a few things.
