U can buy a speed controller for the fan so u can turn it down if it's to much. Also u wana open bottom vents or have some way to let fresh air in. I have a 4x4 tent an s 435 cfm fan an with out the controller it will suck the tent walls in crazy like lol
That's what I was envisioning! I come to find my plants vacuumed packed!.
Will look into speed controller now. I have two screened horizontal vents on the lower end of the tent opened, a fan is blowing air. So far I am able to control humidity and temperature close to where I'd like it to be.
Yesterday, the start of 2 week veg, it was clear air extraction is needed.!
