Which 6” fan would you use for an LED flower tent? My standby HF ventilator isn’t available to me :(

Hi all, I am looking at a new LED only flower setup, and need to source a 6” exhaust fan for it. I need a minimum 400cfm. The last tent I set up, noise was not a huge issue and I used an 8” ventilator from Harbor Freight - but that isn’t available to me here in Canada, and I’d like something more purpose built.

Heat isn’t as much of an issue as air exchange for humidity and odor control.

I have available to me Can-Fan, AC Infinity, iPower, or Vortex fans. I can also find a Panasonic.

Airflow is a priority with noise a close second, what would you guys recommend? If this were 6 months ago I’d go to the hydro store and see if I could look and listen to them all, but everything is pickup only now.

ipower is the loudest then the rest are probably similar. You can ask the decibel rating and compare to the cfm.
