My exhaust is a 6inch Infinity. Love it. I set it to 7-8 on the basic ass fan controller it comes with and I leave it. I always set and forget my exhaust fans. Then you have a constant.
I open a single panel on the tent to allow air from my house that is 68f to enter the tent at all times.
I then use a 4inch Infinity Fan with the Controller 67. That controller will pull in supercooled air from outside as needed. Since I have the panel open when the fan is off it isn't pulling from the 4inch ducting, maybe a little.
I blow the cold air into a box fan. That box fan blows underneath my canopy and spreads the cold air which rises to the top evenly. I only use a single box fan underneath and I don't agitate the top of my canopy with more fans as it just makes things hotter blowing air at the bulbs and spreading it around.
With this setup I can really cool the shit out of the plants in the last few weeks of growth and it makes a HUGE difference.
I grow so much during the cold months I don't need to bother indoor or outdoor in the summer.
Best part is, if you buy the cheaper controller/fan combo then buy this controller you'll end up spending not much more than the regular controller combo. It's a smart Bluetooth controller with an app btw.
