Fan controllers

so my 6 inch Can-fan was pulling way too much air out, so I put it on a blueprint fan controller. So can-fan tells you not to operate at 40% or below as you can burn up the motor. I hooked up a kill a watt meter to find out where 40% lies. Well at full speed it runs at 75 watts so 40% would be around 30 watts...low and behold the lowest the blueprint controller allows it to go is around 46 watts. Which is fine for me as I will not be running it that low.

Now I probably will get a day/night fan temp controller so I can just "set it and forget it" ...just a bit of info on my set up. A simple Kill-A-Watt meter is like 20-30 bucks and is nice to be reassured.

Beware if the fan is on a carbon filter, low volume will give poor scrubbing performance.

The molecules need to “shear” as they flow thru the carbon. Your filter should have the min. amount of air flow listed as well as the max.

I rely on the "fart" test. Drizzle stands outside the grow room by the exhaust while I let em rip inside. We can tune that speed in good with this method.
