How to control VPD while lights are off?

@Skydiver I’ve since then purchased me a 6"infinity inline fan. Its been a game changer for sure. One of the best investments so far.
I’ve also recently read that vpd doesn’t really matter when the lights are off,so that’s a plus.
Thanks for the suggestions none the less. Greatly appreciated.

@Lost4Sure I use the same one. Infinity fan has been one of my best purchases. I was using an old 6" vortex inline with the manual dimmer. Boy was hard to stay on top of vpd with. Haha

Are you using the combo version?



I have my intake fan set and my heater and dehumid/humidifier on and it keeps my temps and Rh within a couple points either way. Hope this helps any friend.Sorry just realized I was late to the party. Lol
