I actually got the inkbird controller for humidity myself and actually have the temperature controller and datalogger on the way in the mail! :)
I'm running a Co2 bag, so im trying to conseal the enviroment as much as possible.
-And when i plug exhaust fan to inkbird, it exchanges too much air.
my solution for now, instead i've plugged up cooling fan to blow unhumid and cool air in.
I am growing with LED from Lumatek
Been keeping the room cool (20degrees) it helps a bit, but it is a bit cold for me ;)
