Hi Jimm
My outtake fan is the only thing i leave on for 24 hours. (mainly due to convenience that my relay timer only has 3 plugs Light, Movement Fan and Tube Heater)
That's always worked well for me. I guess you have more plants and a bigger space, so perhaps come flowering you should check the lights off humdity (after a couple of hours) - If it's really high 70+ I'd get a movement fan on 24 hours aswell to keep airflow good and help keep the bud rot away!
Hi Blue,
I've never seen my humidity over 30/40? I wondered because I thought maybe they would need the rest after
the 20hrs of light and the fan is quite big (12") I usually just put the fan down to number 1 rather than 2
when the lights are on.
:thank:
