Leave you fan on?

Hey quick question do you guys turn your os fans off in dark time and why
also would it raise the rh?

I have a cooling fan 18/6 for my HPS, the closet is open 24/7 so lights off there is a little airflow when the stink begins I will run a seperate fan/filter 24/7, best to have fans run 24/7

I turn my light cooling fan off at night but keep the osilating fan on 24/7

Yeah that what I do but I never questioned it I want more rh in the veg room but don't know if this going to work happy oz day champ drink a beer for our country

when my girls light up in the morning I noticed that the RH has risen 7-10% through the night with NO airflow, get a humidifier I have a dehumidifier 30.00.. gl
