Indoor high humidity. good air flow?

[realer_dn_most]

hi guys.

quick question..

i currently have 3 AFs on 20/4 cycle and only 4 weeks left til harvest in a 120x60x150 tent with a 4" exhaust fan and the intake flap removed for passive intake. i also have a 9" clip on fan blowing air over the canopy of the plants (not osc). i also have a small 1.5l dehumi at the passive intake but not sure if its helping.

my humidity when lights on is always around 45-55% but lights off it sometimes gets as high as 75%

ive heard that with good air flow. high humidity isnt always a problem.

any ideas what i can do??

There are a lot of auto growers who use 24-0 lights and would disagree.

I run 24/7... no issues... I do back down to 18/6 over summer, but that's to keep heat down from 12-6 pm.
