Small dehumidifier will work I bought one for inside tent at night for $35 usd. The carbon filter won’t do anything much for humidity, adding another inline fan so one is sucking out hot air and the other is pulling in fresh cool air at the bottom of tent is what you want to achieve, then match fan speeds. Also what size is your tent? Are the fans fast enough to pull out air efficiently, you mention one fan with 171cfpm. So I assume from that you’re space is a small area.
 
To be honest I don’t think humidity for their current stage is bad at all, even at night. I have to lower humidity in my tent down to 50% at night now because plants are beginning flowering stage. But when young I keep rh at 60% to 65% in day and around 55/60% at night.
 
Yes man my tent is 1.2x1.2x2.15..
Have 6inch for a exhaust and half speed in a inline fan same 171cfm.and have 2 6inch fan just for breeze air inside
