Hi all currently struggling with high rh when lights go off. Is a dehumidifier the only option? I have an active intake fan that brings air in, 2 oscillating fans and a rvk exhaust fan, all of which are left on 24hrs. During the day temps are 25/28°c 45-50 rh, as soon. As lights go out my temps drop to 22°c my rh has been sky rocketing up to 65%. Is there any tips to lower? Preferably avoiding a dehumidifier as tent is in bedroom and noise is all ready quite substantial

I use exhaust to flush tent of humidity 1 hr before lights out to 1 hr after. Intake will happen if running exhause in tent. Change it around. Best advice l can give with info. Was doing this when ran closed tent.

Your cheapest and easiest solution would be to try and increase the temp during lights off to what the temps are during lights on. The increase in lights off temp should lover your RH. So throw a heater in there, will make a difference.

What is the source of your incoming air? Is it coming from inside or outside your home? If its coming from outside you could always pull air from inside the house instead, that will also lower you humidity.

Your intake air is going to be the same humid air eh? You can humidify a tent but must dehumidify the room your tent is in at a minimum. Buy the largest unit you can. Use the water on your plants.

Problem is the tent is in the bedroom and can't really have anymore noise then what there currently is. I could try in taking from another room that has windows closed

Or you could try not running your intake when lights are off.

might help to lower RH as youre not forcing air into the tent instead you’re negatively pulling air in slower than the intake fan.

Do you defoliate at all?? Lowered mine by about 10% RH by doing so.
