Can't increase RH%

My room specs
Sealed Room 8x18x7
Have a small 3x3 mother tent and the rest is a 4x12 flower trays all in the same room
bottled co2 with fuzy controler, dehumidifier and humidifier, split air con, led lights/ led drivers / fans and so on.
room stays a constant 84 degrees

I am running my humidifier during lights on and can't raise the RH above 40% when i go in the room you can see a haze from the water vapour in the air.

The room i know the room is airtight because it holds co2

Are you sure you trust your hygrometer?

i have 4 separate hygrometers, 2 calibres 1 is brand new

I would collect the water from the AC condensate drain and quantify how much it's pulling from the air. Is the humidifier able to boost the RH% when the AC is off?

Unless you have the dehumidifier running at the same time then only thing that would fight the humidifier is the AC unit.

Only other thing is the humidifier is too small to outdo the AC unit. If it can boost above 40% when the AC is off then you know thats the answer. Evaporative coolers are the best humidifiers.

If you see water vapor in the air and the RH% is saying 40 then somethings not right... either the hygrometer or you lol.

Its a 1 ton AC split system and allot of water does constantly run from the condensate drain

and how is that LED or other lighting related?

I can tell you once your girls to get some size on them, they'll transpire a ton and humidity will be an issue to get rid of. Lol.
