Dehum 4x4 tent LED

Okay, humidity in my 4x4 tent rises to 70%, plants are 20 days into bloom, tent is almost full (lost of leaves, transpiration). I removed a lot of leaves, but this is not the option anymore. I've read I must dehum my room where the tent is. But my room is at 30-35% RH, so I guess only reasonable solution is bigger fan and not buying dehumifider? Yes, I vent fan through window. Right now I am running it at 405 m3/h, it can go to 520 m3/h. I guess that's enough per calculations.
Maybe there is some dehumifider that can go inside tent at the bottom under flood table? How you run them, all time? They consume around 400W, which is a lot of heat, if I run already 650W of LEDs inside tent.

get a bigger tent and reduce the watering to minimal is saving the bux

good luck

Your room is pretty dry so turn up your inline fan in the tent to increase airflow from outside the tent, reduce watering, increase temp if it's within acceptable levels. If you don't have an additional fan for air flow/movement inside the tent get one and if you already have a circulation fan, turn it up.

I’m assuming that’s a 4” fan you have?

I have a 6” without a filter venting my 3x3. The tent is always at ambient humidity of the house.

I’d say a 6” would be minimum for a 4x4. But he’ll get a 8” and run it low.
