I am facing a temperature problem again....My tent reaches 84.2F, which is too hot in my opinion. But my humidity is perfect. On the other hand, if I activate the ventilation, the temperature of the tent reaches 76F, which is perfect, but the humidity level drops dramatically to 35%.

Ventilation questionIs it possible for me to take down the walls of my tent and leave the frame with the lights on it to let the plants get more space? I don’t have a way to ventilate the entire closet from an external source, just been ventilating the tent w/ an exhaust fan and carbon filterWeek 5

Dehumidifier recommendationsAny recommendations about a dehumidifier for the 4x4 grow tent? I think even with vacuuming run-off more frequently, I won't be able to get humidity consistently down below 60%. Amazon has some in the 45-90 USD range...Other. General questions

Now getting condesation in my tent when I've added this duct to a pipe exiting the house? Am near harvest too.Didn't have an issue with condensation inside the tent before, now that I've attached the duct to a pipe going out i'm getting condensation inside... Does the set up look right? I've hooked up to a smaller tent too via a T. Could it be pressure?Setup. Ventilation

Humidity problemsCan I have some advices on how to lower my humidity? I’m having some troubles lowering it since my plant is now flowering. Usually I can’t lower it from 60% while my temps are always on 27/28 C during lights on.
I will leave a pic of my setup here. Should I change something?Setup. Ventilation

I made a firebomb?Is it a fire hazard if 5v computer fan is jammed and the power is on for 2-3 weeks?
I'm far away from home and I have camera in my growbox. A tape has fallen to the fan and it is not rotating. Can it heat up so much that fire starts? Should I drive 1600km for that?Setup. Ventilation
