So, the title is pretty straightfoward. I was thinkin about getting some 127mm extraction tubes and make it really tight to fit the filter. TIA

Yeah should not be a problem, you can just use a Pipe Fan Connection Reducer 100 mm / 125 mm between the exhaust and filter

Humidity problems
Can 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?

High humidity in the morning
I’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)

Connecting intake fan to my tent's mesh for most efficient ventilation
So as a couple people suggested, I bought an intake fan, and am using it to bring air in from a different section of my closet. How can I stick the ducting to my tent's mesh? Is tape fine? Any other ventilation tips?😉😀

Cooling whilst using humidifier outside a small grow tent
I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?

Dehumidification
When the outdoor air dehumidification fan runs it produces a periotic negative pressure in the grow room. What is preferred: a negative or positive pressure in a grow room for this method of dehumidification?
