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

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?
Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

2x2 Circulating Fan
What is the best circulating fan for a 2x2 tent available on the european market? I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

Maintaining VPD
I've got my photoperiod doing well in a 2x2 tent. I'm trying to regulate my VPD with what I have on hand. Currently I'm running my exhaust fan for 8 minutes every hour to get an average VPD around 1, but I'm concerned about the swings. Am I micromanaging?

Smell through filter exhaust
The smell inside is quite strong and is coming through the filtered exhaust. Is this normal, or does it mean I need to replace my filter soon?

How crucial is an exhaust fan and a carbon filter?
I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

How do you deal with the humidifier in hydro ?
So I bought a dehumidifier as advised but now the room gets hotter (Had to setup an extractor to pull the hot air and now I have no intraction) and during the day EC goes up of 0.1 or even 0.2 (from 1.8 to 1.9 or 2). I suppose there are more nutriments because of dehumidification

extractor fans
I'm after a new duct fan. Needs to push at least 400m3 per hour. And the main criteria is noise. Below 21dba would be the dream.. curious to what folks use and if I see one that meets my criteria I will buy it.

How do I know my filter is still running ok? can it wear off in just a month?
I have a vulcan carbon filter for a tiny tent. It runs 24hrs a day for the last month. Now, the smell coming out of it is not neutral anymore (not strong cannabis), but it is a bit heavy and I'm getting paranoid. How do I know my filter still runs fine? High umidity is a factor?
