Exhaust always necessary, intake for a small amount of plants is enough just opening the door daily...

If door open than Intake. Becouse the breeze will move plants and they will become stronger. Thicker main steam

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?

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%. 1- Keep Humidity or 2-Keep Temp

it's getting too hot. I added 2 fans inside. Do you think I can enable them 100% of the time/all day? Or is it bad for my plants?

Exhausting air outside when using Air Conditioning, yes or no?
Hi there. This is my first indoor grow in soil. I have a room with A/C. The grow tent is in that room. My question is, should I be exhausting the air from the tent outside or into the room. If i exahust the air outside, isn't it counter productive to the A/C?

Temperature Probe. Where to place it?
I use a Vivosun exhaust and control hub. It comes with the temperature and humidity probe. I am curious, based on experienced growers here, where do I place this probe? On the floor or do I let it hang mid-way in the the plant itself?

Peltier dehumidifier @300ml per day adequate for 3x3x6 tent? Alternatively, a conventional dehumidifier outside the tent?
Peltier thermoelectric dehumidifiers extract 300ml of water per day. Weak compared to compresser units, small and use less energy. Is it enough? Would a conventional dehumidifier set outside of the tent near the intake be effective, or does it need to be inside the tent to work

Risk of bud rot with these conditions?
My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!
