You'll need the exhaust fan, my friend, your Exhaust serves 3 purposes. 1) to cool the room 2) to lower humidity 3) to get fresh air If you turn the exhaust fan off when the lights are out, the humidity will rise, and the CO2 level will rise. Hopefully, I answered your question and remember " Happy Growing and Free your mind one puff at a time ".

Exhaust is über important, so probably that, however it is good to have airflow over your ladies, and doing so will also help prevent too much humidity and moisture on the plants, which will reduce your chances of any mildew or other unwanted issues.

I would keep the exhaust running, more temperature controle and it creates an airflow on it's own... Fresh air gets pulled in the tent and old warm air gets pushed out... a fan just moves the air around...

Hi!
What is your humidity during night?
If you have no troubles at night time humidity then you can choose which ever you want but keeping the exhaust on all the time is better IMO

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?

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.

How to reduce humidity in my grow space?I'm just an amateur and am growing in my closet as I have very limited space. It's a small space in which I can't cut holes or openings. I use a small fan and a air purifier. Should I get more fans? Does a carbon filter or inline duct help if it can't exit out of the closet?

High RH in flowerI find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solution

Help with airflow. I've got an extractor and 3 circulating fans. Would a powerful inline fan be better than the 3 circulating fansQuestion about environment here.
I've got a 5x5 tent. Total 46m area.
460m3/hr needed to be extracted.
Extractor fan is capable of taking 600m3/hr.
I did have in an inline fan but it's no longer working. Do I need another inline fan ?? I've opened two ports for passive intakeSetup. Ventilation
