Hello m'y room is 100x100x200 cm If I put a 150m3/uur fan as in the photo is this sufficient as an air inlet? I have an adjustable 400m3/ur extractor with carbon filter in the room

If you can create negative pressure then you don't need that fan at all as it will draw air in, you could maybe add a fan to the internal side of that hole to spread round the fresh air inside

Okay thanks mate. My extractor arrives in 2 days. I hope it will allow me to create negative pressure. Open 2 hole for air inlet is better ?

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?

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?

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?

couple quick questions Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?
