l'estrazione va in alto dove va l'aria calda
in basso meglio mettere una ventola in ingresso
per quanto riguarda il box gonfio ,come hanno scritto non va bene perche intanto se hai problemi di odore si sentirebbe molto di piu
in piu si formano delle sacche di aria ferma e la circolazione non è ottimale
comunque nel foro in basso dovresti mettere una ventola con portata minore dell'uscita

CalyxHunteranswered grow question 2 years ago
I personally use carbon filters for both my intake and exhaust. I use slightly more intake pressure so the tent is poofed out just a bit. When you press on an outer side wall of the tent it should slightly spring back out. This positive pressure will prevent pests and dust from getting sucked in through seems and openings. I filter the exhaust to prevent my home from smelling like cannabis flowers. I have a 6" inline fan and carbon filter for intake and a 4" inline fan and carbon filter for exhaust. Both inline fans have potentiometers and the ability for speed control so I can dial in the positive pressure.

You can use a small Inline-Fan with half the m3 of the exhaust fan in one lower hole. Hope this helps

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.

Do any body have any experience in making your own carbon filter?Thinking about making one from two steel mesh "ovals" with +-2cm in between. Use some filtration cloth so the carbon don't go through the mesh. And will fill the space between the meshes with activated carbon used for this purpose. Do you think its going to work? ThanksSetup.
