It depends on the space you can dedicate to it and the frequency at which you can / want to take care of it and empty the tank. Some models can be connected to an external tank or directly to a drain. It's the best options. Otherwise you have to get a model that can work for a whole day without needing to be emptied. Small models / portable can do in some restricted space in countries where the ambient humidity is lower.

Maintaining VPDI'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?

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?

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 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?

Is the high temperature something to be concerned about?

Grow Tent/Room setup in the basement - dehumidifier or humidifier needed?I’m planning a small grow setup in my basement and have a room that’s holding a steady 17–18 °C (62–64 °F) with about 55–58% relative humidity. My plan is to vent the exhaust from the grow box straight outside through an existing duct. Will I need a de- or humidifier?
Thanks!Setup. Ventilation

Humidity problemsCan I have some advices on how to lower my humidity? I’m having some troubles lowering it since my plant is now flowering. Usually I can’t lower it from 60% while my temps are always on 27/28 C during lights on.
I will leave a pic of my setup here. Should I change something?

Best way to cool your tent/ growbox?So I’ve built a custom growbox using an IKEA wardrobe, air vent for intake, two circulating fans, carbon extractor exhaust, and a 600W LED grow light. Temps average at 29 degree Celsius with the lights on full, is this too high? Best way to bring the temps down? Many thanks!
