answered grow question 4 years ago
Just had a quick look and that looks fine to me, I like to put the fan on a timer to give it a little break a few times a day. Unless it’s too hot with lights on, then I will have it off for a couple of hours while they sleep.

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?

ventilation for a 4x8 ? basically is that too much negative pressure and if so should I get anther intake ?
currently using a 200mm inline exhaust fan that has 914 m3/h(537,9 cfm) max currently using it at its medium setting of 792 m3/h(466,15 cfm) and using a 125 mm inline intake fan with only 330 m3/h (194,23 cfm). Should I get anther intake fan or should I put the exhaust to low 680

Carbon filter sleeve needed?
I use the carbon filter on the exhaust side. On the intake side, I have a dust screen mesh. The tent is quite clean so that’s why I don’t see the need of the pre filter. Would also probably load the inline fan a bit too. What’s you thought?

Currently using a 4x8 tent in a garage that is dusty. would getting a extra intake be better for my plants?
Currently using a 200mm inline exhaust with a max cfm of 537,96 and using a intake with a max cfm of 194. currently using the exhaust on medium setting so 466 cfm. would it be better for my plants to get more air from outside with a new but small intake of about 128 cfm ?

Optimizing Airflow and Humidity in Grow Tent: Balancing Intake and Exhaust Fans
Intake fan: 180m³/h, exhaust: 340m³/h. Tent appears sucked in—is this problematic? Is equal airflow crucial? Struggling with seedling humidity; excessively dry (50-55%) when the humidifier is off. Need advice on balancing air circulation for optimal conditions.

Venting multiple tents
Opinion for venting multiple tents to outside. Vent all tents directly to outside or vent into grow room containing the tents then vent grow room to outside? Cold dry winters and hot humid summers where I live.

How do I drop my RH down when nothing works? Check Diary. Will defoliation be a good idea? Open tent door and leave it open?
My 2x2 is starting to crowd. This is driving the RH to over 70%. Should I defoliate to help with crowding and RH? Or should I just leave it alone? RH in lung room is 48% Exhaust fan, high or low with a dehumidifier, doesn't work. What should I do? Defoliate? Thanks! Check diary.

Inline fan and new air
I mounted my 4’ inline fan with carbon filter in my tent as high as possible, with the duct coming out on one side.Is it correct that it only sucks air out from the tent? Because I’ve read that it should also bring new air in. Should I make the air from the duct blow in again?

Best extractor or vent for grow room 60x60x160 indoor reduced space.
Which extractor or vent should I use for a grow room of 60x60x160 . I need something that gives good airflow in a reduced workplace. I don’t have a window near by so I need something good. Not too much expensive of course. I was thinking to buy a carbon filter too.
