Slowing a two speed inline fan
Newbiegrower420started grow question 4 years ago
Can I run a fan speed controller with a dual speed inline fan? My 4” two speed fan is slightly too powerful for my grow room. I’d like to slow the fan slightly but I have heard the these types of controllers don’t work with two speed fans? Any advice or what to buy to do the job?

Hi, yes you can.
I have a 4", 2 speed inline fan. I use a variac speed contoller which works on either the high or low setting. Not the cheap plug in one as they just cause an annoying hum. This you have to wire yourself but it's very easy.
Hope this helps

Hello. A dimmer switch is what I use. You know like the one in a dinning room you turn down the lights with. You need to wire it yourself but it works great. Turn it up in the summer and down in the winter. Good Luck. Chuck.

My advice is to find that model on Amazon and go through the questions. I guarantee it's been asked and someone has answered and possibly come up with a work around.
Different fans behave differently, so I can't personally say for sure.

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?

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?

Clip-On FanAt what stage of growth do you guys turn on your clip-on fan in the tent? I've heard that in the seedling stage, they shouldn't be used as it can damage the delicate stems/branches, so how late or how many weeks into veg would you say to wait before starting it up?Week 2

What is the importance of having a fan on 24/7?I have a question about fans, and more specifically how long does the fan need to be on? And is there a difference between having the fan on for 12 hours, 18 hours, or 24/7? I know I might as well leave it on 24/7, but the cheap-ass fan is kinda loud while I watch movies.
