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?

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 FanWhat 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?

Speed of outgoing TD SilentDo you adjust the ventilator speed over time? I have a TD Silent with 5 possible speeds and keep the lowest speed at night (so I can sleep) and on 3 or 4 during day to be sure. Is there a trick to find the best yet lowest speed?Setup. Ventilation

Using humidistat to control fan, will this cause problems? So far fan running for 30 secs every two minutes! Plz advise if this is not a good idea??My exhaust fan is to powerful no speed control just two settings. On the lowest setting the fan is still sucking all the humidity that my humidifier creates out of the tent. So I have bought a humidity controller hooked it up with the humidifier and fan.. It’s working great!!Setup. Ventilation

Cooling whilst using humidifier outside a small grow tentI have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?Setup. Ventilation

Grow tent TemperatureI have a 90cmx90cmx60cm grow tent with a VIPARSPECTRA 300W LED Grow Light inside.. How much will an extraction fan and carbon filter bring down the temp inside? In this heatwave my tent is running at 33 deg C, no plants seeded yet. Will the fan be enough or should I get a cooler?Setup. Ventilation

Firstly is this an issue? I normally have a reading of 50-60% but I can't lower it today. Second, how can I lower it.Week 8

Do you think this is a better position for carbon filter so it can have better airflow or is it more important to scrub air from the top and have 2 90 degree bends?
I'll probably try this in my next grow.
Pic with drying plants is setup from before with 2 90 degree bends.
