Exhaust fan

[chronicville]

How often should i run my exhaust fan in a 4x4 tent. Should i run it 24-7 on a low speed or just to keep temp down when the light is on?

I have a clip on fan too should that run on low. 24-7 ?

Most use a speed controller to reduce speed if temps go down.
You need to control temps and supply CO2 with fresh air.

24/7 and it should be exchanging air 3x per minute. Its not just for temps its so the plants can breathe.

i seen a titan control for your fan

what it does is day and night. and also it has a day and night low temp for your fan. and also it has just run regular. it has photocell. its like $80 its on my wish list of automation

there are many and different brands. grozone makes some too i seen

u can seach amazon for:


Titan Controls 702755

Titan Controls 702760

Titan Controls Spartan Series Fan Speed Controller


dont forget to check the amp draw on fan and make sure controller is rated for that draw


when using this keep in mind it wont consider co2 levels like cultivator said, humidity levels or anything else so those should be controlled also
