Good morning, we bought a 4" inline exhaust fan, however there is not a timer on it.
Does it run all the time to keep the 1-3 minute circulation? Or do we need to find some kind of heat controlled timer? Reading your book and watching your videos but we are still confused.
Help please.

I have 2 tents and my fans stay
on all the time and it seems to work good for me. Here's some photos of my current grows.
4x4 tent growing papaya stomper photo period with 6" exhaust fan on 24/7.
