You don't need a fan to circulate the fog.

You do have to watch how much air you pump in if your using an airstone as that displaces the fog.
Jollyrancher Reviewed by Jollyrancher on . Fogger Design Ideas? It's been a long night but after some serious soul searching I think I want to try a fogger system. From what I can tell I bought the good fogging unit which is the aeromist 3 head teflon one. Also from what I can tell I will need to incorporate a fan and some sort of return system for the fog. I wonder if I could just use a single tall tote then mount a pc fan inside to circulate the fog? I could suspend the fan from the lid far enough below the roots yet above the fogger unit.
