I ran a similiar fogger system as you describe.
If you use a fan to circulate the fog without a return system, the fog must go somewhere. It will creep upwards through your medium and your stems can become too wet, soggy, fungus, weak. etc.
Also, the ultrasonic foggers increase even large res temperature way too high! You will need a chiller to continue this system. Seems to work with clones without a chiller, as they like warmer roots, though
stagecoachcobs Reviewed by stagecoachcobs 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.
