some of the foggers ive been looking at have a built in fan humidety & moisture control so in theory you could run this system outside of the root camber and nute tank
(this is my preferance as my current project uses a ozone generator to steralize the rooting camber)
yor idea is definitely on the nose with a little bit of reaserch it should work well
ill gather some of the info on foggers an e-mail you if you want it.
