You know I have been all for this.
However I just seen this, and they bring up some interesting points.

So now, I am not really sure where I stand lol.
However, would a heat humidifier solve the issues, they mention?
I mean I guess it wouldn't. Idk.
Maybe, if we used a separate fogger (we do, or I do, OP does) and use a UV disinfectant light to disinfectant the water supply? Idk, has to be a way to have our fog, and disinfect it too (haha)
So, even the article states prolonged WET conditions. That would potentially cause health issues faster which is why I have always suggested allowing the enclosure to dry out between mistings and before lights out. I am using the fogger for a few hours overnight as of now and I don't notice any water build-up, just higher humidity (the desired effect for this scenario). I have not noticed any real drop in temps overnight yet until the first misting of the day which occurs about an hour after lights come on.
Definitely a no-go in my opinion on warm mist. That would definitely be more conducive to bacteria growth.
