Well, they make misters for misting people outdoors. The technology exsts, you just need to adapt it. I bet if you set something up in a medium sized aquarium tank you could have a little rain forest for your clones.

You know they gotta have the kind of stuff you would need for terrarium geeks.

Otherwise, damn, sounds like you got the other stuff fine tuned. But if you're taking pure H2O from the air and putting that into your reservoir, how do you keep the ppm's up in your reservoir? Or do you just let them lag for sake of a holiday?
