I call it Smokey.
I have the mist facing the hot end where it's the driest, but do you think this will negatively affect the lights? I could always aim it somewhere else or take the head off and let the mist rise up slowly.
About 10 minutes after I put it in, the humidity went from 60% to 75% on the medium setting, which is high for daytime humidity in my set-up. It's never been that high with the lights on. I probably won't need it at night since the humidity always raises to around 80%.
