I'm getting ready to build one of the DIY misting systems using PVC and a humidifier for my timor monitor. I have a couple general questions. I know I will have to fine tune it to my specific enclosure, but maybe you can help get me started. Where should the mist be released in to enclosure? Top? Bottom? Middle? How often does it need to be on and for how long? I will be putting it on a timer. enclosure details: 5'x3'x7' with 1' of topsoil/playsand substrate. any input helps. Thanks!
