For my adult enclosure I will definitly go with aluminum screen all the way around, however for the juvenille enclosure which I am finishing tomorrow Ill be using the vynal mesh. I went into a LRS today to check out some stuff, I need to get a fixture for a reptisun UVB bulb...it looks like the bulbs will not fit in any of our fixtures. They did not have any auto misters. I dont think a nozzle from mistking is the only thing that will work. There are plenty of good high pressure nozzels at Home Depot used to set up strong outdoor mist systems, curious if these will work...I need to look into it more, my biggest thing is finding a sufficient pump that will power the mist system. Let me know what you end up using. Post some pictures of you set up when your done if possible, Id like to check it out.
