Building my first snake rack and have a question regarding flexwatt. I plan on doing 6 levels (mixed 3 adult 3 hatchling) I plan to use four strips going down the back, would this be good? I know that each strip will hit a hatchling tub but is it ok for each adult tub to get heat from all of these strips? Is it possible to use one thermostat to control all 4 strips or will each strip require a thermostat? I have one now It is a Zilla 1000 watt model.

Also can the flexwatt be "pinched" by the melamine shelves or does it need some space. Lastly is ventilation needed for this or does heat not need the space to escape?

Sorry if these are dumb questions just want to get everything right
