Depending on the size of the enclosure will depend on the mist nozzle coverage. I have one pump for a dart frog viv and uses three nozzles, it is a 36x24x24. I also have one pump for two Chameleon set ups for my wife which are 4' X 4" x 3" with 4 nozzles each but does not require such high humidity.
I would say Mistking is the way to go. A little expensive but worth the money. https://www.joshsfrogs.com/mistking-starter-misting-system.html
