I'll try answering your question based on my personal experience raising several Retics from hatchlings to monster size!LOL!! I don't think constant high humidity is neccesary,and could cause health problems...all the breeders I know(myself included) keep there's on newspaper w/large water dishes.The humidity in my cages is usually not very high,I do however spray several times a day while retics are in shed.They all shed in one piece,and I haven't had any Resp problems keeping them drier the rest of the time. If you are using a tank,I would reccomend a plastic cage instead.Plastic cages w/belly heat will hold humidity well,and are the best for Retics. These are my own opinions,but I hope this helps anyway.
