hey guys im setting my reptile room this week, just a few questions. i will be doing a rack system, is belly heat recommended for every ball python size? meaning should i use the tape in very rack from hatchling to adult? what temp should i set my heat tape to? also as far as ambient temp, i live in Florida so in the summer it gets hot but some days during the winter it gets pretty cold, i use a programmable ceramic heater to keep my room at 81 all day, is this acceptable? and what can i do to keep my humidity at a right percentage for them?

Thanks!
