The more practical the better. The only devices you will NEED are as follows:
1)Thermostat (a must)
2)Heat pad/flexwatt
3)Water Bowl
4)Substrate (news paper, paper towels, cypress mulch)
5)Spray bottle (for humidity)
6)Digital temp gauge w/ probe(you can pick one up at a local pet store for $5-10)
7)Hide spot
I personally keep my bloods and all other pythons and boas in a very basic set up, i find they thrive just fine and enables me to keep up on sanitization very easily.
