in a couple of days im going to be buying a thermostat for my enclosure. i have 1 female ball python and only one enclosure and its going to be like that untill i get back from basic traing and tech school. im leaving my snake with my sister till i get back and she is going to be taking care of my snake. i had my eye on two thermostats. there is one on big apple herp but its the on/off t-stat and a ranco from reptile basics. its only 20 dollars more and i know its worth the investment but i just wanted to know whats the difference between the prewired and the non-prewired?
