thermostat question..

Thinking of a 3 tub system for 3 ball pythons..how many thermostats are needed for that? I'm new to the whole rack system thanks..

Its my understanding that you can run multiple strips of heat tape together as long as they are the same length/wattage so you should be able to run it on 1. but if they're different a wattage, you'll need to correspond your thermostats.

ie. 3 shelves of 4" tape = 1 thermostat
2 shelves 4", 1 shef w/ 11" = 2 thermostats

feel free to double check
