It depends on what size tubs you have! I used the 4" flexwatt for my 41 quart tub rack!
This is up to you! You can wire them in parrell or with one piece of flexwatt for the whole rack if you want just one plug or or you can wire them seperately and plug the into a power bar then plug the power bar into your thermostat or dimmer!2. How should I cut it? Should I cut single peices of it, and put down a seperate cut of the flexwatt for each shelf? If I do this, is there a way to wire all of them together so that I only need 1 plug? Or will I need to wire them all seperately and plug them all in seperate into an outlet?
You run it across one shelf then down the side and across the next shelf and so on! You need to cut out a hole on each shelf to feed the flexwatt through!3. A few people have told me to run it throughout each shelf. How is this done? From side to side, or front to back? How will I run it from one shelf to the next?
I use only belly heat as I believe its better for the snake but some use back heat and it works fine for them!4. What is better, belly heat or back heat? I know belly heat will help with digestion, but so many people use back heat now, it seams like many are switching to it.
Make sure your connections are tight and insulated! Use a dimmer or thermostat so the flexwatt does not overheat!5. Anything else I need to know? I just want to make sure I understand EVERYTHING about flexwatt heat tape before I go burning my house down or putting a snakes life in danger.
