flexwatt questions.

What would be a good size to put in a 41 q rack? And how do i install multiple lengths of it?

also what kind of thermostat to use with it?

we use 11" and we have two lengths so that the bottom 5 bins one can be set a little higher if need be. We use the herpstat II.

cheers

oh lol its wired as two separate pieces. and plugs into its own channel on the herpstat II
