I am trying to figure out how to run flexwatt heat tape in a way that would allow me to use one t stat? Is this possible? I was reading on other threads that some people are running three or four racks off from one tstat?

should the flex watt tape run under the tubs for belly heat?? or off the back wall of the rack? I am trying to understand what would be better for the snakes. I don't keep my ambient air temps in my house very high... in the winter it stays around 70 in my house and in the summer about 75 and I am concerned that during the winter I will have to provide another heat source to keep my temps up.

Right now I am using glass tanks which is all well and good... my temps stay pretty good but I am using heat lamps which I don't like... bad for the humidity etc etc. So I want to leave out the heat lamps and just use the flexwatt tape.

Any Ideas?
