Thinking about getting away from lights as a main heat source. I have a hand held laser thermometer also on top of the hygrotherm. When I use the laser I'm getting a bunch of different readings from all over the enclosure. I'm tracking the laser only reads surface temps but what I'm really wanting to do is to create an all around steady ambiant temperature even in the shade.

1. I have the exo-terra 18x18x12 enclosure. I would like to stay with the exo-terra brand. They make three different types of cables which one should I get?

2. If I attach it to hygrotherm would I still need to hook it up to a thermostat, and how long does it take to warm up? Or should I use it with a thermostat and have it stand alone and if so what brand thermostat?

3. How would I attach it to the enclosure? Inside or outside? Do I need to any additional supplies? Do I zigzag it?

4. As always pictures would be awesome for ideas.

Thanks in advanced
