Someone correct me though, Im very usually wrong. In my research for building a rack, I have seen it done various different ways.

Ive seen it placed directly under a tub (although if you have 10 tubs, it would seem redundant to only put it under one tub), Ive seen it placed on the extra part of flexwatt next to the tub near the attaching wires, I've seen it placed between tubs on the extra exposed flexwatt.

Also, is 3" flexwatt enough to heat up a hatchling if you are using belly heat? What about for sub adult and adult tubs? What is the most common uses for the 11" flexwatt tape? And what is the most common way to keep ambient temps in a room?

Justin from youtube suggests using close-air racks such as boaphile rhino or animal plastics, if you dont want to heat an entire room to 80 degrees. Because of the limited air flow, temps will keep better, and the flexwatt will do its job to keep the hotspot, as well as making sure the ambients are okay.
flexwatt does not heat up evenly. there is usually a +/-5% variation. i usually place my probes in the center on the flexwatt because this tends to be the hottest spot. flex watt isn perfect and is not designed to give a uniform temp. even a close air rack may not work in unheated room. my room is 70 and i need to insulate my rack with foam insulation to hold the temps.
