Ok Your also twisting my words, I never said use a repitmed thermostat either =/
Secondly, most people dont live in a house with 80-85 (usually) maybe he does, I dont know
Most peoples room temp is mid to low 70's So requiring a Hot spot of 86+ would be preferable. IF you have an entire room adapted to heat from mid 80's year round and day round, that's fine I KNOW hot spots arn't 100% need'd always but then you need a higher ambient temp them most peoples live in. So if the average snake keeper as a pet has a snake in ambient room temps with no hotspot it'd likely not be the healthiest of animals.
Im not knocking or thrashing anyone's method, BUT i believe he needs a Hot spot of 85+ for his snake to be healthy IF hes not giving an entire room (which most people do not when they have 1 snake)
