back heat?

i am going to make a new rack for lid-less 41 qt tubs and am going to be running 11" flexwatt as back heat. i was just wondering with ambiant room temp of 78 deg what temp is evryone setting there herpastat useing backheat to get a 91 deg hot spot???

can't go by what others are. you need to get a way of measuring your temps and also check each level of your rack. a temp gun is a very important piece of equipment. and ones like the pe-1 sold by pro exotics will do just fine and the price is on the lower end of temp guns. I tested my pe-1 with my high end fluke temp gun and it tested the same. since it's back heat. you don't have a hot spot in which the snake can lay on like belly heat. so I also check with a thermometer and when the snake is laying in the back of the tub. closest to the flexwatt, I will check her body temp with the temp gun. hope this helps you more than me saying what my herpstat for my backheated tubs is set at.

ya i know i will need to check temps...i allready have a temp gun for that...i am just looking for a number to start out at before i start fine tuneing

Start at 91. Dial up from there.

Remember flexwatt is not intended to be used past 100ºF so that is the stopping point. The exact setting will vary but i would think that back heat should work fine.
