We recently built a rack. Set up with flex watt and a herpstat intro. We ran everything for a few days before putting snakes in to fine tune temps and such. And I know that this could partially be the accurite reading a degree or so each way (waiting on laser temp gun, be here Friday), but there seems to be a range of 3-5 degrees difference in the tubs hot side. So they are reading between 88-93 ish. I am worried that the low one is only 88, but also worried that the hot ones are 92,93. It even got to 95 once before we put the snakes in. Is that too hot? How hot is too hot, where do you draw the line? Isn't 92 pushing it? It's the tubs in the middle that are warmer, maybe because of heat above and below it? Bottom one is the cooler one. Just don't want hurt my babies. Everyone seems to be doing fine, moving from hot to warm and vice versa. Ambient temps right at 80, humidity 54.
