I just checked my temps again, and this is with using a blanket ontop, on the end with the UTH, it is 92 right on the glass, If i set the probe ontop of the bedding on the uth it reads 82, about one inch up on the warm end it is 78... on the cold end, where Im running the 60 watt red night bulb, it is 77 about one inch up, and in the middle of the tank, the bedding reads 76 degrees... and this is all with a blanket on..now keep in mind, it seems my ball is a borrower. he never uses his log, he likes to borrow under the aspen, I was gonna buy the turf bedding today, but I dont want to do that, seeing on how he likes to borrow...thanks
