I use to have my temps higher at 92 degrees on the hot end and I had a few snakes that werent eating including the Pastel male that I got from Tracy from VPI. I emailed her for some advice I described my whole set and temps and she said they were to high I set the temps as she recomended and in less than a week all my balls were eating. I asked her why the drastic difference in temps and she said she couldnt speak for the other breeders but that that is what works for her. In my case her way works for me so that how I manage my temps for my balls.
Like Adam says its not that Tracy is right and others are wrong its just that thiers more than one way to do things and get the same results.
