All I know is keep my humidity around 40 on avg and when he sheds I bump it up to 60-70 as often as I can.

Aspen i I think is the best ( it's what a few friends use ) and I also think people go way over board about things here.. Keep ya hot side 86-90 ,humidity around 40 -5o on avg,regulate the temp on your heat pad and there shouldn't be any problems. It's not that hard.
