Because I provide my snake with a hot spot of 90 degrees and I find that to be too hot for ambient temperature.
And I order to get the spot under his hide on the substrate to this temperetaure I need to bump up the heat from the RHP to a much higher temperature so that the heat reaches to the bottom of tge cage and through the hide.
And if the heat panel gets too hot my BP will burn itself because he climbes to the top easily and he does it constantly. That's my problem.
I don't wanna cook my snake or burn him or let him freeze.
That's why I said it takes me ages to figure the parameters out.
