Ok so today I went a little crazy and decided to switch to coconut fiber husk. It looks good and natural, but since it's a thicker substrate than regular newspaper, I have a few questions. I know I asked about where to place my probe on my rack, but what temp should I set the thermostat considering the rack doesn't sit directly on the tape, and now that I have substrate the snake sits even higher. So if I want temps of 90 degress for the BP's what should I set it too?
