I'm in the process of getting my new rack up to temps before moving my snakes, I picked up the 3 high sub adult rack from Cserpents and moving them from tubs with the UTH taped to bottom. My question is how high are your thermostats set to get them up to a hotspot of ~90 degrees? In my tubs I could set them to 92 and the tubs are almost perfect, in the rack it's been sitting with the thermostat set at 96 and not getting anywhere close.

Same room and using a herpstat
