Would 75-80 on the cool side be a better option? I just recently switched to a rack and am still learning the in's and out's of racking warming and humidity. For instance, the tub in the top of the rack where the BP is stays sometimes several degrees warmer than the tub below that has the baby red tail. I worry about raising temps on the thermostat though because then the tub on top would be roasting while the tube below would be marginally better...if that makes any sense.
