Hi Bill, all my Nuc Boxes have separate open mesh floors with a sliding solid panel floor when needed. and the entrance hole is 50mm on C/L up from the bottom, hope that helps Peter
I use the ET05 Thermostat Temperature Controller with a Low Energy 1ft 45w Tubular heater, in my DIY Cabinet 4ft x 2ft x 1ft 6in lined with 50mm Kingspan My one is just for Honey not for wax, But I am sure that your STC 1000 will do the job just as well
