HAHAHA! I was asking because I am in the market for another rack. I purchased a ballroom rack from boaphile last year. Sometimes the temp on the hot side exceeds the temp I want it at to keep the cool side at 80. My rack has two rows of flexwatt on the warm side. I have it hooked up to a herpstat4. In one of my tubs(unoccupied) I have 1 probe on the hot side and another probe on the cool side. My snake room is kept at 74 degrees with a room heater. I want to breed my snakes but I am concerned with the temp fluctuations. How many rows of flexwatt are in your rack? Gracias!
