I have one rack heated with a heat cable. Its a vision arboreal rack. Personally i dont like it. The reason being, is the tubs are taller than most and harder to heat from the bottom, so i've had to modify the rack to make it work for me and the snakes that occupy the rack. However im sure a vision rack with tubs for terrestrial snakes would work well! Animal plastics works with heat cable as well for the racks they build. Good luck
