I have several Vision 432's and 422's. They are great cages but they are alittle tough to heat especially if you have them in a non-heated garage like I do. I only use a 60 watt household bulb in the recessed compartment for simulated light cycle. To heat my cages I kind of came up with a homemade rig using the ESU Thermostats and 100 watt infrared bulbs mounted in cat carriers for the snakes protection and a great fire safety feature as well. Alot of people use Pro Heat Pannels or Flex watt...During the time my females are gravid I will throw in a household heating pad so they can have the belly heat required. Here is a pic of my set up.....good luck! Richard "amazoa"
