Like everyone else said the sweater box would be your best bet. I would strongly suggest the belly heat option is worth the extra $20. Im using the VE-300 to control my sweater box and my CB-70 6slot rack and its worked flawless I would def. recommend this thermostat. Heres a pic of my sweaterbox with dividers to give you an idea..I only have hatchlings in it for now but they seem to love it. They feed everytime offered and have perfect sheds for me so far.
