i have a 13 week old Panther Cham. I've read that some people turn all there lights out at night. Was just wondering if this also includes the heat bulb. I turn his uv light off every night at 8pm but leave his heat bulb on. It's on a dimmer stat so it sometimes gets brighter at night. Shall I turn the stat down at night? Or just leave it? Hopefully this isn't to confusing!
