My setup at the moment is made up of a UTH on 24 hours; There are also 2 bulbs in the viv - one regular 60W white incandescent which is on a timer to come on for 11 hours during the day, the other a 50W infra-red bulb which is also on a timer to come on the other 13 hours at night. Both bulbs provide the correct temp range (the infra-red making it a couple of degrees warmer than the white).
My question is whether I would be better to just have the infra-red on for 24 hours and remove the white bulb. Or is it better to have the day/night cycle of the 2 different bulbs?
Also, is it a bad thing that the viv is a couple of degrees warmer at night (all temps are in a safe range)?
