I have a small fluorescent light over top of my snake's cage that I only ever turn on when I need to see in. Normally the blinds get opened in the room and light comes in so this provides an OK photoperiod. However I may move him to a place in the house where there is not as much light coming in during the day. Should I put the fluorescent on a timer so it comes on/off or is it a total waste and the snake won't care one way or the other?
