Ok my two bp each have a 20gallon tank to them selves. I have my tank kind of in a dark place in the apartment and i dont open my blinds because people can see in. Any way would a day light help with the day night cycle. I know that these have UV is this beneficial for the snakes and will it create a better day night cycle? And how many hours should these lights be on with the timer like what time should it come on and what time it should go off?
