I was curious to the effects on darts when the lights stay on longer/later than normal, and some days the lights go on later... Is there a health risk? I could understand it will throw off breeding for some more sensitive species, but will it have a more significant health risk as well? All my thanks! I need a timer, lol! Sometimes I fall asleep on the couch and wake up at 7am and the lights are still on. There is no heat risk, but... Sometimes I sleep late and forget to turn on the lights until late afternoon, early evening(which I like, but doubt how natural that cycle is...). All I am saying is that I am terrible at maintaining a consistent cycle.
