I however do not. My lights come on at 6 when i wake up and shut off at 7. I leave the house at 645 and dont return till 5. In the summer, its light from 545 ish to almost 10. In the winter its not light untill 8 and gets dark at 5. If i were to follow the daylight hours, i wouldn't be able to feed.
Bring me to my point, it kind of depends on your schedule as well. I'm assuming Carol is home during the right time of day so she can feed and everything which makes it possible to follow daylight hours. I however can not do that.
14 hours should be fine

I've never had a problem
