Default lights or no lights

Hello

I'm new on here and the hobby, looking to have a couple of questions answered. I started my tank on the weekend, it's a 90g reef with a 38g sump. I was wondering if the lights in the tank and sump need to be on during the cycling period, if so, for how many hours a day?

Thank you
