Lights on or off when cycling?

You can but at the same time it means the nitrate and phosphate are being taken up by the algae and not by the bacteria, which slows down your cycle

Lights on, these days with seeding products the cycle is super quick anyway.

Super quick is still usually about 2 weeks, if you spark an algae outbreak in that time it'll take longer

Well heck lights off then, I'm convinced,
