Auto northern light blue?

Will be getting bean tomorrow. Its a free bean from the tude. Anyone done this strain before? What is the yield like? Anything to note? Should I go 12(12) at some point? Thank you for your replies! Have a great day! As Ever'

It's an auto, why would you go 12/12? Give it 18-24 hours of light all the way through.
