Help Me Identify My Strain!!

[Delta.9]

I have a perfectly dark closet to bring it into before sunset. I'll wait another week before starting because I just topped it today and want it to heal prior to starting to flower.

yeah give it 12 hours on 12 off

If for some reason I can't bring it inside because I can't make it home one day, will this completely screw up the flowering?

Also, does it have to be exactly the same amount of sunlight each day? I mean to the minute? Because the sunrise and sunset changes by almost 1 minute every day.
