changing light cycle in flower...

quick question.

right now my flower room is on 5pm to 5am (on/off). been like this for 3 weeks. i am not happy with this schedule. my question is this, would it negatively affect the flowering cycle if i were to change the lights by an hour at a time everyday until i'm at 10pm to 10am (on/off). so it would go like this: first day 6pm to 6am, second day 7pm to 7am, third day 8pm to 8am, and so on until i hit 10pm to 10am. what do you folks think?

thanks

I dont think it will be that big of a deal as long as they get 12 hours of uninterrupted darkness. Now if your growing 100 plants you might notice a yield difference heh
