I was just standing outside thinking about this very thing. My next round which will be introduced into flower will be in 6 weeks or so, I just cloned. I run my veg 24/0. The next time I will cut back and slowly introduce 12/12 in about a week, counting that week as the last week of veg, not the first week of flower, which you can only do when they have 12+ hours of night. I will cut 1.5 hours a day until the last cycle on day seven which they will be on 13.5/10.5, then darkness for about 24 hours and on to 12/12. I think it will be less stressful and maby help the hormones in the plant to switch over to flower as it will sense the diminishing days, I think... And if that is true, then I should get flowers earilier and less of a stretch. Seems almost more natural to spread it out longer, but I know I would lose some growth due to increased night hours, but it could be possible that your babies might thank you for the ease into flower with a larger yeild??? Looks like I'll do a grow log and compare my notes.
