Dude make it worth your time, you can send them out as soon as they show there sex, but give them 2-3 months of good veg, then 12/12.
Now just after bud set (approximately 3 weeks) reset timers to 13 hrs light/11 dark. That really kick them into overdrive, but only for 2 weeks, they need the other 3 plus weeks to to fully develope.
