change the timer on your next off cycle. eg if you are on a 18/6 currently, like lets say 5am till 11pm when it goes past 11pm in its off cycle chnage it to your new 12/12 be it 5am-5pm or 7am-7pm whatever you want. you can do it slowly over the coerce of a week or two like nature does in 15 min intervals a day but the plants don't care. one stop shot, get it done and over with. Good Luck!

Hi there So, as you to into pre flower. You want the most even temp for the 1st few weeks (pre flower) so, I'd have lights come on at the coldest part of your day. And lights off at the hottest. Or whichever way gives you the least temp fluctuation

I’m trying to keep the midnight point when switching to 12/12 by giving the last day of veg several extra hours of darkness and the same amount on the first day of blooming. For example, if the midnight point was at 14:00 (no light from 11:00 till 17:00): the next day I switch off the lights at 8:00, and turn on at 20:00.
