give them less light, the exact same thing has happened to me, i had no idea DLST had started, 10 pm is too late for me past my bedtime so to speak. i was liking the 10 am thing but i am not usually able to get anything done in the morning before 10 anyhow. i once read an article about finishing faster by having a 12 hour dark period and a 9-11 hour light period, plants finished in the same amount of "days" but over a shorter span of earth days. i was about to ask the same thing ansd ask about thins technique. i still am but thought i weould put it here too.
