I've also read people who give their plants sometimes up to 72hrs darkness prior to flowering induce flowering faster than someone who just switched the timer.

The way I did it was at the end of the last day of veg, I left the lights off for the remainder of the following day, so it was like they just had a really long night, and then flipped em on. My plants sexed in two days, but I don't know if that had something to do with it, or the fact I vegged for 9 1/2 weeks. So I figure if you were to gradually decrease light, the plant would start producing what it needed to flower a little sooner when the lights were say running on the 14/10 or 13/11 cycle for that period of days, so when 12/12 hit they would be ready to bloom.

hmm...
