I have tried this before after reading about it on Over Grow. I tried it and I do believe they got off to a faster start, although it was not a controlled experiment. I gave the plants 2 days of dark, and then continued on with 12/12 like usual and they seemed to produced buds a little faster. Like I stated it was not a controlled experiment so I can't be sure it worked but it did seem so. Just my input.
