No, that is only for switching to flower. It 'shocks' the plant into flowering, basically shaving a few days to a week off of the flowering stage. You should just adjust your timer so that the lights come on at the same time, but stay on an extra 6 hours.

I wont give up on you as easily as Ocotillo, though I don't blame him. You really need to read some basic grow information, because most of these questions should have been answered before you even started your grow. For all I know you're in the middle of reading it right now. If so, good job. :thumbsup:
