I'm not quite sure what you;re saying, but if you have your plants that are in Styrofoam cups under a 12/12 light, then they are already in the flowering mode... typically they should be 16/8 when vegging....so they can grow. they can be transplanted anytime, but the lights on dictate flowering or vegging.
