My plants are a bit over vegged, and I have a flowering light arriving end of week, beginning of next week. I'd like to switch from 18/6 to 12/12 as soon as possible, what would the effect be of starting the 12/12 with 6400k cfl's, and running that way for around 4 days? Any other tips for a smooth transition into 12/12?
