this being my 2nd grow, I also did a few 12/12 experiments. I noticed that the plants that made it through the process (1/4 female) the plant was about 3x more bushy then the same strain starting out from 24/0. I'm about to start my 3rd grow and plan to throw a few in the flower side of my cab and see how they go. I'd say its worth a shot, but not for my whole group just yet.....
