I did the sea of green with the bubbleponics and had the Dual Spectrum II lights. the 6 plants are so very crowded at 5 weeks! I bent the ones over that I could bend over, and tied them over using big thick rubber bands. That made the limbs bent over produce buds or flowers growing straight up. I was a newbie back then but I had done hours of research and study. After 6 weeks of 12/12, and flowering, I took the big ones and after drying I had about 6 oz. of nice prime buds. No Giant colas tho, just nice buds. I adjusted my lights back closer, and decided to experiment and I continued to let em grow. I got about 6 oz more of small buds before everything started turning yellow on me. I've heard of and spoke to people who got a lot more from the sea of green style and they grew for like almost a year long.
Now I only try 4 fems in my 6 planter tank,in the corners, and I let them grow for 8 weeks and they get about 2 -1/2 to 3 ft tall but they get thick and bushy. I let them flower and flower too, and I get more.
Experiment and see what you get.
