That was quick, thank you. I have seen a couple HID set-ups before and so I am not sure what the optimal yield should be for CFL? There might be close to 3/4oz on each plant as they sit. My friend got a book that started this whole thing and the guy got 8oz with 42W bulbs on three plants and around appox 4,000 lumens per sq ft and we are around 2,500...so we are going to build a new rig and hopefully get closer to 5,000 lumens per. But even at 2,500 per I was expecting more yield so there are some other issues i think.
