Two questions. First, is there an optimum length to veg? Seems to me that the longer one keeps a plant in veg then the greater the yield. But is there a point where that doesn't apply? I'm a new grower, just two plants right now, each in a 6" pot but space is not an issue. Will transplant eventually to 5 gallon each. Second, I'm using six 26W/100w output CFLs in reflector clamp lights, a mix between 5000k and 6500k between 2" and 6" from the plants. I will reposition as they grow ensuring to hit all parts of plant. I could add more. Is there a point where more doesn't matter or is more light always better? When I go to flower I'll change to something around 2500k and will position lights above and around plants. Thanks in advance for your help.
