As for your lights. I would pay more attention to the lumens that the plant will recieve. If you can supply a min. of 3500 lumens to the plant during veg you should have a nice grow. If you can up those lumens during flowering to a min. of 4000 lumens you should have a decent crop. I always suggest using more CFL's than you think you need because they are not quite as powerful as an HID light. Another great tip for CFL growing is to supply light to the sides of the plant too. I know a lot of people that say it makes no difference but the light from the CFL is not very powerful and does not reach the inner and lower portion of the plant as well as an HID light.

I cuurently have 40,000 lumens in CFL's in a 3ftx4ftx7ft area and two beautiful full figured ladies. This is my first documented study on CFL growth and I think many people will be suprised when they see what is being produced by CFL's only. Grow log to come soon....
i hear what your saying about the lumens i seen a 250w cfl on ebay tht gives off 19400 lumens would tht be really tht good?
