Hi GG. I was just wondering about the range of light you have with you cfl's. I also use cfl's for part of my setup inside of course. It looks to me like those bulbs might be better for flowering your babies. For veg you want 5000K to 6500k lumens. For flowering it is 2700K.
Here is a link to the CFL club with lots of info on lumens and light colour you

Now I might be wrong but it looks like those are smaller bulbs. If interested take a look at my contrapition I made up for cfl's in my indoor log. It works great and holds the bulbs sideways which makes the max amount of light available to the plants, as more comes from the sides versus the ends. The link is in my signature.
Your set up looks boss! What kind of venting and cold air return do you have in that beauty? (sorry I went and read it again, make sure you have that set up before you put your plants in there or you could kill them quickly, temps can climb quickly with cfl's.) Good luck and happy growing. Hope this info helped you.
