Hey bro, you need to do some research. This is my first time grow and I got pretty much everything i needed info wise from this site. Also went up to the local book store and bought the cannabis grow bible, cash of course. So in my research this is what I found.
For CFL lighting you want to use the 6500k spectrum for veg, and 2700k for flower. These bulbs are energy efficient and relatively cheap. I have a 3 plant dwc setup and I'm using 3 42 watt 6500k bulbs right now. This doesn't mean you need a bulb a plant, but if you can, why not. You can get a pack of them at the hardware, lowes/home depot, for like $12. Also, you are gonna want to lower those bulbs to about 3 inches off the plants. That will keep them from stretching. Now for your timer. Go to an 18/6 setup. This means 18 hours on, 6 hours off. I wish I could tell you more about your water cycle and all, but I'm a DWC guy. I hope this helps and I will deff be checking in to see how your grow is doing.
Oh yeah, you can flower with CFL's. I don't know why that one guy put that. And also go with the advice of a fan and separate them into at least their own cups for now.
