I have 3 shiva skunks growing. I've been vegging them for almost 3 weeks now. I'm going to start flowering in a couple weeks. I have 2 40W 6500k flouresent tubes, and 6 26W 6500k cfl's surrounding the plants. Since switching to the tubes and cfl's, the SS's have gotten bushy and are thriving. I think the key with cfl'sand flouresent tubes is to use the right light spectrum. 6500k is full spectrum light and is necessary for flowering. You can use 5000k to veg,but you might as well start with 6500k. Also, key the lights close to the leaves, maybe an inch and a half to 2 inches so the light can penetrate through. The more light, the better.
