If you are a real cheap-ass, you can veg with red, or 2700k lights. It's maybe not the best, but works none the less. I know because I do it, but I only grow my plants 18 inches max in veg, so maybe for huge bushy plants you should use 6700k. You mentioned 190 something watts for one plant? In my opinion it should a really big, or really bushy plant, or that's just wasteful. Cause after running 200 watts for 2 months, and especially after price of bulbs etc. you could have just bought a big bag of weed, and been better off. Mind you, growing is fun, but it's important not to be wasteful, not just of money and energy, but of your time as well. @200 watts, you should be able to flower 4 medium plants nicely. A key to CFL growing is the fact that smaller plants need less light. In order to maximize efficiency of this lower light output, people have developed all kinds of tricks, that's why you see all these people S.O.G.ing, or tying down branches to make a wide-ass shrub, also reflectors, and use of mylar is common. CFL will always be inferior to HPS when it comes to yield, but what makes it better in my mind is the energy saved.
