200w of light is just fine, Depends what you want, how you growing? 30w a sq. ft. is ideal, but you can do well with half that. 60w daylight cfl is equivalent to almost 240 w of incandescent. Biggest cfl we have is 23w, unless you run those gigantic growlight size, Yours? If you have the special cfl grows with actual 60w (not equivalent) you will be able to grow a big one. On the other hand if you are running 60w equivalent cfls (18W) then well yes they will be small. For an example, we grew a low yeilding Strawberry Kush plant with 2x 23w daylight cfls, and got 3/4 oz. of dank Strawberry bud. Normally yeild 2.5 oz in the growroom, but bud finished great. Grow cost like 10 bucks including clone (free), equip and hydro. Still takes 10 plus weeks of flower though....
