2 shop lights will be fine to veg those plants with but you need to keep fluro tubes about 2inches away from your plants. for flowering 4 plans i would use 2 red tube bulbs apeice.You definitely wanna get better lights, the difference is huge. I suggest a 250 hid light for 4 plants.
my plants dont seem to be as stretched as the ones in his picture and i dont have to hassle with moving a million cfl'sCFL's would work better to veg those clones instead of floro's because the floros make your plants stretch too much, cfl's will make them more dense and bushy.
