i use 4 ft flouros in my vegg room and love them you just have to have enough and use them right. check out what i can grow under them. you should use the flouros for veg and hps for flower. mh is also good for veg, although much more powerful it is hotter and costs more to run. you don't need to scrap the flouros just get a few more and use the right tubes. my favorite flouro tubes for veg are these. they kick ass as you can tell from my plants.
