you are going to want a hps for flower.. it will give you much better results gaurentteed--much more lumens than floros :P

vegging with floros isnt so bad, ive never ran a test on floro vs MH for vegging but im assuming MH just makes your plants grow faster.. since your plants arent flowering, using floros for vegging wont effect the quality only the speed of growth, but the same does not apply with hps vs floro because of the high amount of lumen being put out by hps bulbs

as for the conversion jibba-- i think they sell conversion bulbs that can plug right into the opposite ballast type check out this page.. there mightbe something for you here http://www.bghydro.com/BGH/items.asp...atus=0&Tp=&Bc=
