Yeah you can do it, just the results would be much better with HPS. Keep a log, I'd like to see how the heck you are going to fashion that many fixtures in one area, think about how many times you will have to move them....lol....take pics! Look into LST so that you can have an even canopy so more light reaches the buds. Think about the investment in bulbs too....(day light ecos are 9.00 for two) (kitchen and bath 6.00 for two). In your case you many want to buy the tubes by the case....And with all adustments.......Just wondering, are those fixtures all double lamps/tubes or just one? Oh, and I've been using kitchen and bath tubes for flowering, that is why I mentioned it. Good Luck! :jointsmile:
