i have grown with floros, mh's, and hps. And from my experiences, hps gets the best budz overall. With MH and HPS combined, you get even better budz. Now, i only use floros for cloning purposes, otherwise they are useless for me. For a personal grow you should get a 250 mh, youll have a bigger yield, with more abundance of trichomes. MOnthly electricity shouldnt be that BIG of an issue, it costs a few bucks, a few bucks thatll make ur buds that much better.
