Hello everyone...My cousin has a 72 bow and we're trying to figure out that kind of light to put in it. 48" combo fixtures are too wide to fit in his canopy. I was thinking of putting retro fixtures but I have no clue which one are good. I also want him to have 2-250W 14k Phoenix MHs and some actinic supplementation but just for dawn and dusk affect. Can someone guide me into the right direction. Thanks in advance, Fortunato
