I know VT uses a T5 for Veg and swears by it. Not sure at all though how much area they cover. I have MH/HPS, and it's my first grow anyways. lol. I definitely have been told T5's are find for veg though. Not sure about flowering though. From what I'm told is the more light the more bud, but I'm not sure at all about using them for flowering. I've heard of some people using CFL's, but I'll stick to the HPS.I have a spare 3x3 tent..is an eight tube 2' light enough? I'm used to mh and hps. Thinking of saving on power and another loud fan.
They should do the job then Coho.Its just veg. I get a kick from clones, ceeds and grafts.
