Hard to tell, it's still in the "experimental" phase...won it off Ebay last year (or was it 2008?) thinking I'd made the deal of the century: quality UFO's can go for as much as $800.00 and I paid $135.00 for it (I won't bring up the triband fiasco - Chinese seller gave me the run around when I wanted to return it...).
Anyway, because of the shape, the sprouts sometimes grow sideways to get to the blue LED's...which is why I still entrust vegging to my power CFL. Mind you, with a couple of Blue PAR38 LED's flanking the UFO I
think I'd trust an all LED grow from seed to bloom...
Just beware the cheap knock-offs, I'm learning the hard way that you get what you pay for. If the reds aren't 660nm and the blues 445nm (or within that range)
run the other way those lights aren't worth the dough! ;)
I confess, I'm after a bargain like the next guy :D but with a bit of research it's possible to save dough and get appropriate lighting:
