quad or tri band?
Depends on what you are trying to grow. If you are growing buds on cannabis, 660nm red is what does it. Every led you add that is NOT 660nm is going to cost you bud in the long run. 4 band UFO's aren't better for flowering cannabis; they're less efficient.

I'd go with all 660nm reds, with just enough 465nm blue for clocking /phototropism. (8 reds to 1 blue or so. This is a fairly common UFO scheme, just don't let 'em palm off those old, unwanted 630's on you. :smokin You can add other wavelenths easily with a CFL or two, and/or other types of inexpensive lighting, if you feel you might be missing something.

More bands is not better. More 660nm IS better.

And yes, most pot plants stink. The last strain I grew smelled worse in veg (like a dead body :wtf than in flower. A carbon filter/fan combo's the only thing that works for me.

You will need odor control. Folks won't need to come downstairs, they'll smell it at your front door. You'll need to take care of this within three weeks or so, unless you've got a real low-odor strain going.
