Ok so a 2 x 3 x 5 = 6sq/f of grow space.
If you run 3 Vero 29 3500K at 1.4A (1400ma) your getting 546 PPFD which will grow great Cannabis.
If your in the USA Vero 29 are cheaper than where I am in Canada.
That build above just add an extra driver and would suggest a 36" heatsink.
I suggest you head over to youtube and check out GrowMau5 he has a series that will teach you all about DIY COBs very i depth.
