I've grown with LED's before and yielded smokable bud, I can't recommend a better for side lighting but you need a 5,000k cfl. Plants respond very well with Full Spectrum, LED's alone just don't do it. This site has a lot of great info for LED grow logs check out SSnStealth's work with the Procyon. I am very intrigued by these lights, I just don't like how they don't give you the angle or the luminous intensity rating's on their diodes. Best of luck, I'll be taking a seat.
