While dual-band works well, what I worry about is the fact that the one you intend to purchase shows 630nm for the primary red - not really good for good flowering like 660nm.

Also, that 100w panel is more expensive than my own 120w. I'd almost daresay you'd get better results with mine versus that. That one might provide better penetration power, but I think I'd win on overall yield.

Seriously, get Stra8 to get you some of what he uses before you go looking for the online specials. He's already got a great working formula down.
