Just doing some calculations in my head, I can see that 3 of the 63W units placed side-by-side in a row (long axis of the units perpendicular to the long axis of the grow tubes) would probably be a nice coverage for an AeroFlow2 18, which is the system I'm about to start using. I've already got HID set up, but now I'm thinking about trying LEDs once I get a complete grow under my belt.
