My guess is yield would go way down. Using 4'x4' grow tray as an example,( 'cause that's what I'm working with now) 2 Procyons would not cover it. 1 Ti SmartLamp will not cover it (at least for MJ) and if you even look at the 600HPS you'll find light coverage drops off in the corners compared to the center of the tray.

Possible that a combo of LED and fluoro might work, maybe 2 Procyons and 2 200wattCFLs. Dollar for dollar the HPS is probably the way to go, but for me I'm up to trying to light 4'x4' trays with 1-Ti SmartLamp (300watt LED) and 4-4' T5s driven to VHO levels (340watts T5) for a total of 640 watts of hi-tech hy-bred.
