wow, 1.26 g/w is fantastic...even if on power draw, not output. If you can get into that range on output (357 vs 180) then I see no need to ever use HID again! nice work, hombre...
Fantastic, incredible, fabulous, etc., yes. The output of his grow is 180W/light though, because lights can't magically put out more energy than they draw. If he had used CFL a similarly false argument could be made, whereas with HID, people list the wattage of the bulb/ballast, not the 15-20% higher actual draw (400W drawing ~480W, 600W drawing ~700W). This g/w should only be compared to his previous result, or the results of those with similar veg cycles, but with a 3 week veg HOLYCRAPTHATSAWESOME pretty much sums it up.
@dunit Any chance for some dried pics?
