Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis.

Really surprised no one mentioned this but CMH is a lot more efficient than HPS, many people get same results from a 630cmh as a 1000 hps. And I think he said he has 2X 1000W CMH. So from what I can see, that's probably the biggest factor. Either way I can't see how this plays out!
