Was just poking around his mjgrowers.com sight and just read these two little paragraphs:
"When blue light is turned on during the dark period, plants photosynthesize but their flowering isnt affected. This results in more growth as the plants produce more sugars. Before LED lights it was difficult to create a pure blue light. Instead, most of the time other spectrums were filtered out, which can be an inconvenient process. Try using between 20 and 40 watts of mixed blue light per 1000 watts of regular light. I have done only initial experimentation with this so test this in a limited way first. I suspect that the additional light is an efficient way of increasing total yield"
"Aside from red and blue light, plants also use orange light for photosynthesis. I havent experimented with them yet, but orange LEDs might also help increase yield and probably can be lit continuously, just like the blues. More on this as the news breaksor at least, as it fractures."
Here's the link to the full page:

Has anyone heard of anything like this or know of anyone doing this? Has this been discounted yet and how can we convince one of you fine boys or girls with some blue LEDs to try this?
