I'm with Opie Yutts there. Almost all of the led grows I saw messed up at some point or the other. I was reading pages after pages of good info and then there is a CFL involved, early flowering, change in nutrients, a friend took over for holidays and let them die, one yanked them out being paranoid, HPS got introduced to save the yield, etc. I would have been happy to just hear that it takes 2 weeks more to have the same yield, or something like that. Still I hope people continue to do their grows, at some point there will be semi-scientific data.
