Video has been available since 2013. Can't imagine how much real research has been done when all you have to do is; Google rotogro and click on videos. I also assume that a couple of commenters on here have found NOTHING negative about using flatbed methods of growing. That only indicates the amount of research that's been compiled and clearly indicates at least three things in regards to the article you've identified. #1: LED lights are not yet viable for plants that flour (do your research), and #2: Cost of electricity is much less with Rotogro (again do your research), and lastly, seems like YOU should be investing in flatbed designs... is there anything you can recommend? LOL
