To the best of my knowledge Bugbee found no morphological effects but didn't quite specify what was the factors he looked at. But lets get this straight: he is one researcher out of many.
In general horticulture green response means more fibrous type growth of support like structure: it promotes more woody growth and is basicly an intra cannopy response; it tells the plant that the part under green light that its not top growth so better to produce fibery growth like a branch. This is nice for yield but is it any good for bud quality, terps and flavors? I doubt that.
I think many who see leds as inferior due to quality of smells, missing volatiles smells and such, are getting these results cause modern growlights depend too much on green and 660 leds for efficiency, rather than trying to get a more balanced approach. To me its insane the whole idea that any red between 600-700nm works the same for the plant when there are clear and differences in how light is processed depending on if its higher or lower that 650nm.
I believe the best approach for a good producing spectrum is wide blues, low to mid green (depending on what intensity your grow at) and wide red with at least as good coverage between 620-640nm as +650nm and at least some type of targeting of 680nm.
