see i think you might be right, but i also know plants have been evolving and adapting far longer than humans have been here and doing "science" science does not explain everything,and there are many things plants do that science does not understand or even comprehend, like why have my plants turned to face me instead of the light after i moved them out of the tent for a couple hours! i had the liner out to clean and was sitting at the computer no light sources anywhere near me besides my monitors, just me and some music playing low, i turned around and they had tipped in my direction rather than the hps they were only 6 feet from bout 1o ft from me! kinda creeped me out and i cant come up with any plausible explanation, , my point being is despite our sizable knowledge on plants we dont know everything, so im always open to new ideas and concepts, i think back a few years to when i was first introduced to how to feminize seeds with colloidal silver and how totaly nuts that sounded but its a common tool i use regularly now, or how appalled i was at the though of washing my meds in a tub of hot then cold water!! i remember thinking "right ! thats a great way to ruin my crop!" now its mandatory, so maybe full spectrum lights will be the everyday thing i wont be without who knows!!
the videos i saw on another bud mag site showing a side by side vs a 1k hps looked impressive!
