Very well said. :thumbsup: And noted.

I too, am a more "in your face" kinda guy.


"What a waste of PHD. Those that can, do. Those that can't, teach. "

Dude.......So he disagrees with you ...he must be a moron. He left the industry because he enjoys teaching. Thus I found myself in his class. Well actually I am only in the class cause a first timer friend wants to go hydro..I am a dirt kinda guy but that is neither here nor there.

Moreover since this was a hydroponics class and not a grow pot in you bottom dresser drawer class, his comment and opinions hold more water. Cucumbers will not grow properly without green light for example...(a fact bandied about on this forum regularly). So since he is teaching a class on growing everything(hydroponically) there is an example where a 2 color light would not work properly. :jointsmile: I am sure that an extensive study would find many more examples of terrestrial plants that have specific wavelengths of light required for one phase of development or another.

The number of people on this forum alone commenting on UV light and its effects on resin production should give other readers pause.....
khyberkitsune the tone of your response...speaks volumes...however your insist are invaluable. I look forward to some more spirited debates in the future.:jointsmile:
Greenmain Reviewed by Greenmain on . Drowning in conflicting plant graphs - help! (LED) Still trying to design my LED light through clear understanding and not just mimicking. There is one photosynthetic response curve that shows yellow light has more effect than blue light and that green, while lower, is almost as useful. Other articles say green light may stunt plant growth and that yellow is not much more useful (despite the huge success of HPS). Then there is the photosynthesis action spectrum showing that violet/purple light (400nm) has the highest absorption peak Rating: 5
