There are a number of different pigments involved in photosynthesis that each are excited at different wavelengths, even green. The old notion that green light is of no use to plants is actually wrong, there just isn't as wide an absorption band at that point in the visible light spectrum. That's why plants grow best under a relatively 'full spectrum' lighting that contains a fair amount from the entire 'active' spectrum. I'll bet plants grow great under RGBW LEDs. But yeah, justin your absolutely right... plants require light from most of the spectrum to perform well.
We rarely hide the... uh, implements, around here. There are not many 'fish people' around the area anymore, really, and none that are reef tank keepers. So anyone that visits here is pretty much okay with the bong sitting on the shelf.
Hmm, I'd always thought it was 'active radiation'. Thanks Chris!
