They'll have that same efficiency with artificial lighting too… At least until our grow lights stop emitting light in the green spectrum (not something I expect to see anytime soon).
- kibwen 6y agoGrow lights are quite good at only emitting light in certain parts of the spectrum, and have been for some time now.
- falcolas 6y agoJust looking at some spectrum charts for grow lights... They certainly vary, but not in any uniform fashion. There is an exception to this: there is a standard LED graph which shows up quite frequently, identified by it's peeks in the deep reds, yellow, and dark blue, with a marked trough at cyan.
- ryder9 6y agoalmost like the people who designed growlights knew that and the technology that limits spectrums useful to plants has existed for at least a decade or more with LEDs now they're even more efficient
