"Plenty of this light was in the green area so not absorbed by plants." This isn't true. The majority of light from an HPS light is green, yet huge crops are grown using that light all the time. Plants utilize almost every visible wavelength (and some invisible wavelengths) to some extent. LEDs generally just focus on the wavelengths that have been determined to be efficiently utilized. It is all however still 100% crop-dependent. Some plants simply hate LED lighting because of the missing spectrum (like my orchids.)
