interesting. I ask this question because I see big companies selling their led grow lights for very expensive prices. Now I know I can get them alot cheaper if i know what spectrum's are best. thanks againyour quick question doesn't have a quick answer, really.
plants utilize all spectrum ratios, seems to be the growing consensus. LEDs typically scale from someting like 720-730nm (infrared) 660nm (deep red) 630nm (red) white, either 3000k or 5000k, and 460nm blue. I guess there's also some convincing arguments for UV light at like 400nm. However, multi-spectrum pure white LEDs are gaining popularity.
