I read the article, but something doesn't set right with me. LED's are narrow-spectrum lights. Don't plants need a broad range spectrum of light for photosynthesis?

wow.... the ignorance on this forum regarding LEDs is stunning.
...
I'm not trying to be mean or anything, but it irks me when people complain that LEDs don't support plant growth when they are using the wrong kind of LEDs.

You must have got up on the wrong side of the bed this morning. I can't figure out why you wrote such a condescending post and If you didn't notice, my question about LED's not supporting plant growth was answered very well a long time ago.
