I keep seeing this said and it simply isn't true. Just because a light is of a certain color tempature does not mean it will support plants. White point has nothing to do with spectrum. You must be sure you are getting full day light spectrum LEDs, which most of the decorative type LED
lighting systems this guy is talking about do not have. LEDs by nature produce light in very narrow spikes of bandwidth. It takes a good deal of engineering to even get white light out of them, and takes a [moderator edit] of allot of engineering to get the broad spectrum needed to grow plants. Simply being a bright shade of white is not enough.
