For plants, don't you also need some ultraviolet light? The white flourescent lights filter out all the UV.
There are such things as near-UV LEDs though! A recent Scientific American article wrote about how white LEDs are really near-UV LEDs with a phosphorous coating that flouresces white, so a UV LED should actually be cheaper...
The article said that the LEDs cost $1 each in quantities of 100,000. Well you can buy these white led keychains off Ebay from a variety of sellers-- AND THEY ARE GRRRRRREAT!
Slightly more than $1 each for a white LED with batteries and a keychain. We got them imprinted with the company logo and give them away, and people love them.
