2800 K Light?

[aaronnorth]

^ Green plants mean this is the spectrum of light that is reflected most, i.e. least used?
So surely, if you were to choose any spectrum of light, green would be quite low on the list?

Just something I remember from my school days (which was a LONG time ago).

A re-education though, is always welcome!

true, but i doubt ther is any tubes that just have green in the spectrum!! Even a tiny spike in the Red & Blue would be enough for the plants.
