Lighting an orchid closet - fluorescent or LED? Otherwise?

[Ray]

Naoki (and anyone else interested), take a look at sevengens.com. It is a website for LED horticulture.

I have been communicating with Don, the owner, and they are finding that plants respond differently to individual wavelengths in some cases, which may lead to a greater productivity.

So far, the majority of their work is with berries and vegetables, but they are developing emitters and controllers that allow one to vary the spectrum to suit your needs.

Interesting stuff.
