Your comments, particularly your reference to red and far-red light, seems
to indicate an awareness of phytochrome, but just in case, searching the
literature for action spectra of "phytochrome", a major photomorphogenesis
photoreceptor, should be fruitful.  I don't have the references off hand,
but if a cursory literature search doesn't give you what you want, email me
and I'll help you find some.

you're welcome,
