Dear Plant-eders,

I have a number of student groups wanting to do experiments investigating the
effects of different colors of light on plant growth.   I've not been satisfied
with what we've used in the past to try to do this -- does anyone have
suggestions of good sources for colored films/gels/whatever to use to filter the
light?   Or are there light bulbs out there that could be used?   I'm not
finding stuff in the Carolina catalog, Wards, etc. but may be looking in the
wrong place.

any help is appreciated,
