Hello Plant People

I've received several replies to my inquiry about obtaining a Rohm and
Haas No 2424 blue light filter for student research projects.  A few
people asked for the information, so here is a summary:

Gerry Dietzer wrote "Kinetic Artistry in Silver Spring, 
MD (http://kineticartistry.com/).  Although I doubt that they have or 
can help you with a specific Rohm & Haas acrylic filter, they do have an
extensive collection of Roscolux and Roscolene cellophane filters that
can be applied to an ordinary plexiglas sheet to give you whatever 
wavelength selection that you might want.  The cellophane is just as 
good as the acrylic that is made from the same dye"

Robin Wynne-Edwards of Qubit Systems Inc. (www.qubitsystems.com) can
sell an acrylic blue filter for a very reasonable price.  It's the same
material that they use in their Ps teaching system.

Thanks to everyone!
Carol
