blue light filter

[Carol Auer]

Hello

I am trying to find the Rohm and Haas acrylic plastic No. 2424 that is
used to transmit blue light onto plants.  So far, I've only found a
company that wants to sell me a 6' x 8' sheet of plastic for a
ridiculous amount of money.

Any suggestions? I'd like a piece about 12" square.
Thanks
Carol
