RE: [GSAS-Member] Found! 8' flourescent light fixture

["Susan Welenofsky" <welenofsky@comcast.net>]

Isn't Mylar a type of thin metalicized plastic? Maybe that would melt? What
is the name of the hydroponics shop? Is it on Aurora?

Sounds like you have a plan then.  I have some Mylar from the hydroponic
shop ~175th (who also sells a PMDD trace mix) so I am sure I can spare some
although white paint (reflector) or aluminum foil (diffuser) also work.
