Emily, I highly doubt you are going to find spectral aluminum at a hydroponic shop, but check it out.. maybe them shops are mose sofistacated out there
. I have not found one out here that even know what it is
whare you will find it is at a sheet metal supply place. there are several names for it everbright being one. the stuff you will find in hydroponic stors is mostlikely polished aluminum which doesent even come close to the reflectivity of spectral aluminum.
