These figures are from an old hydroponics source. Unfortunately I
know longer have the URL. These figures, represent the percentange
of light reflected.
Mylar 90-95
Flat white paint 85-93
Semi-gloss white 75-80
Flat yellow 70-80
Aluminum foil 70-75
Note flat white paint is better than semi-gloss. Does this suggest
wrinkled tinfoil is better than non?
Hope this helps.
