I disagree with Cole_Robbie on the issue of reflection. The back of my rack is lined with shiny aluminum foil and the front is closed with a white towel. The aluminum foil makes an obvious difference to the light level at the plant. Presumably the towel contributes too. (The ends are open for fans to blow through.) I don't have a luminometer to quantify the difference, but just looking at all the light that spills past your trays should be convincing.
