I have gotten differing opinions from everyone I've asked. Most have told me that flat white paint reflects light better than anything else. Some have said that mylar is the way to go. And a few of my friends say that foil is just as good, but make sure you leave the dull side up because it reflects better??? I've already got the main perimeter of my grow room "aluminized" from a previous grow, with the shiny part showing. I cut the grow room nearly in half(it was 12'x9', now a conservative 7'x7') by hanging a shower curtain from the beams in the ceiling, but I don't know if I should spraypaint it white, or cover it with mylar or foil. And would someone clarify if it is better to have the aluminum foil dull side showing or the obvious shiny side showing....
