Reflecting light - silver or white?

[Moggle]

Which would reflect light best - foil or some kind of glossy white? I'm trying to help out my little seedlings in the windowsills and mini-greenhouse, and was wondering which would reflect more light back on to the seedlings. At present I have a couple of inches of foil on the non-window side of the tray to help reflect light, but the toms especially seem to still lean towards the light. After reading in the HDRA encyclopedia about painting lean-to greenhouse walls white, it made me wonder if I laminated some white copier paper whether that would reflect more light?

I will probably do the experiment anyway, but would like to know what people here think too :)

I'd guess that foil would reflect more light -but that a white reflector would be more even and less likely to have 'hot spots'.

Look at mine in 'bucket potatoes'. It's the professional stuff. Foil faced plastic.

But our high intensity light reflector is white!
