Am I right in thinking tin foil is a bad idea for reflecting light onto plants?
If so, why is this?

Yeah man, dont even try it. I was ignorant and tried it anyway one time and it didnt do nothing good. Im with lars, white paint!!! Luckily my walls were already white. haha. But reflection aint no big deal anyway.
I've heard this question argued back and forth, many times! Has anyone, ever, actually had damage done to thier plants from these. so called, "hot-spots" caused by wrinkled aluminum foil? I think it's just a myth started years ago, that everybody passes on!
The real reason not to use aluminum foil, is because it has a relatively low "Reflective Index". It looks nice and shiny - it just doesn't work that well. Flat white paint works better - Mylar is better still!
I find it hard to believe that a third rate (at best) reflective surface, with random wrinkles, would be able to focus and concentrate the light energy, to the point where it becomes toxic! And the same goes for "Radiant Heat". It just doesn't make sense to me! Is there some basis in reality to this "No-no"?
I have used foil, as a temporary reflector, in the past, with no ill effects - it worked for me.

I used it for a while and i strange brown colors on my leifs. But then again i had it about 4 inches away from my plant. It does reflect light and it does cause problems. Anyone can feel free to try it but it might cook your plant.

ok, so I've now got my box set up with dull side of tin foil. Not too close to plants so I can't see it causing problems.

I have a 400W HPS system for when the plants get a bit bigger/more robust.
I wont be using tin foil when this goes on, might have to invest in some mylar.

Its not the hot spots. Foil generates heat in area, so if you in a little box it will add to your heat problems.
