Flat white - acrylic is fine -

Some of the better grow rooms are decked out by hanging a white mylar which I think they say Walmart carries.

Walmart also sells something called an "emergency blanket" in their camping / hunting department. It's made of stuff that looks silvery like tin foil... and some have used that

Always Go With Flat White.
