Metal,

Opie is right.....flat white reflects more evenly. In my last grow log on page one if you read you'll see what the results were from the my painting the walls flat white and why.

Thanks for the comments folks. I appreciate everyone stopping by.

Opie....I know I'm being a noid.....but when you ARE being a noid you never THINK you're being a noid.
