I tried red plastic mulch in 2007. Once the plants are big you can hardly see the plastic, unless you have a really big piece of it, such as covering the whole bed. Doesn't look too great either. I'm guessing this is another one of those things that works in theory and at a research station, but is not all that practical for the real world.
Just my opinion, but I won't try it again.

BTW Ray, I think there is a web site still floating around out there somewhere that gives a detailed scientific angle on it. I think that's where I got the idea, but after my own test, I saw no practical value to it.
