I was at Menards for a few minutes and I ran across this white tray that is about 3' x 3' and about 3.5" high. It is supposed to be used under washing machines just in case there is a leak. I took a look at it and thought hmmmm, think I'll buy this as I'll be able to set it out on the patio and place many pots in it this summer. Nice size and the perfect height to be able to water plants from the bottom up. It was white though. No other colors were available. Price was $13.
