We found 1 gallon plastic buckets, the same style as 5 gallon buckets, at the dollar store. They make good planters with holes drilled in the bottom. The ones we found were black, so they'll hold heat, and perhaps not be the best for some items in a hot climate. If you get creative about planting containers, the dollar store has all sorts of options.
