Photo below - here's a roma tomato plant, that is not in a swc. I know it looks like one, but the bottom bucket is only used to catch the water that drains from the top one. It'll probably be converted next year, though.
Photo below - the other paste tomatoes, and jalapeno peppers. The siphon is still intact, and the rain has been keeping the supply bucket to a good level, too. The opalka plants are much bigger than the romas in the back. Boy...I hope they do well, because homemade spaghetti sauce would be nice this year!
