My wife and I are planning a small kitchen in our yard where we can grow a few tomatoes and other vegetables next year. We wanted to build in some self-watering pots so we wouldn't have to worry about the vegetables if we went on a short trip. She found the plans to this planter through TomatoFest and after looking over the diagrams and watching the video's I was impressed. Ray Newstead, the inventor of the system, put a lot of thought into the construction, including that every part is easily available to the average person. You can get everything you need at Lowes. (Buckminster Fuller would be proud!)
The plans are freely available for download. Ray only asks that you make a donation to Feed The Children organization. It's a little late in the season to be planting tomatoes here in Colorado and I don't quite have the area ready for the planter but I want to get a head start on next year. If I get one built, I'll post the results.
