Rubbermaids rule :The Earth Tainer. How to build your own self watering container, similar to the Earthbox. I made something similar called a Global Bucket (see the Pin in my Garden Board on them) to grow tomatoes and made a box like this one for my Basil. The Basil was amazing. I'd water it once in the morning and it always used just the amount of water the plants needed. Build one this year. You won't be disappointed with the results.
