Here's my Earthbox as pictured on the 21st February 2016. As you can see the vegetables have been growing well. I haven't had to water this container since I set it up, I haven't carried out any maintenance of any kind, I just left the vegetables to grow. I have harvested some of the stems and leaves from the chard, but other than that, the vegetables have been left to grow.
