gardennut,

The basic principle of an Earthbox-like system is to have a water reservoir wicking action to self water the plants as they need it. Not sure how you would accomplish this with a brick and mortar design. The 31 gallon Rubbermaids make an excellent 2 plant solution, they are movable, and are not "permanent" (future home owner may not appreciate the thing).

This is what I have built (26 EarthTainers).

Not a bad idea if you are certain that you will want to keep it there. What happens if you decide that it does not work like you thought it would? Now you have 1000# of bricks to get rid of.

But if you decide to do it, you will definately need some kind of liner to keep the water from coming through the brick and mortar. Maybe you can contact a pool store to find out if they have any pool liners that were damaged while being installed. I'd think that they would hold up a bit better than plastic sheeting.

You'd also need to make sure you have enough wicking chambers to get enough water into the soil. Please post your findings so we can all learn from your experiences. Good luck with it.
