Watering system

I'm experimenting with a new watering system this year. I've got myself some clay pots and stopped up the hole in the bottom.

Then I fill the pot with water and the water slowly seeps out.

Like this.

The idea is that you bury the pot next to a plant and put a cover over the pot. Then the plants roots grow around the pot and it grows.

This is based on the idea of the ollas which were used in the Southwest. I would like to purchase a few ollas, but they are $25-$30 apiece. Too rich for my blood.
