Here's a simple drip irrigation system that uses gravity to put rain water from a rain barrel exactly where it's needed in the vegetable garden. This dripper is designed for a square foot garden system, but can be used in any garden situation.
Drip irrigation is very efficient. Water is put exactly where it's needed-at the root system of the plants. No water is wasted due to runoff or evaporation.
This is my entry for the Get in the Garden contest. I hope you like it!
