The garden is inside a shade cloth structure so the birds are not an issue. The small tubing delivers a water and nutrient mix to a trough and the plants are suspended above the trough so their roots are submerged. The trough is sloped slightly so the nutrient mix flows down hill and what the plants don't take up runs out the other end and is collected and run through again. Many types of leafy vegetables are grown and the garden produces about 30 pounds a week.
