Tomato Box Watering System

A five gallon bucket with a sealed lid with a filler cap and hoses out of the top and bottom of the side. One hose goes to the bottom of the tomato box to feed the water, the other goes down the fill pipe and controls the amount of air returning to the bucket. When the water in the bottom of the tomato box drops below the hole in the side of the hose down the filler pipe, air goes into the bucket allowing water to go into the box until the level rises and stops the air from going into the bucket.
