One blue barrel is hooked up to the rain spout which will funnel rain water in.
Both barrels are full of water.
The barrels are linked together with tubing which is also linked to the Garden Anywhere Boxes.
If it is dry for a while and we run out of rain water, the outside faucet will automatically kick into gear and water the plants.
This is a box of kale that you see.
Notice the dog dish!
With this watering system, even the dog is not forgotten. Fresh water everytime they drink.
