This device gives you the option to "set it and forget it" for a whole week, including when you want to keep in mind the weather (if rain is called for on Tuesday and Wednesday, you can program it to not run on those days and let Mother Nature do the watering). And it also gives you the freedom to not have to get up in the middle of the night--or very early in the morning--to water at the most efficient time of the day during a hot summer. The dual hoses allow you to water multiple gardens in different directions. We could see this set up with a drip hose for even more efficient watering.
Do you have any garden tools (besides the expected ones) that you rely on?
