Raindrip Watering Vegetable Garden Kit #R562DT: Home Improvement
This Raindrip system is great for limiting water use in the garden which, besides saving water, cuts down on weeds. I've used a system like this for years with very little maintenance. You can also make it "automatic" by tying it into a sprinkler system or other water source that is used regularly.
Grow your own vegetables. Not only will you cut down on costs but you'll decrease all the emissions related to food travel costs.
