Last year we had a hard time keeping the garden watered. It was just to hot and didn't rain regularly. We watered with the garden hose but the electric pump was running almost constantly. There is also some question as to how good the pumped water is since the house was moved over to municipal for drinking and bathing long before we bought it. So I was thinking that I could rig up some kind of rain cistern with a slow drip watering hose to the garden. My thoughts are to install a wooden gutter that dumps the water into a large rain barrel which is attached to a gravity fed hose with tiny holes punched through at the base of each plant. I would have the hose valved and open it each day beore heading off to work. Have any of you tried this before? Pros? Cons? Advice and comments appreciated.
