Rainwater

Look at all that water exiting the rain gutter and flowing out to the street. Look at all those porch plants that could use that nice nitrogen-laden rainwater.

I stuffed a rag into the top of the rain gutter exit, used these huge red clamps to hold some tubing in place in the now-filling gutter and, voila, I'm filling a garbage can that I've put onto a skateboard (so I can move it to the next porch plant) and I have a second siphon tube from there to the plants.

A neighbor stopped his car to pause and stare at the ladder and the bright red clamps on the light gray house. He called a bit later to joke that he thought I was doing some sort of electrical experiment.

I'm just glad to be accepted by the hippies in California.
