Sqwibb - nice setup! Far more elaborate than my simple 55-gal rain barrels. I do have two linked together for my main source and then a secondary barrel on the opposite side of the house. Even though they're up on blocks, gravity doesn't quite push enough water through a hose to water in-ground plants. Any supplemental watering done by hand but all of my potted plants get rain water instead of city water. Saw on another thread that you also do "chop and drop". One of the easiest concepts to adopt. I am selective though - no undesirable seed-bearing plants and I try to pull out weeds first. Good for our MW winters when snow isn't always on the ground. And hopefully plant nutrients get back into the soil.
