Two 35-gallon rain barrels, constructed in tandem. We make our own & run our drip irrigation to the rose beds from these. Very, very convenient and the savings on our water bill are incredible.
Home-made rain barrels, with rain chain. Ditched the gutter on the side of the house & went to this setup, as we previously had far too much precip running off the house & into our yard, and our neighbors' yards. This is the best idea we've had in years.
