We have toyed with the idea of trash can rain barrels for the downspouts and trash can passive heat absorbers for the (future) green house and even trash can composters (which didn't really work very well but that is another story for another day). Enter mobile trash can orchard waterer, courtesy of my husband's ingenuity. Lid on, no splashing, gravity fed, large capacity, inexpensive to make. I had been coveting all sorts of containers to purchase for this purpose. Hubby made this out of things we already had. Free and effective; gotta love that.
