The Aquifer is simply the best irrigation solution, that I have found, for small scale farms and gardens. Since it is made of poly and brass it will last a very long time and there is no rust to clog the sprinkler. The slim design means that it doesn't get in the way when walking or cultivating in the paths.
Sold without the sprinkler head. Can be used with any sprinkler with a 1/2 inch fitting.
