Hi, I have a long, narrow strip of dirt that I would like to water. Dimensions of strip is 2" x 20" (with some large plants interspersed). I have 1/2" copper running the length and I would like some recommendations on sprinkler heads. I am going for longevity here, so metal is the preference. The heads do not need a long reach (since the large plants will block the throw of water), but I need control over the angle the water is cast - so maybe 10 to 20 degrees spray on each side, 180 degrees apa...
