Please note that you may get brown or green emitters -- they are both 4 Gph.
Where water delivery to an individual plant is needed. Emitters attach to .5" or 1/4" poly to deliver water to landscape or garden. These Flag emitters are flushable and easy to clean out by removing the flag end. Install pointed end into water supply. The end where the water comes out can either be placed onto the ground (not stuck into the ground), or installed next to the plant with the help of a Short Stake. (Ship wt 0.005 lb)
The stream of water was a little too forceful for the intended application of these emitters. I had them in pots of herbs in my garden. In a better location, I think they'd be great!Review by Katie (on 12/27/12)
