This is my half inch PVC raised bed irrigation system. Very easy to make I show the parts necessary To build it. You need to drill a row or 2 of 1/16th inch diameter holes on the bottom edge of the pipe leave the pipe uncemented to the manifold so you can turn it where it is needed. I also share this compared to my Mr. Irrigation system I have installed I like the PVC set up much better. This should free up 14 + hours a week of my time.
