I added three rows outside the high tunnel and wanted to connect them to my drip system. It's about eight feet from the end of one row to the start of another. If I irrigate that ground, it wastes water and makes the weeds grow too fast. So I bridged the gap with a piece of 1/2" pvc pipe. There's a drip tape fitting that is Tape Lock to PVC. I also plumbed a valve in it.
I buried the pipe after I took the pic. As long as the sun stays off of it, the pvc should last nearly forever.
