Last year I tried running a drip irrigation system on my hops. I continually blew the cap off the end due to the pressure. This year I wanted to install something a little hardier to water my hop yard. My pastor is moving away and had a lot of 1" PVC pipe he was getting rid of and I was able to get nearly 30' of it. My original design was to just run 40' and drill 1/16" holes in front of the hops and leave it above ground. The UV light from the sun would eventually degrade the PVC, but the frost would burst it if there was any water in the line once Winter came.
