Micro Irrigation for cinderblock beds
I've been in the process of setting up a micro irrigation system for my garden. I have cinderblock raised beds, with additional plants in the cinderblock holes on the border of the bed.
All the main plants in the regular beds have a drip emitter. I was wondering what the best way to water the plants in the cinderblock holes. Should I do a drip emiter for each plant or set up a sprinkler that might cover more than one hole?
Also, I had a barbed 1/4" connector break off and a part fell into the 1/2" mainline hose. Is this piece going to cause issues? I don't know how to get it out without cutting the hose.
