I recently visited an urban farm and was intrigued with their irrigation system. I haven't been able to find the components online either because they built it from scratch or I'm using the wrong terms. Unfortunately I didn't take a picture of the set up.
The main line is pvc pipe with holes rather than polyethylene pipe and it had 1/4" tubes coming from the pvc directly to each individual pot. Water drips out in drops rather than as a stream.
Anyone has an idea what this system is called or where to get the components?
