For the other zones I use 'Shrubblers'. They can be dialed to give 0-10 gpm per head. On these zones using the shrubblers you should not use a pressure regulator. I measured about 60 psi coming out of the hose bib. I have been able to put 50+ shrubbler on each zone. There is no pressure drop on the heads and I believe I could double the amount of heads if need be. The larger pots I like to run two heads as insurance in case a head decides to clog. This has worked wonderfully so far this year
