You need an "emmiter" at the end of the drip lines.

BTW, you can put a globe valve after the regulator to drop the pressure
and adjust the flow rate without having to change the regulator. A small
gate valve also works well, even thought the valve says to only operate
fully-open or fully-closed.

sorry, should have said - the dripline has pressure compensating emitters
every 12 inches.
