pressurised drip irrigation

measured irrigation with
Dot2dot porous hose

measured irrigation with
dripper nozzles

inadequate control of the volume of water delivered to each plant

directly controls the volume of water delivered to each sector

directly controls the volume of water delivered to each sector, and the volume of water delivered to each plant within the sector

blocked drippers can be a problem

no drippers to get blocked

blocked dripper nozzles can be a problem

a high level of filtering is required to prevent small particles blocking the drippers

filtering is required to prevent nozzle blockage at the flow splitter (Dot2dot hose does not get blocked)

filtering is required to prevent particles blocking the dripper nozzles

identifying and clearing blocked drippers is tedious and time consuming

identifying and clearing blocked  flow-splitter nozzles is quick and easy

identifying and clearing blocked dripper nozzles is easy
