Best value: 1/2 GPH emitters at $92.401/2 GPH emitters deliver water slowly, ideal for clay soils and small plants. Total flow: 52.0 GPH.

Consider zone splitting for large systemsWith 104 emitters, you may benefit from dividing the system into 2+ zones with a timer. This ensures consistent pressure and even water distribution across all rows.

This is an estimate for planning purposes. Actual component needs may vary based on water pressure, elevation changes, and specific fitting requirements. Always consult with an irrigation supplier for your specific layout.
