The Emitters come in a variety of flow rates to suit different plant needs and watering preferences. Among the NPC (Non-Pressure Compensating) Emitters, the Yellow variant releases water at a rate of 2 liters per hour (LPH), ideal for plants with low water requirements. The Green emitter disperses water at 4 LPH, offering moderate hydration suitable for various plant types. For plants with higher water needs, the Black NPC Emitter provides a flow rate of 8 LPH, while the Blue NPC Emitter, with a flow rate of 14 LPH, caters to plants requiring frequent watering or in areas with high evaporation rates. Additionally, the Black PC (Pressure Compensating) Emitter offers controlled watering at 4 LPH, ensuring precise distribution for optimal plant growth and water efficiency.
