Uniform Watering from the First Pot to the Last - Improves plant quality, simplifies design and controls system costs
Have you ever measured the difference in the amount of water the plants closest to the valve get compared to those furthest from the valve? It might be much more than you think and it adds up over time.
In a non-pressure compensating design, the spray stakes at the beginning of the line have a higher pressure and supply more water than those at the end of the line. Therefore, plants at the beginning of the line receive more water than they need by the time the plants at the end of the line are sufficiently watered. Each time the fi eld is watered these differences add up and eventually some plants can outgrow others, resulting in a lack of uniformity and less than a top-quality yield.
Netafim pressure compensating emitters have been in use for over 20 years and can now be used in spray stake systems. As a result, Netafim PC Spray Stakes ensure every pot in the entire system receives exactly the same amount of water. This eliminates the need to overwater some plants to be sure the driest plants receive enough water to thrive. This water savings is typically between 5% and 20% and can be even more.
