Netafim PC (Pressure Compensating) Spray Stakes ensure every pot in the entire system receives exactly the same amount of water, from the first to the last. The spray pattern angles downward - just enough - to keep the spray on the soil and not flying into or over the wall of the pot. For simplicity, some growers place the spray stake near the edge of the pot, making the single-sided spray stake the best selection. Other growers prefer our unique 'bow-tie' double-spray pattern.
