Netafim Pressure Compensating Standard Spray Stake Double Pattern - 6.6 GPH (Grey) 50 Units Per Order 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. Pair the 3.2 GPH spray stakes with the Netafim 36 in (40201-002020) or 48 in (40201-024700) single spray stake assembly and the 6.6 GPH spray stakes with the Netafim 36 in (40201-002320) or 48 in (40201-024800) single spray stake assembly. SUPERIOR WETTING OF THE SOIL MIX The PC Spray Stake pattern angles downward – just enough – to keep the spray on the soil and not flying into or over the wall of the pot. Water retained by the soil mix is the most important measure of the effectiveness of a spray stake. The Netafim spray pattern provides maximum water retention by the soil mix – exactly what the plant needs. An additional benefit of the excellent wetting pattern is the uniform activation of top-dressed fertilizers. The result is superior plant growth and more efficient use of water resources. UNIFORM WATERING FROM THE FIRST TO LAST POT Pressure compensating 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 55% to 20% and can be even more. ELIMINATES MISTING Non-compensating spray stakes produce a lot of mist that is wastefully blown away especially on a windy day. One more advantage of pressure compensation is that it conserves water. Even at high pressures, up to 60 psi, the pressure compensating mechanism and the downward water spray of the Netafim PC Spray Stake eliminate misting.
