Pressure Compensating Spray Stakes
Netafim PC Spray Stakes are pressure compensating with a check valve for improved control of water and fertilizers. The efficient spray pattern wets the soil surface to maximize water retention while misting is nearly eliminated and wind drift is prevented. The simple construction, easy close-off mechanism, and resistance to sunlight, fertilizers and chemicals means long-life reliability.
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.
SIMPLE, SECURE SHUT-OFF
The side-mounted, secure shut-off is easy and fool proof. For close off, remove the nipple and tubing from the top of the spray stake and attach it to the side of the spray stake. This provides a clear, visual indication – even from a distance – if a unit is in the on or off position.
EFFICIENT SPRAY PATTERNS
Pick the spray pattern that is right for your plants. The single spray pattern spray stake can be placed near the edge of the pot. The double spray pattern spray stake is useful for optimized wetting in very coarse mixes or large pots. It also allows positioning of the spray stake near the stem of the plant which can minimize wetting of the base of the stem.
ADAPTABLE TO ALL SOIL MEDIA TYPES
Stake or rod mount options allow more application options and greater flexibility. The rod mount spray stake is ideal for deeper insertion into coarse bark mix for added stability and greater allowance for height adjustment to increase the size of the wetted pattern.
