The Netafim Spray Stake pattern is specifically designed to match the shape of the pot and provide a precise amount of water and fertilizer directly to the plant. The pattern wets the soil surface evenly to maximize water retention by the soil mix and evenly release liquid or timed-release fertilizers. Overspray or water run-off is eliminated saving water, energy and fertilizer costs.

SUPERIOR SOIL WETTING = IMPROVED PLANT QUALITY

Netafim Spray Stakes were built from the beginning to fill the needs of the nursery grower. 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. Water flying out of the pot is wasted, while water that hits the side of the pot typically runs down and out the bottom and is not effective in wetting the soil mix. The Netafim spray pattern provides maximum water retention by the soil mix – exactly what the plant needs. The result is superior plant growth and more efficient use of water resources and fertilizers.

RUGGED AND RELIABLE ONE-PIECE CONSTRUCTION

The simple one-piece construction provides reliable long life performance with over 15 years of proven field experience. They are highly resistant to sunlight, fertilizers and chemicals. Installation is very simple and the Netafim micro-tubing fits securely to the top of the spray stake.

SUPER SIMPLE TO CLEAN

Tough water? Netafim Spray Stakes are made for real-world field conditions. If blockage occurs, simply remove the spray stake from the micro-tubing, rinse the flow channel and reconnect the spray stake and micro-tubing. The spray stake can be restored to operation by any level of field worker in a matter of seconds.

SIMPLE CLOSE-OFF FEATURE

The close-off nipple, located on the side of the spray stake, eliminates dirt from entering the tube, a common occurrence with tip-mounted close-ff nipples. It also gives a simple, highly visible cue that the stake is closed, not open.

SPRAY DIRECTION INDICATOR SAVES TIME AND LABOR

Each spray stake has a built-in spray direction indicator on one side of the stake. Quickly see or feel the spray direction to speed and simplify installation without having to return and make adjustments.


STEP 1 - DETERMINE FLOW RATE

Most growers start by selecting the flow rate for their spray stake. See the Product Selection Guide chart for some general recommendations. The flow rates listed in this chart are 'Nominal Flow Rates" and will vary depending on system pressure. Remember, these are not strict limitations, just general guidelines. Many growers with larger pots use higher flow spray stakes, while others prefer to use lower flow spray stakes and simply operate them longer. The next consideration is how long a row or “run” of pots you want to water. Lower flow spray stakes can water longer runs than higher flow spray stakes. The Pipe Sizing and Maximum Row Length chart will help ensure your spray stake selection fits your design - this will be covered in a later step.

STEP 2 - DETERMINE SPRAY STAKE SPACING

After selecting the flow rate for the spray stakes in Step 1, the spray stake spacing needs to be determined. Normally this is the spacing between the pots. If your pots are spaced at 48” and you are using one spray stake per pot, your spray stake spacing is 48”. If you are using more than one spray stake per pot, then the spray stake spacing is the average spacing between spray stakes. For example, if you had pots spaced 48” apart and are using two spray stakes per pot, the average distance between spray stakes is 48” ÷ 2 = 24”.

STEP 3 - DETERMINE SUPPLY PIPE SIZING

The Pipe Sizing and Maximum Row Length chart will help you select the pipe sizing appropriate for your design. Larger pipes allow for longer runs and this chart will help you pick the right size pipe. The chart lists both the maximum run length in feet and the number of pots (shown in parenthesis). Using the Spray Stake color (flow rate) you selected in Step 1 and the spacing you determined in Step 2, read across the Pipe Sizing and Maximum Row Length chart until you find the length which is greater than your row length. Refer to the column heading above this number for the pipe size to use.

Note: This chart is intended for designs on flat ground. For sloping ground, use a qualified Netafim dealer to assist you with your design.

STEP 4 - ZONE SIZING BASED ON AVAILABLE FLOW RATE

Multiply the number of spray stakes you have in each row by the number of rows you will be watering at the same time. This is the total number of spray stakes you want to operate at the same time - a watering “zone”. The Zone Flow chart will convert that number of spray stakes into gallons per minute (GPM). This zone flow will be helpful in determining the sizing for mainline pipes and other system components.

STEP 5 - SIZING THE SYSTEM COMPONENTS

Recommendations for sizing basic versions of valves, filters, water meters and pressure regulators for your zone flow can be found in these charts. Detailed additional information for performance and specifications can be found on the technical sheets for each component. These are available on our website at www.netafimusa.com, by calling Customer Service at 888-NETAFIM or through our network of qualified dealers.

Note: Sizing the mainline pipes should be done through a certified irrigation designer.
