Netafim Dripper Stake Assemblies deliver superior uniformity with slow, low-flow drippers for even and uniform soil wetting without the run-off.
Growing In Soilless Cultures
The Netafim Dripper Stake Assembly is ideal for soilless substrates and hydroponic applications because each plant pot or rock wool cube receives an equal and precise amount of water nutrients.
Slow, Low-Flow Drippers
The slower and lower flow of Netafim drippers wet the soil media thoroughly without any run-off around the edges of the container. This allows longer runs on smaller polyethylene supply laterals maintaining excellent uniformity while holding down system costs. The PCNL dripper feature ensures that each plant receives the same amount of water at the same time. A built-in check valve assures that all the drippers will turn on - when the system is fully pressurized - and off at the same time.
High Value To Performance Ratio
Dripper Stake Assembly with PCNL dripper offers high performance for a very low cost per plant position.
Netafim Dripper Stake Assemblies can be used in almost any container operation. They are most commonly used with 3 to 15 gallon containers, although they operate effectively in both smaller and larger containers.
Higher Uniformity = Higher Crop Values
Most sprinkler systems lack uniform coverage and this creates wet and dry areas. Plant foliage interferes with water reaching the container. The result is a necessity to overwater many plants in order to provide adequate water to the dry areas and to overcome the interference of foliage. Netafim Dripper Stake Assemblies overcome these obstacles by delivering water directly to the plant. Each dripper adjusts itself automatically to the system pressure resulting in a watering uniformity of 94% - even on slopes. Since all water is delivered directly to the container, there is no run-off - no overspray into the aisles saving water, fertilizer, and energy.
Dripper Stake Assemblies Technical
Pressure Compensating Dripper
The WPCJ dripper is pressure compensating to provide a constant flow from 10 to 45 psi and has a built-in check valve to ensure instantaneous on-off at system shut-down. Drippers have a RED inlet for easy flow identification. No more straining to read the printing on the dripper - one quick glance and you can determine the dripper flow. Dripper Stake Assemblies are standard with 0.50 GPH* drippers. For higher flow rates, 1.0 and 2.0 GPH* drippers are available by special order. (* Nominal flow rate)
Angle Barbed Stake
The Angle Barbed Stake has a unique flow channel down the length of the stake directing the water into the container. It also has a pointed end for easy container insertion.
Super Flex UV White™ Polyethylene (PE) Tubing
This 5/3mm tubing Super Flex UV White™ PE Tubing produces cooler water temperatures and enhances plant growth. Made from the highest quality plastics with excellent Ultra-Violet (UV) resistance, our reflective white tubing is completely opaque to prevent algae growth. This tubing is not coated or layered white, it is solid white for long-term durability. It can withstand heat, direct sun and harsh chemicals.
Dripper Stake Assemblies Design Info
Using the top row of the DRIPPER SUPPLY PIPE SIZING chart to the right, select the dripper spacing to be used. By matching this to the length of pipe column, the correct size Dripper Supply Pipe can be determined. Typically the 0.50 GPH* dripper is used for most applications. Higher flow drippers are available for special applications, although for larger containers it is usually preferable to use multiple 0.50 GPH* drippers per container. As a general rule, use one 0.50 GPH* dripper for every 5 gallons of container size. The number of drippers that can be used on a single line is determined chiefly by the spacing and pipe size. If a high flow dripper, or slopes are involved, these must also be taken into consideration. (* Nominal flow rate)
Use the ZONE FLOW CHART below to determine the Flow Demand for the system. Select from the chart the number of containers to be watered at the same time. Use the resulting flow to determine the correct sizing for the pipe and control head components. Each dripper has a flow rate of 0.50 GPH*. (* Nominal flow rate)
Size the Distributor and Mainline Pipes using the Maximum Flow Demand from the largest zone or combination of zones which may be watered at the same time. Either PVC, or polyethylene pipe can be used for the Distributor and Mainline. If PVC is used above ground, it should be painted to prevent light penetration, which can result in the growth of algae within the pipe. Note: These charts are appropriate for distributor lengths of up to 40 ft. and mainlines of up to 100 ft. When slopes are a factor, when longer length pipes are needed, or for other special conditions, please contact Netafim USA Customer Service for further assistance.
Size the Head Control (filter, pressure regulator, and valve) based on the Flow Demand determined in Step 2. It is very important to recognize the minimum flow for the pressure regulator. Be sure to size the pressure regulator by determining both the minimum, and the maximum number of plants which may be watered at the same time. The size of the Head Control components should be determined by the flow demand, and not the size of the pipe that connects to them. Mixed sized pipes and components (e.g. 1" filter on 1 1/2" pipe) will have no negative effect on the operation of the system if properly sized by the flow control.
