Potted Plant Watering SystemsN E T A F I M U S AA Labor Saving Drip Systemfor Watering Potted Plants2Production ToolComparing a Netafim system to hand watering is like comparing a hand saw to a power saw. A hand tool is fine if you have the time, but for production scale growing, power tools are a terrific step forward.Higher Crop ValueThis results from having a highly uniform top quality crop - which is what to expect when water and fertilizer uniformity are improved. Netafim’s Multi Outlet Drippers (MOD) feature both pressure compensation and a built-in check valve. This combination of features (referred to as PCNL) is the highest level of technology available in drippers today. This technology ensures that every plant will receive exactly the same amount of water and fertilizer regardless of where the plant is located within the system. Each dripper adjusts itself automatically to the system pressure and elevation so that even on rolling or sloped ground, the uniformity of watering is 94%. The built-in check valve prevents unwanted drainage of the system onto the lowest plants when the watering cycle is completed.Less DiseaseWater on foliage and flowers can spread disease rapidly. By applying water directly to the pot, the rest of the plant remains dry. Additionally, pesticides which are applied to the foliage are not washed off by daily watering. This can reduce the need for spraying, further lowering production costs and decreasing run-off.4-Way MOD System8-Way MOD SystemAngle Arrow DripperA Low Cost Potted Plant Watering System That Saves Labor3Low Cost and Fast PaybackPayback for a complete system is usually within the first season of operation.Manifold VersatilityWhen many small pots are to be watered, two manifold assemblies can be stacked together to create an 8-Way assembly. The flow per pot is then 0.25 gallons per hour (GPH). For every 10 gallons per minute (GPM) available, 2,000 pots can be watered.

The dripper supply tubing (with the dripper attached) can then be rolled up without tangling the spaghetti tubes. If a different plant spacing is desired, simply change the manifold.Multi-Outlet Drippers Improve Plant Quality4Pressure Compensating DrippersThe WPCJL is pressure compensating to provide a constant flow from 10 to 45 psi and has a built-in check valve to prevent system drainage into the lowest plants. • Flat 4-Way manifold is usually combined with the 2.0 GPH WPCJL Dripper - 0.50 GPH per plant. • Flat 2-Way Stackable manifold is usually combined with the 1.0 GPH WPCJL Dripper - 0.50 GPH per plant.Three Manifold OptionsThe flat manifold is ideal for field applications. The low-profile design and durable construction resists damage from field workers. The Flat 2-Way or 4-Way Stackable manifold is combined with a 2-Way or 4-Way manifold to create additional configurations.Flat 4-WayManifoldFlat 2-Way Stackable ManifoldFlat 4-Way StackableManifoldUV White™ PE TubingFully UV resistant and completely opaque to prevent algae growth. This tubing is not coated or layered white; it is solid white for long-term durability. Netafim’s UV White™ PE Tubing produces cooler water temperatures and enhances plant growth.Angle Arrow DrippersTwo Angle Arrow Dripper options are available:• The standard Angle Arrow Dripper is 6 3/8” in length and is used for large pots.• The Short Angle Arrow Dripper is 3 3/4” in length and is ideal for 4” to 5” pots.Shown actual size.Multi-Outlet Dripper Components5Dripper Spacing Dripper Supply Pipe Distributor Pipe Mainline Control Head Use the Zone Flow Chart below to determine the Flow Demand for the system. Select from the chart the number of plants to be watered at the same time. Use the resulting flow from this to determine the correct sizing for the pipe and control head components. Note that the 4-Way MOD has a flow of 0.50 gallons per hour (GPH) per plant, and the 8-Way MOD has a flow of 0.25 GPH per plant.Using the top row of the table at 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.4-Way MOD Dripper Supply Pipe Sizing Assumes 35 psi inlet pressure, 10 psi at lastdripper and no slope.Length of Pipe (feet) Dripper Spacing (inches) 36"16mmpoly24"16mmpoly18"16mmpoly6"16mmpoly12"16mmpoly50 100 150 200 250 300 350 400 1/2"1/2"poly3/4" poly 1" poly 3/4" poly 1" poly 1/2"poly3/4" poly 1/2"poly3/4" poly 1/2"polyStep1Step2Zone Flow Chart (GPM) Assumes use of a 2.0 GPH dripper.Number of Plants 2000178180015816001371400126120010510008440032200218007360053GPM 4-Way MODGPM 8-Way MODDesign Help for Multi-Outlet Dripper Watering Systems6FLOWSize 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. These charts are appropriate for distributor lengths up to 40 feet and mainlines up to 100 feet. When slopes are a factor, when longer length pipes are needed, or for other special conditions, please consult a certified Netafim System Designer for assistance.Size the Control Head (valve, filter and pressure regulator) 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. Use a 35 psi Low Flow Pressure Regulator with zones of 400 pots or less and 4-Way MODs. The size of the Control Head components should be determined by the flow demand, and not the size of the pipe that connects to them. Mixed size 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 demand.Distributor andMainline Pipe Sizing 1/2” 6 3/4” 10 1” 17 1 1/4” 28 1 1/2” 37 2” 58Pipe Size Maximum GPM** Assumes class 160 PVC and 5 fps water velocity.Step3Step4Valve, Filter and Pressure Regulator SizingFlow Range (GPM) Unit Size ItemNumberElectricValve(24VAC)PressureRegulator(35 psi)Disc Filter (120 mesh) .01 - 26 3/4” Globe 71640-007355 61ET.75-GH2 .01 - 44 1” Globe 71640-007406 61ET1GH2 .25 - 110 1 1/2” Globe 71640-007425 61ET1.5GH2 .25 - 176 2 Globe 71640-007660 61ET2GH2 1 - 12 3/4” 70640-001200 25A45-120 1 - 26 1” 70641-001600 25A47-120 1 - 52 1 1/2” Super 70641-003420 25A17-120 1 - 110 2” Dual Lite 70640-004521 25A2DL-120 .25 to 4.4 3/4” Low Flow 31000-001200 32PRV.75-LF35V2 4.5 to 17.6 3/4” 30500-001600 32PRV.75-35V2K 11 to 35 1 1/2” 30520-001600 32PRV1.5-35V2K 22 to 70 2” (x4) 30540-002700 32PRV2-435V2KModelNumberValve PressureRegulatorFilterControl Head Assembly Order:1.
