Hanging Basket Watering Systems

A Labor Saving

Drip System

for Watering

Hanging Baskets
 Lower Input Costs Increases Profitability
Hanging Basket growers needing to reduce or eliminate
their hand watering labor costs can install a Netafim USA
SlimLine EZ Close™ system and expect a complete payback in
the first season from labor cost savings.
Only SlimLine EZ Close™ assemblies combine the benefits of:
• One-hand, EZ close shut-off of individual baskets -
prevents water and fertilizer spillage and waste.
• Snag-free slim design for easy retrieval from plants at
harvest – no more lost weights.
• 94% flow uniformity from the first basket to the last in
any system.

Actual Size
Cut Labor Costs
Typical labor costs for watering a hanging basket are about
$0.25 per basket each month. The Netafim solution for
hanging baskets will typically pay for itself in 100 to 120 days.
Use the following chart to analyze your payback.

Easy Shut-Off
This feature allows the dripper assembly to be closed easily
with one hand, preventing water and fertilizer from dripping
on the plants or walkways below. With a quick glance, it’s
easy to see if the assembly is open or closed.

 Cleaner, More Efficient Production
Higher Percentage of Top Quality Plants
When every plant gets precisely the same amount of water and fertilizer, exactly the amount you specify, the result is a more
uniform crop.
Netafim’s drippers feature both pressure compensation and a built-in check valve. This combination of features is the highest
level of technology available in drippers today. It ensures that every plant will receive precisely 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, resulting in a watering uniformity of 94%. The built-in check valve assures that all the drippers will turn on at the
same time (when the system is fully pressurized), and prevents the drainage of the system onto the lowest plants when the
system is turned off.

Multi-Tier Uniformity
Netafim Hanging Basket Drippers all flow precisely the
same, regardless of the length of tube (unlike old generation
drippers). This means that several lengths of drippers can be
combined on the same line, with each dripper providing the
same amount of water to both levels of baskets.

Prevent Algae Mess on Your Floor

Most old generation drippers soak the baskets to overflowing
at the beginning of the line by the time the baskets at the end
of the line receive adequate water. The result is both uneven
watering of the plants and often a major algae mess on the
floor from the overflowing baskets. One cause is the very high
flow of older generation drippers (often 20 times higher than
Netafim drippers). If the soil media dries a bit and shrinks
away from the wall of the basket, the high flow from the
old style drippers runs to the edge, into this gap and around
the soil, pouring out on the plants and floor below. Netafim Netafim - Old Generation -
Slow Flow High Flow
drippers flow slowly and uniformly, so the soil media is easily
wetted without any run-off around the edges of the basket.

Step Determine the dripper supply pipe sizing. Dripper

1 Using the top row of the WPCJ Dripper Supply Pipe

Sizing chart, select the dripper spacing to be used. By
Pipe

matching this to the length of the pipe column, the correct

size Dripper Supply Pipe can be determined.

Step Determine how many baskets can be watered

at the same time.
2 Use the Zone Flow chart to help calculate how much water it takes
to operate one zone of baskets. Select from the chart the number of
baskets to be watered at the same time. Use the flow that results
from this to determine the correct sizing for the pipe and control
head components. Each dripper has a flow rate of 0.5 gallons per
hour (GPH).

Step Select the distributor and mainline pipe sizes. Distributor and

3 Using the maximum flow demand from the largest zone or
combination of zones which may be watered at the same Pipe Size Maximum GPM*

time, you can size the Distributor and Mainline pipes from the ½" 6

Distributor and Mainline Pipe Sizing chart. Either PVC or ¾" 10

polyethylene pipe can be used for the Distributor and Mainline. 1" 17

If PVC is used above ground, it should be painted to prevent 1¼" 28

light penetration, which can result in growth of algae within 1½” 37
the pipe. This chart is appropriate for distributor lengths up to 2” 58
40 feet and mainlines up to 100 feet. When slopes are a factor, * Assumes class 160 PVC
when longer length pipes are needed, or for other special and 5 fps water velocity
conditions, please consult a certified Netafim System Designer
for assistance.

Step Select the major system components.

4 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. Make sure to size the pressure regulator by
determining both the minimum and the maximum number of
baskets which may be watered at the same time. Use a
35 psi Low Flow Pressure Regulator with zones of 400
baskets or less. 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 pipe sizes
and components (e.g. 1” filter on 1 ½” pipe) will have no
negative effect on the operation of the system if properly
sized by the flow demand.
