Netafim Woodpecker Pressure Compensating Junior Dripper with CNL - 0.5 GPH - Red - 13000 Count

Even 0.5 GPH Watering With Less Drain-Down - Red Dripper

Uneven watering across a drip line wastes water and nutrient solution and leaves some containers drier than others. The Netafim Woodpecker Pressure Compensating Junior Dripper holds its output steady as line pressure changes, and its CNL (Check Non-Leak) valve limits dripping between irrigation cycles. That keeps each container on a consistent schedule.

This listing is for the 0.5 GPH red version. It suits growers who want a moderate, repeatable flow per container in indoor rooms, greenhouses or larger hydroponic builds, and who want to match emitter output to plant water demand.

Key Features & Benefits

• Pressure compensating output — delivers consistent flow across a range of line pressures, so emitters at the start and end of a run behave alike.
• CNL (Check Non-Leak) valve — limits low-head drainage between cycles, helping keep media moisture steady.
• 0.5 GPH flow rate — gives a predictable per-emitter output for scheduling irrigation.
• Junior dripper format — a compact emitter suited to container drip lines.

Who Should Use Netafim Woodpecker PC Junior Dripper with CNL

Commercial and home growers running container or substrate drip irrigation, especially on lines with elevation changes or long runs where pressure varies. It also suits anyone replacing worn emitters and wanting to keep the same flow rate.

Frequently Asked Questions

Q: What does CNL mean?
A: CNL stands for Check Non-Leak. The valve closes when the line pressure drops, so water does not drain out of the tubing through the emitter between irrigation cycles.

Q: What does pressure compensating mean?
A: A pressure compensating dripper keeps its flow rate steady as line pressure changes. This helps emitters along a long run or on uneven ground deliver similar amounts of water.

Q: What pressure range does it operate in?
A: It operates between 7 and 45 PSI. Keep your system within that range for consistent output.

Q: Is this a good choice for sloped or uneven setups?
A: Yes. Pressure compensation evens out flow across elevation changes, and the CNL valve reduces drainage from the lower emitters after the pump stops.

Q: Are other flow rates available?
A: Yes. The Woodpecker Junior line also comes in 0.32, 1.0 and 2.0 GPH versions. This listing is the 0.5 GPH red version.

Q: How is this listing sold?
A: It is sold each. Check the quantity in the product name before ordering so it fits your system build.
