Netafim Drippers, Emitters & Sprayers
This collection covers Netafim's emitter and sprayer product lines -- the components that deliver water and nutrient solution at each individual plant site in a drip or micro-irrigation system. Netafim produces pressure-compensating drip stakes, inline drip emitters, micro-sprayers, and sprinkler heads used across commercial greenhouse, nursery, field, and indoor hydroponic applications.

Woodpecker Pressure-Compensating Drip Stakes
Netafim Woodpecker drip stakes are the most widely used commercial drip emitter in North American indoor growing. The Woodpecker design is self-piercing -- the stake body punches directly through poly tubing without a separate barb insert, eliminating a fitting connection point and reducing installation time in multi-plant drip systems. Their pressure-compensating mechanism delivers a consistent GPH output (0.5, 1.0, or 2.0 GPH depending on model) across a wide operating pressure range (10-50 PSI), ensuring every plant site on the irrigation run receives identical flow regardless of its distance from the pump. This pressure compensation is the critical feature that makes Woodpecker stakes the professional standard for any drip system with more than 10-15 plant sites on a single run. For the 17mm poly tubing, TechLock fittings, and disc filters needed for a complete Netafim drip system, see the main Netafim irrigation collection. Expert support available.
Netafim Micro-Sprayers & Sprinklers
For applications where area coverage rather than point-delivery is needed -- nursery production, seedling irrigation, overhead misting, and open-bed horticulture -- Netafim produces micro-sprayer and sprinkler heads in a range of coverage patterns and flow rates. Micro-sprayers connect to 1/4-inch or 5/32-inch micro-tubing via standard barb inserts and deliver a fine spray pattern suited to seedling trays, rooted cuttings, and overhead misting of growing media.

Netafim Drippers & Emitters FAQ
What makes Netafim Woodpecker drip stakes different?
Three features distinguish Woodpecker stakes: self-piercing installation (no separate barb fitting needed), pressure compensation (consistent 0.5-2.0 GPH across 10-50 PSI operating pressure), and long-term clog resistance through their internal flow path design. The pressure-compensating mechanism is the most operationally significant feature -- it ensures every plant site on a drip run receives identical water and nutrient delivery regardless of its position relative to the pump, eliminating the head-to-tail flow variation that non-PC emitters produce over long irrigation runs.
What GPH Woodpecker drip stake should I use?
Match GPH to your irrigation frequency and container size. For high-frequency irrigation programs (6-12+ events per day at low volume per event, typical in commercial coco grows): 0.5 GPH stakes deliver adequate volume per event at short cycle times. For lower-frequency programs (1-3 events per day at higher volume): 1.0 or 2.0 GPH stakes deliver more volume per event and work better with longer open times. When in doubt, 1.0 GPH is the most versatile for hobby and mid-scale commercial grows. Two 0.5 GPH stakes per container provides the same total volume as one 1.0 GPH stake with better spatial distribution across the container surface.
