Netafim .5 GPH Single Drip Stake Assembly – 36 in (25/Bundle)

The Netafim .5 GPH Single Drip Stake Assembly (36-inch, 25-bundle) is a pre-built drip irrigation component designed for hydroponic, coco, and container growing systems. Each assembly pairs a 0.5 GPH pressure-compensating emitter with a CNL check valve, 36 inches of Super Flex tubing, and an angled barbed stake — everything you need to deliver water directly to the root zone, sold as a ready-to-install bundle of 25.

Netafim .5 GPH Drip Stake Assembly Specifications

Specifications below are derived from the canonical product listing for SKU 40201-021000. Flow rate and pressure requirements are fixed by the emitter design; tube length and stake geometry are specific to the 36-inch variant.

Why Choose the Netafim .5 GPH Drip Stake Assembly

Netafim’s drip stake assemblies are designed to cut installation time by combining all the components of a single-plant drip point into one pre-assembled unit. Rather than cutting tubing, inserting emitters, and positioning stakes separately, you connect the barbed inlet to your mainline and push the stake into the growing medium — done. Here is what distinguishes this assembly:

• Pressure-compensating emitter: The 0.5 GPH emitter maintains a consistent output across a range of line pressures above the 10 PSI minimum. This matters in systems with multiple drip points on a single supply line where pressure varies from the first emitter to the last.
• CNL check valve: The built-in CNL (check-non-leakage) check valve prevents water from draining out of the tubing when the pump shuts off. This keeps the line primed between irrigation cycles and avoids pooling at the base of pots between scheduled waterings.
• Super Flex tubing: The 36-inch length gives you enough reach to route from a mainline running along the edge of a bench to the center of a container. The Super Flex material does not kink under normal routing and holds its shape once positioned.
• Angled barbed stake: The stake is designed to sit at an angle in the growing medium, directing water toward the root zone rather than straight down the side of the pot. The barbed profile keeps it in place after initial insertion.
• Bundle of 25: Sold as a 25-unit bundle, this assembly is suited for growers expanding a drip system across multiple containers or replacing emitters at scale without purchasing individual components separately.

Best Uses for the Netafim .5 GPH Drip Stake Assembly

This assembly fits most drip irrigation setups where plants are grown individually in containers and each plant needs its own drip point. The 0.5 GPH flow rate and 36-inch tubing length make it practical across the following applications:

• Recirculating drip systems: In a recirculating setup, the pressure-compensating emitter and CNL check valve work together to deliver uniform volumes per cycle and prevent nutrient solution from siphoning back into the supply line when the pump stops.
• Run-to-waste drip irrigation: For run-to-waste setups in coco coir or perlite, the 0.5 GPH rate supports frequent short irrigation cycles without oversaturation in typical container sizes used in indoor cultivation.
• Multi-plant bench arrays: When running 10–25 plants on a single supply line, the pressure-compensating design ensures each plant receives the same volume per cycle regardless of its position on the line.
• Rockwool or coco cube top-feed: The angled stake can be positioned to direct flow onto the surface of a rockwool slab or coco cube where top-feeding is part of the propagation or early-vegetative protocol.
• System expansions and replacements: The 25-bundle format works for adding new stations to an existing Netafim drip network or replacing emitter assemblies that have accumulated mineral buildup after extended use.

If your grow room also uses an air pump to oxygenate reservoir water or relies on a reverse osmosis system for feed-water preparation, these drip assemblies integrate cleanly into that broader water management setup.
