Netafim .5 GPH Single Drip Stake Assembly – 48 in (25/Bundle)

The Netafim .5 GPH Single Drip Stake Assembly delivers a consistent, measured water supply directly to the root zone of each plant. Each assembly includes a 0.5 GPH pressure-compensating emitter with CNL check valve, 48 inches of Super Flex Tubing, and an angled barbed stake — everything needed to run a single drip line from a main supply to a container or media bed. Sold in bundles of 25 to simplify setup across multi-site grows.

Netafim .5 GPH Drip Stake Assembly Specifications

Specifications are drawn from the manufacturer canonical data and the product description. This listing covers the 48-inch, 0.5 GPH configuration in the 25-unit bundle.

Why Choose the Netafim .5 GPH Drip Stake Assembly

Netafim drip stake assemblies are designed to cut installation time on multi-plant irrigation setups. Because each assembly arrives pre-built — emitter, tubing, and stake together — there is no field assembly required. You run the tubing to the plant site, press the barbed stake into the growing media, and connect the opposite end to the main supply line.

The pressure-compensating emitter holds a steady 0.5 GPH output across a range of line pressures above the 10 psi minimum. This matters in longer runs or gravity-fed systems where pressure varies between the first and last emitter in a row. The CNL (check-valve no-leak) design prevents dripping at the emitter when the system shuts off, which reduces waterlogging and keeps media moisture levels more predictable between irrigation cycles.

• Pre-assembled with emitter, 48-inch Super Flex Tubing, and angled stake — no field assembly needed
• Pressure-compensating emitter maintains 0.5 GPH over a range of line pressures (10 psi minimum)
• CNL check valve stops dripping when the system is off, protecting roots from oversaturation
• Angled barbed stake anchors securely in coco coir, perlite, rockwool, and similar media
• 25-unit bundle sized for rows, benches, or full-room setups without repeated reordering

Best Uses for the Netafim .5 GPH Drip Stake Assembly

This assembly suits any recirculating or run-to-waste drip system where each plant needs an individual emitter point. Common applications in controlled-environment agriculture include:

• Coco coir container grows — the 48-inch tubing reaches containers arranged across a standard flood table or tray without kinking
• Rockwool slab irrigation — the barbed angled stake pins into slab surfaces to deliver water at the root collar
• NFT and hybrid systems — use as a top-drip feed on systems that rely on both film flow and point-source drip
• Multi-plant benches — the 25-unit bundle covers a full bench row in one order, reducing freight costs versus buying individually
• Run-to-waste setups — consistent pressure compensation prevents uneven distribution across long manifold runs

If your system also requires water quality monitoring before the manifold, a reverse osmosis filtration unit can reduce mineral buildup at the emitter tip over time. For systems that use in-line filtration, pairing with a 200-mesh in-line filter before the drip manifold helps protect the small orifice from particulate clogging.

Compatibility & Operating Range

The assembly connects to standard 1/4-inch or 1/2-inch poly drip supply tubing via the barbed inlet on the emitter end. The angled barbed stake is designed for insertion into porous growing media (coco, perlite, rockwool, expanded clay, or peat-based mixes). It is not intended for open-water systems where the stake cannot anchor.

The pressure-compensating emitter requires a minimum of 10 psi at the inlet to function correctly. Below this threshold, flow rate will drop below the rated 0.5 GPH and emitter uniformity will decrease. Most submersible irrigation pumps running a properly sized main line will exceed this requirement. Netafim also offers a 0.3 GPH version of this assembly and a 36-inch tubing variant for tighter spacing; confirm which flow rate and tubing length your layout requires before ordering.

The Super Flex Tubing is flexible enough to route around containers and obstacles without sharp-bend kinking, which is relevant when the 48-inch length must navigate around a tray edge or bench support.

How to Install the Drip Stake Assembly

1. Prepare the main supply line. Run your main poly drip tubing across the grow area. Verify system pressure is at least 10 psi at the manifold before connecting emitters.
2. Punch or insert the emitter inlet. Use a punch tool to make a hole in the main supply line, then insert the barbed emitter inlet firmly until it seats. Alternatively, connect to a pre-drilled manifold fitting.
3. Route the Super Flex Tubing. Guide the 48-inch tubing from the emitter to the target plant container or slab. The tubing is flexible and can curve around tray edges without kinking.
4. Insert the angled barbed stake. Press the stake into the growing media at the base of the plant, angling it toward the root zone. The barbs hold the stake in place in coco, rockwool, and perlite.
5. Start the system and verify flow. Run the irrigation cycle and confirm each stake assembly is dripping at the emitter tip. The CNL check valve will stop flow within seconds of the pump shutting off.
6. Check uniformity across the row. After the first full cycle, inspect each emitter. Pressure-compensating emitters should show consistent wetted spots in the media. Uneven spots indicate a connection leak or pressure below 10 psi.
