If you are buying a 1.6LPH drip line for greenhouse or nursery irrigation, start by matching the emitter flow rate, spacing, operating pressure, filtration, and line size to your crop layout. A 1.6LPH emitter releases approximately 1.6 liters per hour at its rated pressure, but actual discharge can vary with pressure, water quality, temperature, and product design. For many container nurseries, seedling areas, and closely spaced greenhouse crops, this flow rate provides a practical balance between controlled delivery and manageable irrigation duration.

I recommend treating the 1.6LPH rating as one part of a complete irrigation specification rather than choosing by flow rate alone. Before placing a bulk order, confirm emitter spacing, wall thickness, pressure range, roll length, material, filtration requirements, and connector compatibility. As a PE drip lines manufacturer and supplier, JINSHIDA can support buyers with product discussions, sample evaluation, packaging coordination, and project-specific specification review.
This guide is intended for greenhouse growers, commercial nurseries, irrigation distributors, agricultural contractors, and purchasing teams sourcing drip line in volume. It is also useful for buyers comparing standard 1.6LPH drip line with other flow-rate options for benches, grow bags, pots, propagation beds, and row crops. The recommendations are written for projects where repeatable irrigation and practical sourcing are more important than selecting the lowest unit price.
Small growers can use the same framework on a reduced scale, especially when they need to replace existing lines or standardize multiple greenhouse zones. Buyers should still verify local water conditions and installation requirements because no single drip line specification is suitable for every site. A short sample trial is often a more reliable decision tool than relying only on a catalogue description.
“1.6LPH” means that each integrated emitter is designed to discharge about 1.6 liters per hour under the manufacturer’s stated test conditions. The abbreviation LPH stands for liters per hour, while the distance between emitters determines how frequently water is distributed along the line. For example, a line with 1.6LPH emitters spaced every 30 centimeters delivers more outlets per meter than a line with the same emitter flow spaced every 50 centimeters.
The actual water delivered to a plant depends on the number of emitters, irrigation duration, and pressure at the line. A simple planning calculation is: total flow equals emitter flow multiplied by the number of active emitters. If one line contains 100 emitters rated at 1.6LPH, its nominal flow is approximately 160 liters per hour before pressure variation and system losses are considered.
Inline drip line has emitters installed inside the tube during manufacturing, creating a consistent outlet pattern along the roll. It is commonly considered for repeated greenhouse rows, nursery tables, and applications where installers want faster deployment. Online emitters are installed separately through a hole in plain polyethylene tubing, which can provide more flexibility for irregular plant spacing but requires additional labor and components.
For evenly spaced pots or crop rows, an inline 1.6LPH drip line may simplify installation and make purchasing easier. For mixed plant sizes or changing layouts, online emitters can offer greater adjustment potential. I suggest comparing the labor cost and layout flexibility, not only the price of the tubing itself.
Polyethylene is widely used for drip irrigation tubing because it is flexible, lightweight, and suitable for outdoor agricultural installation when properly specified. Material quality, wall thickness, manufacturing consistency, and resistance to handling damage can influence service performance. Buyers should request the product’s technical data sheet and confirm whether the selected wall thickness is intended for temporary, seasonal, or longer-term use.
Thin-wall drip line may reduce freight volume and initial material cost, while thicker-wall products may be more appropriate for repeated installation, exposed layouts, or projects requiring additional mechanical durability. The correct choice depends on pressure, installation method, UV exposure, storage practices, and expected service cycle. I avoid recommending a wall thickness without reviewing these conditions.
| Specification | Why It Matters | What to Confirm |
|---|---|---|
| Emitter flow | Determines water delivery per outlet | 1.6LPH rating and test pressure |
| Emitter spacing | Controls wetting pattern and outlet density | Spacing such as 20cm, 30cm, or 50cm |
| Tube diameter | Affects flow capacity and fitting compatibility | Nominal outside and inside dimensions |
| Wall thickness | Influences handling and expected service cycle | Measured thickness and product type |
| Pressure range | Supports correct emitter operation | Recommended inlet pressure and pressure regulation |
| Filtration requirement | Helps reduce clogging risk | Suggested filter grade and water treatment needs |
For greenhouse benches, grow bags, and container production, emitter spacing should follow the container arrangement rather than being selected independently. A 30-centimeter spacing may work for some closely arranged plants, while larger containers or wider spacing may require a different layout or multiple outlets. The objective is to place water where the root zone can use it without creating unnecessary wet areas between plants.
Because greenhouse crops may have different water requirements in the same facility, divide the irrigation system into zones whenever practical. A 1.6LPH line can be suitable for moderate, repeated applications, but irrigation duration should be adjusted through observation, substrate behavior, and crop requirements. I recommend confirming uniformity across the first and last sections of a test line before scaling the purchase.
Nursery rows often require a balance between installation speed and layout flexibility. Inline drip line can be efficient for regular rows, while propagation benches may benefit from closer emitter spacing or a layout designed around plug trays. Buyers should consider whether the product will be installed on the soil surface, suspended, pinned in place, or moved between production cycles.

For young plants, excessive discharge in a short period can cause runoff or disturb the growing medium. The 1.6LPH rate may be appropriate in some designs, but the final result depends on emitter count, substrate drainage, irrigation frequency, and pressure control. A small operational trial can identify whether the selected spacing delivers adequate coverage without overwatering.
Record row length, plant spacing, container dimensions, number of irrigation zones, and expected line length. Then estimate the number of emitters per line and the nominal flow for each zone. This information helps determine whether the proposed pump, valve, filter, and mainline can support the design.
Do not evaluate a 1.6LPH drip line without reviewing the available water pressure. Ask the supplier for the recommended operating range and whether pressure-compensating or non-pressure-compensating emitters are used. Filtration is equally important because suspended particles, algae, and mineral deposits can increase clogging risk, particularly in systems using surface water or recycled water.
Confirm the tube diameter, takeoff size, end closure, connectors, valves, and punch requirements before ordering. A fitting mismatch can create leakage, installation delays, or unplanned component costs. For export projects, also confirm roll dimensions, carton or woven-bag packaging, labeling, and pallet requirements in advance.
Before approving a large purchase, request samples for physical inspection and, where possible, a short field or greenhouse trial. Check the tube’s flexibility, emitter formation, outlet consistency, roll winding, and fitting compatibility. The supplier should be able to provide a product specification sheet that clearly identifies flow rate, spacing, dimensions, packing details, and applicable operating conditions.
The purchase price of 1.6LPH drip line depends on material consumption, wall thickness, emitter spacing, roll length, packaging, order volume, and customization. A closer emitter spacing generally means more emitters and more material per meter, so a lower price per roll does not automatically mean a lower cost per irrigated plant. Compare quotations using the same length, specification, packaging standard, and delivery terms.
Minimum order quantities can vary according to standard stock, color, dimensions, printing, and private-label requirements. Custom packaging or non-standard specifications may require additional production planning, while standard products may be easier to schedule. I recommend asking for a written quotation that separates product price, tooling or setup charges, packaging, inland transport, and export-related costs where applicable.
Lead time should be confirmed rather than assumed. A supplier may need different preparation time for standard production, customized rolls, inspection, and container loading. JINSHIDA can discuss the intended application, target specification, packaging expectations, and order schedule so buyers can evaluate whether the proposed supply plan fits their project.
When comparing manufacturers, I suggest evaluating more than catalogue breadth. Ask whether the supplier can explain how the 1.6LPH rating is defined, identify the recommended pressure conditions, and provide consistent product specifications. Also review communication quality, production planning, packaging control, inspection arrangements, and after-sales responsiveness.
For distributors and project contractors, customization may be important. Relevant options can include tube dimensions, emitter spacing, roll length, color, printed markings, carton design, and private-label packaging, subject to production feasibility. JINSHIDA’s role is to help buyers convert an irrigation requirement into a practical PE drip line specification and supply plan rather than simply quote an isolated product.
A 1.6LPH drip line can be a practical choice for many greenhouse and nursery irrigation systems when its spacing, pressure range, filtration, and tube construction match the application. It is not automatically the best option for every crop, container size, or water source, so the selection should be based on the complete irrigation design. The most reliable next step is to prepare your row layout, required roll length, emitter spacing, water conditions, and target order volume.
Send these details to JINSHIDA for a specification review and commercial quotation. We can help you compare suitable PE drip line options, identify the required supporting components, and plan samples before bulk purchasing. This approach gives greenhouse growers, nursery operators, distributors, and contractors a clearer basis for making a controlled and commercially sound decision.
