Hydroponic Soft Tube | Kink-Free Irrigation Hose 4mm–25mm Australia

Hydroponic Soft Tube. Kink-Free Flexible Irrigation Hose for Nutrient Delivery (4mm to 25mm)

Australian-made hydroponic soft tube engineered for efficient nutrient and water delivery across hydroponic, aquaponic, and irrigation systems. Designed with high flexibility and kink resistance, it maintains consistent internal flow and eliminates the coil memory issues common in standard irrigation tubing.

Available in four sizes covering the full range of hydroponic irrigation applications, from precision micro drip lines through to high-volume commercial mainlines. Optimised for Australian indoor grow tents, commercial greenhouses, and recirculating nutrient systems.

Key Benefits

• High-Flex Soft PVC Construction. Maintains flexibility across temperature variation without stiffening or cracking.
• Kink-Resistant Flow Stability. Eliminates flow interruption caused by tubing collapse in tight bends and corners.
• Coil Memory Reduction. Lays flat and routes easily during installation without springing back or holding a coiled shape.
• Compatible with Barbed Fittings and Manifolds. Standard fitment for all major hydroponic irrigation components.
• UV and Moisture Resistant. Stable performance in indoor and greenhouse environments under continuous nutrient solution exposure.
• Continuous Nutrient Delivery Capability. Engineered for long-term use in recirculating and run-to-waste hydroponic systems.

Available Sizes and Applications

• 4mm Soft Tube (100m). Micro feeder line for precision nutrient dosing, propagation systems, emitter-fed irrigation, and micro drip hydroponic setups. Ideal for connecting individual drippers to manifolds across multi-site systems.
• 13mm Soft Tube (30m). Standard distribution line for grow tents, reservoirs, and medium-scale irrigation systems. The most commonly used size for general hydroponic system builds.
• 19mm Soft Tube (30m). Medium flow line for nutrient transfer between reservoirs, pumps, and manifold distribution systems. Suited to greenhouse and mid-scale recirculating setups.
• 25mm Soft Tube (30m). High-volume mainline transfer hose for commercial hydroponic irrigation networks and large-scale systems requiring maximum flow capacity.

How It Works

Hydroponic soft tube maintains consistent internal diameter under pressure and across bends, ensuring stable flow rate delivery from pump to plant site. The kink-resistant PVC compound prevents wall collapse in tight routing scenarios, which is a common cause of flow interruption and uneven nutrient distribution in drip and recirculating systems. The reduced coil memory allows the tube to be routed and fixed in position without constant tension pulling it back to its coiled shape, reducing installation time and improving long-term system reliability.

System Features

• Hydroponic-grade flexible PVC. Nutrient and corrosion resistant.
• Kink-resistant wall construction for stable flow in tight bends
• Reduced coil memory for fast, clean installation
• Compatible with barbed fittings, manifolds, and irrigation connectors
• UV stabilised for indoor and greenhouse use
• Suitable for low to medium pressure hydroponic systems

Applications

• Drip Irrigation Systems (Run-to-Waste and Recirculating)
• Deep Water Culture (DWC) Reservoir Feeds
• Recirculating Hydroponic Systems
• Ebb and Flow (Flood and Drain)
• Propagation and Cloning Systems
• Aquaponic Systems
• Greenhouse and Commercial Irrigation Networks
• Automated Dosing and Fertigation Systems

Size Selection Guide

• 4mm (100m). Micro drip lines, emitter feeds, propagation systems.
• 13mm (30m). Standard grow tent and reservoir distribution lines.
• 19mm (30m). Medium-volume reservoir-to-manifold transfer.
• 25mm (30m). Commercial mainline and high-volume nutrient transfer.

What Sets It Apart

Standard irrigation tubing is often repurposed from garden or agricultural applications and lacks the flexibility and kink resistance required for the tight routing common in indoor grow tents and commercial hydroponic racking systems. This soft tube is specifically engineered for hydroponic environments, with a PVC compound that remains flexible at room temperature, resists kinking in 90-degree bends, and holds its shape after installation without coil tension pulling fittings loose. The 100m roll on the 4mm size provides enough volume for a complete multi-site drip system build in a single order. The 30m rolls on 13mm, 19mm, and 25mm cover standard grow room and commercial greenhouse builds without excess waste.

Frequently Asked Questions

What size fittings do I need for Hydroponic Soft Tube?

Hydroponic irrigation fittings are sized by internal diameter — common sizes are 4mm, 13mm (½"), 19mm (¾"), and 25mm (1"). Match fittings to your existing tubing or pump outlet diameter. When in doubt, 13mm is the most common size for standard hydroponic systems and is compatible with most pumps and mainline tubing in the 300–2000 L/hr flow rate range.

How do I prevent leaks with Hydroponic Soft Tube?

Push-fit barbed fittings should be inserted firmly until they bottom out against the shoulder. Soft poly tubing grips barbs securely without clamps for most low-pressure applications. For higher-pressure or constant-run systems, add hose clamps over the barb connection for a leak-free seal. Always pressure-test your system for 30 minutes before introducing plants.

Does Hydroponic Soft Tube ship fast within Australia?

Yes — Hydroponic Soft Tube ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
