Heavy-Duty Black Poly Tubing – 19mm Horticultural Irrigation Line
Reliable fluid dynamics are essential for a high-performing garden. Our Heavy-Duty Black Poly Tubing is the industry-standard choice for mid-sized nutrient delivery lines and custom irrigation manifolds. With a 19mm diameter, this tubing offers the perfect balance between high-volume flow and manageable flexibility, making it the go-to size for many indoor grow tent configurations and greenhouse drip systems. The opaque black construction is engineered to block 100% of light penetration, effectively halting algae growth within your lines—a critical step in maintaining a sterile nutrient solution and preventing frustrating blockages in your drippers and emitters.
Best For: Secondary delivery lines, constructing manifold systems for 4–12 plants, connecting medium-flow pumps, and standard run-to-waste or recirculating hydroponic setups.
Key Features
- Light-Proof Algae Prevention: The deep black pigmentation prevents light from reaching your nutrient solution, stopping algae bloom in its tracks and protecting your root zone from pathogens.
- Versatile 19mm Diameter: Provides ample flow for multiple dripper sites while remaining easy to route around tent poles and corners, ensuring consistent pressure throughout your system.
- UV-Stabilised Durability: Manufactured from premium polyethylene designed to resist the intense radiation of LED and HPS lighting, ensuring the pipe won't crack or become brittle over time.
- Kink-Resistant Performance: Formulated for flexibility without sacrificing structural integrity, allowing for tidy, professional plumbing runs even in tight grow spaces.
- Standard Fitting Compatibility: Specifically designed to pair with all standard 19mm barbed irrigation fittings (Tees, Elbows, and Joiners) for a secure, leak-free installation.
- Inert & Safe: High-quality LDPE construction ensures that no harmful chemicals leach into your reservoir, preserving the purity and flavour of your final harvest.
Available Lengths
- 19mm x 10 Metre Roll: The ideal length for hobbyist tents (1.2m to 2.4m) and individual reservoir-to-tray connections.
- 19mm x 30 Metre Roll: Excellent bulk value for commercial facilities or growers managing multiple rooms and larger irrigation networks.
Specifications
- Diameter: 19mm (Internal Diameter)
- Material: Low-Density Polyethylene (LDPE)
- Colour: Opaque Black (Light-Proof)
- Pressure Rating: Optimized for standard horticultural water pumps
- Application: Hydroponics, Aquaponics, and Soil-based Drip Systems
Installation & Maintenance Tips
- Secure Connections: For a professional seal, use a cup of hot water to soften the end of the tubing before pushing it onto 19mm barbed fittings. This ensures a tight, leak-proof fit every time.
- Manifold Design: 19mm tubing is the ideal "secondary" line size; run it from a 25mm main line to create high-pressure manifolds for your individual plant sites.
- Seasonal Hygiene: Periodically flush your lines with a horticultural cleaning solution to remove mineral salt build-up and maintain maximum flow efficiency.
Ideal For (Uses)
- Drip Irrigation: Serving as the primary supply line for 4mm or 6mm micro-tubing take-offs.
- System Returns: Acting as a reliable drainage or return line for smaller flood-and-drain or top-feed systems.
- Pump Connections: The perfect fit for most standard 1000L/h to 3000L/h submersible pumps.

Oversized Item Delivery Options
Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.
Available options include:
✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Any carton or consignment over 25–30kg (or over 200cm) must be palletised
- Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
- Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
- Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions
Business Delivery:
- Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
- If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
See our Terms & Conditions (Article 8) for full freight and delivery rules.
Important Note on Availability & Shipping
Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).
How lead times work:
- Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
- Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
- Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
- Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
- Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.
Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.
