Heavy-Duty Black Poly Tubing – 6mm Precision Micro-Irrigation Line
Precision at the plant site is the key to uniform growth and maximum yields. Our Heavy-Duty Black 6mm Poly Tubing is the professional choice for "spaghetti" lines and micro-irrigation setups. Designed to connect main distribution lines directly to individual drippers, stakes, or emitters, this tubing provides the targeted delivery required for high-frequency fertigation. The opaque black construction is engineered to be 100% light-proof, preventing algae growth within the micro-lines—a critical factor in avoiding the frustrating blockages that can lead to underwatered plants and crop loss. Flexible, durable, and easy to work with, this 100-metre bulk roll is the essential plumbing solution for any precision-focused grow room.
Best For: Individual plant "feeder" lines, connecting micro-drippers and stakes, precision fertigation systems, and DIY hydroponic manifolds.
Key Features
- 100% Light-Proof Algae Protection: The dense black pigmentation blocks all light penetration, ensuring your micro-lines remain clean and free from the algae build-up that typically clogs small-diameter emitters.
- Superior Micro-Flexibility: Engineered for maximum pliability, allowing you to navigate tight turns and intricate plant layouts without kinking or restricting the vital flow of nutrients.
- UV-Stabilised Performance: Manufactured from premium-grade polyethylene designed to withstand the intense radiation of LED and HPS lighting, ensuring the tubing won't become brittle or snap over time.
- Standard 6mm Compatibility: Perfectly fits all standard 4mm/6mm barbed micro-fittings, dripper stakes, and "take-off" connectors for a secure, leak-free installation.
- Bulk 100-Metre Value: The ideal choice for commercial facilities or large-scale multi-pot systems, providing ample length to reach every corner of your facility with zero wasted material.
- Inert & Chemical Resistant: Constructed from high-quality LDPE that is resistant to the acids and mineral salts found in concentrated hydroponic nutrients, preserving the integrity of your solution.
Available Options
- 6mm x 100 Metre Roll: The industry-standard bulk roll for large-scale installations and professional irrigation builds.
Specifications
- Diameter: 6mm (External) / 4mm (Internal)
- Material: Low-Density Polyethylene (LDPE)
- Colour: Opaque Black (Light-Proof)
- Length: 100 Metre Bulk Roll
- Application: Micro-Drip Irrigation and Hydroponics
Installation & Maintenance Tips
- The "Hot Water" Trick: If you find the tubing difficult to push onto micro-fittings or drippers, dip the end in hot water for 10 seconds to soften the plastic for an easy, airtight seal.
- Square Cuts: Always use a sharp blade or dedicated tube cutter. An angled cut can lead to poor seating on the barb, increasing the risk of leaks under pump pressure.
- Manifold Balancing: Ensure all 6mm feeder lines from your main manifold are of equal length. This helps maintain consistent pressure and volume (uniformity) to every plant in the system.
Ideal For (Uses)
- Drip Stakes: Connecting 19mm or 25mm main lines to individual pressure-compensating (PC) drippers.
- Top-Feed Systems: Delivering nutrient solution directly to the root zone in coco-coir, rockwool, or perlite-based setups.
- Micro-Sprinklers: Ideal for low-pressure misting or cloning systems where precision water delivery is required.
Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.
Available options include:
✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ 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
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
- Business delivery customers must provide a valid business address and contact information
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
Let us know your preference, and we'll arrange the best solution for you!
Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
