White Poly Tubing - 4mm Precision Micro-Irrigation – Heat-Reflective Feed Line (250m Bulk Roll)
Maintaining a cool and stable nutrient solution is critical for root health and oxygen absorption, especially in high-intensity grow environments. Our White 4mm Poly Tubing offers unique thermal benefits that make it a superior choice for both indoor and outdoor hydroponic gardening. The bright white exterior is engineered to reflect light and radiant heat, preventing the "solar oven" effect commonly seen with darker tubing. By keeping the solution inside significantly cooler, you reduce the risk of root pathogens and ensure your plants receive nutrients at an optimal temperature. This 250-metre commercial-grade bulk roll is the perfect solution for large-scale micro-drip systems where precision and environmental control are paramount.
Best For: High-heat indoor grow rooms, outdoor greenhouse fertigation, heat-sensitive hydroponic setups, and large-scale micro-drip installations.
Key Features
- Thermal Reflective Technology: The bright white outer layer reflects significant amounts of light and heat, helping to maintain lower nutrient temperatures and higher dissolved oxygen levels.
- Commercial 250m Bulk Value: Designed for large-scale operations, providing extensive reach for hundreds of individual plant sites with maximum cost-efficiency and minimal waste.
- UV-Stabilised Longevity: Contains high-quality UV stabilisers specifically formulated to prevent the tubing from becoming brittle or cracking under the intense radiation of LED, HPS, or direct sunlight.
- Precision 4mm Micro-Flow: The ideal diameter for "spaghetti" feeder lines, providing targeted nutrient delivery from your main distribution manifolds directly to dripper stakes and emitters.
- Light-Blocking Core: Despite the white exterior, the tubing is engineered to remain opaque, preventing light penetration and halting the growth of algae within your micro-lines.
- Superior Flexibility: Highly pliable and easy to work with, allowing for tidy routing around plant pots and grow tent infrastructure without kinking or restricting flow.
Specifications
- Colour: Bright White (Heat-Reflective)
- Diameter: 4mm (Internal Diameter)
- Length: 250 Metre Bulk Roll
- Material: UV-Stabilised Low-Density Polyethylene (LDPE)
- Application: Precision Micro-Drip, Fertigation, and Hydroponics
Installation & Maintenance Tips
- Heat Management: For best results in outdoor or greenhouse environments, use white tubing for all exposed runs to significantly reduce the heat load on your irrigation system.
- Soft-Fit Connection: Dip the ends of the 4mm tubing in warm water for a few seconds before pushing onto barbed fittings; this ensures a perfect, leak-proof seal as the plastic cools and contracts.
- Clean Cuts: Always use a sharp blade or dedicated tube cutter to achieve a square end. This ensures the tubing seats fully against the internal stop of your micro-fittings.
Ideal For (Uses)
- High-Intensity Grow Rooms: Managing nutrient temperature in tents where LED or HID lights generate significant radiant heat.
- Outdoor Drip Systems: Protecting your feed lines from the degrading effects of the sun while keeping the water cool.
- Precision Misting: Ideal for propagation systems where maintaining cool water temperatures is essential for successful cloning and seedling development.
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.
