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
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.
