6m Pro-Series Polytunnel Greenhouse – 18 sqm Walk-In Growing Tunnel

Unlock true agricultural scale with the 6-Metre Pro-Series Polytunnel. This massive, walk-in greenhouse is the ultimate solution for serious horticulturalists looking to move beyond "hobby" gardening and into high-volume production. Offering a sprawling 18 sqm of protected ground space, it features a heavy-duty, grid-reinforced PE cover and a specialised 8-window ventilation system. Whether you're seeding thousands of starters or protecting a full-scale winter crop, this tunnel provides the durability and climate control of a traditional glasshouse at a fraction of the cost.


Best For

Serious home growers, small-scale market gardeners, and properties with large garden plots or acreage. Ideal for those requiring maximum horizontal space for row-cropping and large-scale seedling production.

Key Features

  • ✔ Massive 18 $m^2$ Growing Area: With a 6m x 3m footprint, this tunnel provides enough space for multiple rows of garden beds, central aisles, and staging benches.

  • ✔ 8-Window Cross-Ventilation System: Engineered for the Australian climate. Features four roll-up windows on each side, allowing for precision cross-flow ventilation to manage heat and humidity on scorching afternoons.

  • ✔ Grid-Reinforced PE Covering: The hard-wearing green polyethene cover is reinforced with a high-strength grid, providing superior tear resistance and UV protection compared to standard films.

  • ✔ Heavy-Duty 2m High Walk-In Frame: Supported by a sturdy, powder-coated tubular steel frame that provides a full 2-metre head clearance, ensuring a comfortable working environment for long gardening sessions.

  • ✔ Double-Zippered Roll-Up Door: A wide 160cm entrance allows for easy access with wheelbarrows and garden equipment, while the double-zipper system ensures a secure seal against pests and wind.

Oversize Item Delivery

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!

Shipping & Lead Times

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.
