FAQs

How many people are recommended for assembly?

Assembly typically requires 2-3 people due to the size and components of the polytunnel kit.

What is the expected lifespan of the polythene cover?

The XL Horticulture SunMaster polythene cover has an expected lifespan of 7-10 years under normal conditions.

Does the kit include materials for doors?

The kit includes the structure components. If doors are not part of your specific package, you will need to source timber for doors, frames, and battens yourself.

What is the guarantee on the structure?

The polytunnel structure comes with a 5-year guarantee.

Can this polytunnel be used in very windy locations?

Yes, the aerodynamic design and heavy-duty galvanized steel ground tubes are specifically designed for stability in windy sites. For maximum security, consider hammering or concreting the ground tubes.

What are the benefits of the SunMaster polythene cover?

The SunMaster cover offers anti-condensation, anti-fog, and anti-drip properties. It provides thermicity greater than 65% and reduces temperatures in hot weather, optimizing conditions for plant growth.

How do I ensure the polythene cover is installed correctly?

The design allows for hoop adjustment after polythene attachment to maximize tension. Follow the included full-color instruction manual carefully, paying attention to achieving a tight fit.

Troubleshooting

Polythene cover is sagging or loose.

Adjust the hoops to increase tension on the polythene. Ensure all clamps are securely fastened. Check ground tube stability.

Frame appears unstable in windy conditions.

Verify all fixings are tightened. Hammer the ground tubes deeper into the ground or consider concreting them for maximum stability.

Condensation is excessive inside the polytunnel.

Ensure adequate ventilation by opening doors or vents during the day. The SunMaster cover has anti-condensation properties, but natural airflow is still important.

Difficulty in assembling the frame.

Refer to the full-color instruction manual with photos. Ensure you have adequate space and assistance from 2-3 people as recommended.

Pros and Cons

Pros

  • Durable and stable construction for all weather conditions.
  • Aerodynamic design reduces wind stress.
  • Adjustable frame ensures optimal polythene tension.
  • High-quality, long-lasting polythene cover with advanced properties.
  • Spacious interior provides excellent working height.

Cons

  • Requires 2-3 people for assembly.
  • Additional timber may be needed for doors and frames if not part of a specific package.
  • Ground tubes may need to be hammered or concreted for maximum stability.

Setup, Compatibility & Care

Setup:

  1. Clear and level the chosen site for the polytunnel.
  2. Assemble the galvanized steel ground tubes, ensuring they are securely placed.
  3. Erect the curved hoops and connect them using the provided fixings.
  4. Attach the polythene cover, utilizing the hoop adjustment feature to achieve maximum tension. This step is crucial for wind resistance and polythene longevity.
  5. Secure the polythene using the provided clamps and cast iron fixings. If doors are to be added, timber battens will be required to clamp the polythene to the door frames.
  6. The ground tubes can be hammered into the ground or concreted for enhanced stability, especially in exposed locations.

Compatibility:

This kit is designed to be a standalone structure. If you are not purchasing a package that includes doors, you will need to source timber to construct two doors and their frames, along with 2"x1" timber battens for securing the polythene on these doors.

Care:

  • Polythene Cover: Periodically inspect the polythene for tears or damage and repair promptly. Clean the cover with mild soap and water as needed to maintain light transmission. Avoid abrasive cleaners.
  • Frame: Ensure all fixings remain tight. The galvanized coating provides corrosion resistance, but occasional checks are recommended.
  • Ground Stability: If the structure is hammered into the ground, check its stability after strong winds. Consider concreting the ground tubes for permanent installations in high-wind areas.
  • Ventilation: Ensure adequate ventilation during warm weather to prevent overheating, which can stress plants and potentially degrade the polythene over time.
