Description

The Elite Zenith 8x18 Greenhouse is the pinnacle of the 8ft range, delivering unmatched height, space, and versatility for serious gardeners. Standing 8’5” wide with an impressive 18-foot length, this model offers extraordinary growing volume and a soaring ridge height of 3160mm. The large interior is ideal for cultivating tall crops such as tomatoes, grapevines, or fruit trees while providing ample space for vibrant flower displays, herbs, and large vegetable patches. The Zenith’s towering design accommodates vertical growth and ensures exceptional airflow, creating a healthy and balanced environment for plants to thrive.

Engineered with the strength of Elite’s renowned Titan series, the Zenith features a reinforced aluminium frame, strengthening cantilevers, and high-tensile nuts and bolts for unwavering durability. This greenhouse is designed to handle challenging weather conditions with ease. A low-threshold entry makes accessing the space effortless, whether you’re moving tools, pots, or wheelbarrows. The integral base and gutters add further stability and allow for simple rainwater collection, supporting sustainable irrigation.

The greenhouse is equipped with thoughtful features to optimise growing conditions. A combination of automatic roof vents and a ten-blade louvre vent promotes steady airflow, regulating temperature and humidity for healthier, more productive crops. Bar capping and canopy seals enhance the structure’s resilience, offering a clean, weatherproof finish that will stand the test of time.

Standard toughened glass is included, this is an outstanding choice for greenhouses, providing numerous advantages over horticultural glass. Its superior durability and safety set it apart as an ideal option. Unlike regular glass, toughened glass boasts a high resistance to breakage. In the rare instance it does break, it shatters into smaller, less hazardous pieces, minimising the risk of injury. This perfect balance of strength and safety ensures a more secure and long-lasting greenhouse structure.

Included is a standard rainwater kit.  Each kit includes all the necessary components for efficient rainwater collection into a barrel or another designated outlet, ensuring a seamless and effective water collection process.

Personalise your Zenith to suit your garden’s aesthetic with nine powder-coated colours, including earthy Mocha, elegant Graphite, and deep Navy. The traditional alloy silver finish is also available for a classic and timeless appearance. 

With British manufacturing, the Elite Zenith 8x18 Greenhouse is the ultimate solution for gardeners who need maximum space and performance. Whether you’re growing fruit trees, cultivating climbing crops, or experimenting with exotic plants, this greenhouse combines impressive height, robust construction, and vast growing potential to help you achieve extraordinary results.

Base Options

Selecting the right base when installing your Elite Greenhouse is crucial for stability and long-term use. One of the most popular methods is to create a level, flagged area. Making the slabbed surface slightly larger than the greenhouse dimensions is recommended, as the listed measurements are nominal, and the actual structure may be a few inches larger. Refer to the metric measurements on the specifications table to ensure you make the base the right size. For instance, for an 8’x6’ greenhouse, a slab area of 10’x8’ is ideal, allowing space for positioning water barrels and providing access for cleaning and maintenance.

If you are constructing your greenhouse on soft ground, such as soil or grass, solid support under the door cill is essential to prevent damage from repeated use. This can be achieved by placing flags under the cill or using Elite’s soft soil support, ensuring the door(s) run smoothly on the track. Whether installed on a hard or soft surface, Elite provides options to securely anchor the base, ensuring a stable foundation.

NOTE: If you are situating your greenhouse on a brick wall the brick base must be exact. The integral base will not be required.  Please use our 'Contact Us' form to inquire about the correct base size.

Aluminium Greenhouse Maintenance 

Maintenance and care are essential for prolonging the lifespan of your Elite Greenhouse. The upkeep is simple but can ensure your greenhouse serves you for many years, even decades. Cleaning your greenhouse is crucial in enhancing the plant-growing environment by eliminating algae, moss, and grime. It allows more light in and also helps in managing pests and diseases. To maintain your greenhouse effectively, start by temporarily relocating your plants. Use a brush to clean tabletops, remove cobwebs from corners, and eliminate floor debris. Ensuring clean windows inside and outside is vital for maximising light levels. You can clean the glass, aluminium, and plastic surfaces with a microfibre cloth, using hot, soapy water or a commercial greenhouse cleaning product. Rinse with clean water and let it dry.
