Description

Offering the perfect environment for your plants to prosper, the 6’ x 12’ Palram Canopia Harmony Large Green Polycarbonate Greenhouse (1.85m x 3.70m) combines an attractive traditional design with the use of high-specification materials throughout. A Premium Polycarbonate Greenhouse Using the latest Fine Shield Technology™, this 6 x 12 greenhouse is expertly built from crystal-clear, shatterproof polycarbonate panels, which provide 90% light transmission, block 100% of harmful UV rays, and will neither fade nor discolour in the sun. The heavy-duty, silver aluminium frame and galvanised steel perimeter base are equally robust and impervious to rust. This premium build results in a near-unbreakable greenhouse, which will remain a much-loved feature of your garden for decades to come. Snow-load tested to 75kg/m² (15.4lbs/ft²) and wind resistant to 90km/hr (56mi/hr) too, this polycarbonate greenhouse provides supreme weatherproof protection for your plants. It is designed with a traditional apex roof for effective rainwater runoff, and to nicely round off its exceptionally attractive appearance. Entering the Greenhouse You can gain easy access to your plants through a single door, which can be fitted with a left- or right-hand opening to suit the orientation of your garden. This door includes a magnetic catch and padlock fixing (padlock not included), so rest assured that your valuable tools and invaluable plants will remain safe from unwanted attention. Greenhouse Vents and Guttering This large greenhouse features two manually opened roof vents to help you regulate the temperature inside the greenhouse. It comes with integral guttering too, offering you a free and sustainable supply of water for your garden, when connected to a water butt. Installing the Greenhouse Backed by a reassuring 5-year limited warranty, this polycarbonate and aluminium greenhouse is completely maintenance free, saving you money and leaving you more time to nurture your plants. The high-impact polycarbonate panels are pre-cut and have uniform profiles, so are simple to slide into place for a straightforward assembly. Please be advised that this greenhouse for sale is designed without a floor, and that you should secure it to a solid, level surface. The galvanised steel perimeter base includes anchor holes for this purpose (you can buy an anchor kit as an optional upgrade).
