If you love growing plants and hate unnecessary hassle, the 8x20 Palram Canopia Rion Grand Gardener Greenhouse (2.67m x 6.39m) is for you. This extra-large polycarbonate glasshouse is exceptionally easy to assemble, completely maintenance-free and provides the perfect conditions for plants to thrive, making it every gardener\'s best friend. This wonderful 8x20 greenhouse is expertly constructed from 4mm twin-wall polycarbonate roof panels and 0.7mm crystal-clear polycarbonate side panels, supported by a UV-protected resin frame with pin and lock connectors. Rubber sealing strips provide enhanced insulation, while a reinforcement cable ensures superb structural stability. The light-diffusing roof panels promote an even temperature by increasing thermal insulation and reducing extreme sunlight exposure. Both roof and side panels are completely UV-protected and shatterproof, and together they allow 90% light transmission. This means your plants will enjoy optimum growing conditions, you will be protected from harmful UV rays, and the panels will neither discolour nor fade in the sun. Snow-load tested to 75kg/ m² (15.4lbs/ ft²), wind resistant to 90km/ hr (56ml/ hr), and with a roof which facilitates efficient rainwater runoff, this high-specification greenhouse will help your plants thrive, whatever nature throws at it. You can gain easy access to the interior via wide double doors, which include a handle holder to keep them firmly in place when closed. Once inside, you\'ll find that the roof\'s barn-shaped design provides plenty of headroom and the opportunity to grow taller plants. Four manually-opened roof vents help you regulate the temperature for their benefit. With a tool-free assembly and backed by a reassuring 7-year limited warranty, this polycarbonate greenhouse is completely maintenance free, saving you money and leaving you more time to nurture your plants. Please be advised that this greenhouse for sale is designed without a floor and that you should fix it to a solid, level base.
