For a premium greenhouse with zero hassle, choose the 6x6 Palram Canopia Rion EcoGrow Green Greenhouse (1.8m x 1.8m). This high-specification polycarbonate glasshouse is exceptionally easy to assemble, completely maintenance-free, and offers your plants the perfect conditions to thrive. This 6x6 greenhouse is expertly constructed from 4mm twin-wall polycarbonate roof panels and 6mm twin-wall polycarbonate side panels, supported by a UV-protected, green resin frame with pin and lock connectors. Rubber sealing strips provide enhanced insulation, while a reinforcement cable ensures first-rate structural stability. The light-diffusing polycarbonate panels promote an even temperature by increasing thermal insulation and reducing extreme sunlight exposure. They are completely UV-protected and shatterproof, and together allow 82% 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.

You can gain easy access through a single door, which includes a handle holder to keep it firmly in position when closed. Once inside, you\'ll find that the barn-shaped roof offers plenty of headroom, while the opening roof vent allows you to regulate the temperature for the benefit of your plants. 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 polycarbonate greenhouse is designed without a floor and that you should fix it to a solid, level base.
