The Comet greenhouse allows beginners to quickly get started with greenhouse gardening. The covering made of 4 mm thick, UV-stabilized twin-wall panels (TWP) provides solid insulation properties. The TWP not only cushions temperature drops at the beginning and end of the season and especially at night, but also protects your plants from excessive sunlight. Factors that beginners need not worry about too much if they have properly covered the greenhouse. Compared to glass, twin-wall panels are shatterproof and also lighter. The Comet is characterized by the attachment of the panels using a novel combination of insertion and clamping techniques. A smooth-running, ball-bearing sliding door with a width of 61 cm and a height of 161 cm provides convenient access and, together with the adjustable roof window, ensures optimal ventilation, especially on hot days. For the level and right-angled construction of the greenhouse, a foundation frame (H 12.5 cm) made of galvanized and powder-coated steel sheet is particularly helpful.
