With 112 sq. ft. of floor space plus a vaulted ceiling that offers plenty of space for trellising tall plants or climbing vines, the Palram Chalet Greenhouse Kit is just what you need to create the garden of your dreams. Two adjustable roof vents and double-swinging doors control heat and humidity while ensuring ample ventilation. Twin-wall 4mm polycarbonate roof panels protect from the heat of midday sunshine and retain warmth at night. The rugged, rust-resistant aluminum frame and polycarbonate side panels easily secure to the base while allowing for ample light transmission. Because setup is required, each kit also comes with an easy-to-read instruction manual. Galvanized steel base, wheelbarrow threshold ramp, two vent windows, manual adjustable window opener and magnetic door catch included. Limited five-year warranty. 95.25L x 143.75W x 78.75H.
