The Grand Gardener 8x20 Clear greenhouse from Palram offers a dual-panel system for optimal plant growth. Its crystal-clear polycarbonate side walls provide unobstructed views, while the twin-wall roof panels diffuse sunlight for even light distribution. The UV-protected resin frame features a simple pin and lock assembly system, enhanced by extruded resin and aluminum roof profiles for improved insulation and durability. The roof design ensures ample headroom, and double doors offer convenient access and ventilation. An included roof vent regulates temperature even when doors are closed. This greenhouse is ideal for gardeners seeking to extend their growing season and achieve consistent results with easy, no-tool assembly.
