The Grand Gardener® 8x16 Clear features 2 kinds of virtually unbreakable polycarbonate panels to give you the best of both worlds. Crystal-clear polycarbonate side walls allow clear views while being ultra-safe. While the twin-wall roof panels diffuse over 70% of sunlight for a soft, even light. The robust, UV protected resin frame of the Grand Gardener also features simplified assembly with the pin and lock system. The heavy duty extruded resin frame with its additional aluminium roof profiles improves both insulation and durability. The roof’s design provides ample headroom and gives you more space to garden. Double doors allow easy access and provide excellent ventilation. Included roof vent provides a heat vent even when the doors are closed. No-tool assembly makes the Rion Grand Gardener perfect for the growing enthusiasts needs.
