The Grand Gardener 2 Twin-wall is made with a heavy-duty extruded resin frame for improved insulation and durability. Virtually unbreakable twin-wall polycarbonate glazing creates a comfortable growing environment and diffuse light for even plant growth. The translucent, twin-wall polycarbonate panels also make superb, lightweight insulation.

The weatherproof frame on the Grand Gardener 2 features simplified assembly with the pin & lock system, while the roof panels now slide into place. A barn-style roof design provides ample headroom and gives you more space to garden. Double doors allow easy access and provide excellent ventilation. Included roof vent provides additional ventilation. Secure to a concrete pad or heavy timber foundation. The optional base kit may be added for different heights and extra stability.
