Rion Grand Gardener Greenhouse

The twin-wall design creates an air pocket that acts as a thermal barrier, providing significantly better heat retention than single-pane glass or plastic. This helps maintain a more stable internal temperature for your plants during cooler shoulder seasons.

The heavy-duty extruded resin frame is engineered for durability and is rated to handle wind speeds up to 55 MPH and a snow load of 15 lbs per square foot. While robust, it is important to ensure the greenhouse is properly anchored to a level foundation to maintain these ratings.

The barn-style design is specifically intended to maximize vertical space, offering a peak height of 93.5 inches and a usable interior height of 7.5 feet. This makes it comfortable to walk through and provides ample room for taller plants or hanging baskets.

The three included roof vents are operated manually. You will need to open and close them based on your daily temperature and humidity monitoring to ensure your plants have the proper airflow.

As a freestanding structure, it should be installed on a solid, level surface such as a concrete slab, a pressure-treated wood frame, or a leveled gravel base. A secure foundation is essential for the stability of the resin frame and the proper alignment of the double doors.

The greenhouse uses a simplified pin-and-lock assembly system, which is designed to be more intuitive than traditional bolt-and-nut structures. While it is a significant project that typically requires two people, the system is engineered to streamline the connection of the resin frame and panels.
