Backyard Discovery Aggie Cedar Wood Cold Frame Greenhouse

The lid is equipped with a temperature-sensitive hydraulic cylinder. As the internal temperature rises, the fluid inside the cylinder expands, pushing the piston to open the lid automatically; as it cools, the fluid contracts and the lid closes.

Yes, cedar is naturally resistant to rot, decay, and insect damage, making it an excellent choice for outdoor garden structures. While it is durable, applying a wood sealant or stain annually will help maintain its color and extend its lifespan even further.

At nearly 95 pounds, this unit has significant weight, which helps keep it stable. However, if you live in an area with high winds, you may want to place it in a sheltered spot or consider adding additional anchoring to the steel legs.

While the structure is designed as a complete cold frame, the lid is hinged and can be opened or propped. If you prefer to use it as a standard raised bed, you can keep the lid open or remove it entirely, though the unit is optimized for its greenhouse functionality.

The double-wall design creates an air pocket that acts as insulation, which is significantly more effective at retaining heat than single-pane glass or plastic. This allows you to maintain a warmer environment for your seedlings even when outside temperatures drop.

Assembly is required and involves putting together the cedar frame, attaching the steel legs, and installing the polycarbonate panels. You will need basic tools like a screwdriver and potentially a drill, and it is recommended to have a second person help with the alignment of the panels and lid.
