Backyard Discovery Aggie Cold Box

The hinge uses a specialized wax-filled cylinder that expands as the temperature rises, physically pushing the lid open. As the air cools, the wax contracts, allowing the lid to close automatically, which keeps your plants protected without needing any power source.

Yes, the frame is built from durable cedar, which is naturally resistant to rot and decay. The structure is further reinforced with powder-coated steel hardware to prevent rust and ensure it holds up well across changing seasons.

Double-wall polycarbonate provides superior insulation compared to single-pane glass or plastic, helping to trap heat inside during colder days. It also diffuses sunlight, which prevents your seedlings from getting scorched while still allowing enough light transmission for healthy growth.

The Aggie Cold Box is a self-contained planter box with an integrated drainage system and mesh liner. This means it holds its own soil and can be placed on a patio, deck, or directly on the ground while keeping your plants contained and well-drained.

The unit measures 48 inches wide by 28.75 inches deep. Given its 32-inch height, it is designed to be compact enough for small backyards or patios while still offering enough depth for root development.

Assembly is required and involves multiple components, including the cedar frame and the polycarbonate lid. While one person can manage it, having a second person to help align the panels and attach the lid mechanism will make the process significantly easier.
