Acerca de Sigma Small Compact (Gen III)

The Sigma Small Compact (Gen III) brings the strength and durability of the Sigma series into a perfectly square 6.5' x 6.5' design. Its space-efficient footprint makes it ideal for patios, smaller backyards, and urban properties while still providing ample room for shelving, raised beds, or container gardening.

With the same durable aluminum frame and twin-wall polycarbonate glazing used across the Sigma line, this greenhouse is built to support healthy plant growth through changing seasons.

Exact size: 78.7 x 78.7 x 94.5 inches

The durable galvanized steel frame is designed for long-term performance and resistance to rust and corrosion. Engineered for strength, it helps the greenhouse withstand moderate to severe weather, providing dependable protection for your plants throughout the seasons.

The greenhouse comes with:
  • two doors
  • two manual windows
  • the option to install multiple windows.

With end-to-end airflow and a generous peak height of 7.8' (2.4m), the Sigma Small Compact offers a comfortable interior workspace, allowing you to move freely while maintaining proper temperature circulation throughout the day.
