If you're a home gardener, look no further for the ideal growing environment! An extra-wide, 40-inch growing space is protected by a PE cover to prevent sunburn and trap moisture. This feature provides ample space to trap heat and promote circulation. The flexible material works in concert with a four sturdy zipper system that helps you manage airflow and control both upper and lower access and comes with a set of touch fasteners to keep it open. The powder-coated steel frame uses PVC connectors and 16 shelf clips to keep the multi-panel shelves in place. This provides an easy assembly process and lets you remove panels to accommodate larger plants. Get your garden started the right way with a comfortable enclosure for plants to thrive!
