Carefully engineered to perform in the harshest environments, the 1.6mm profile aluminum frame provides a stronger and more durable build than its competitors. The heavy-duty construction coupled with 6mm twin-wall polycarbonate panels results in outstanding thickness for winter insulation.

A wide range of features and accessories culminates in a well-ventilated growing space with gliding double doors, an easy-to-assemble system, and an estimated insulation R-VALUE* of 1.54 and heat loss U-VALUE* of 0.65, providing an amazing gardening and greenhouse experience.

The doors hang from above, eliminating jamming, and the wheels are nylon for durability.
