Product Description

The TMG-GHA1111 Alpine Series Greenhouse is designed to simplify your gardening experience while providing a professional, spacious, and versatile growing environment. Its standout feature is the innovative quick-connect assembly system, which uses pre-installed nuts within the connectors. This design allows the heavy-duty tubular aluminum profiles to lock into place quickly without the frustration of traditional sliding screws, making assembly significantly faster and more efficient.

Safety and durability are prioritized through a hybrid glazing configuration. The walls are fitted with 4 mm tempered glass, providing crystal-clear visibility while ensuring long-lasting strength and durability. The roof uses 6 mm hollow polycarbonate panels to improve insulation and help protect plants from harsh sunlight. Combined with a sturdy iron base, this greenhouse remains stable and secure during demanding weather conditions such as strong winds and heavy snow.

This 11' x 11' model offers generous headroom and a comfortable workspace for gardening and everyday use. The extra-wide double swing doors with a low-threshold design allow easy access for larger items such as lawnmowers, grills, bicycles, and gardening equipment. Its modular design also allows for seamless future extensions, enabling the greenhouse to expand with your gardening needs.

TMG Industrial also offers the TMG-GHA11X 4.5' Extension Kit for this greenhouse, along with the smaller TMG-GHA0909 Alpine Series Greenhouse.
