Product Description
Product Description
The TMG-GHA1120 Alpine Series Greenhouse is designed to simplify your gardening experience while offering a professional, spacious, and versatile growing environment. The standout feature is the unique quick-connect assembly system, which utilizes pre-installed nuts within the connectors. This innovative design allows you to quickly lock the heavy-duty tubular aluminum profiles into place without the frustration of traditional sliding screws, making assembly remarkably fast.
Safety and durability are prioritized with a hybrid glazing configuration. The walls are fitted with 4 mm toughened glass, providing a crystal-clear view of your garden while ensuring long-lasting strength. The roof features 6 mm hollow polycarbonate panels to optimize insulation and protect plants from harsh sunlight. Combined with a sturdy iron base, this greenhouse remains stable and secure during adverse weather conditions such as high winds or heavy snow.
This 11.5' x 20.5' model offers generous headroom and a comfortable workspace for tending plants or simply relaxing inside the greenhouse. Six roof vents and two wall vents maximize ventilation, air circulation, and environmental control throughout the expanded growing area. The extra-wide double swing doors with a low-threshold design easily accommodate large items such as lawnmowers, grills, and bicycles.
The modular design also allows for future expansion, ensuring your greenhouse can grow alongside your gardening ambitions.
The TMG-GHA1120 is the combination of the TMG-GHA1111 greenhouse and two TMG-GHA11X Extension Kits. A medium-length version, the TMG-GHA1116, combines the base greenhouse with one extension kit for additional growing space.
We also offer smaller models, including the TMG-GHA0909, TMG-GHA0913, and TMG-GHA0918, which are compatible with the TMG-GHA09X Extension Kit.
