Product Description

Expand your growing footprint with the 4.5' Extension Kit for the Alpine Series Greenhouse. This modular addition integrates seamlessly with TMG-GHA1111 greenhouse units, allowing you to increase cultivation space without installing an entirely new structure. Built with ultra-heavy-duty tubular aluminum, it maintains the series' high wind and snow load ratings.

Installation is fast and efficient through the quick-connect assembly system, utilizing pre-installed nuts to securely lock components into the existing frame. The extension kit also features the premium hybrid glazing design, combining 4 mm tempered glass walls for crystal-clear visibility with 6 mm hollow polycarbonate roof panels for enhanced insulation and climate control.

Two additional roof vents are included to improve airflow and environmental management, helping maintain optimal growing conditions throughout your expanded greenhouse space.
