Premium Gothic All-Metal High Tunnel Kit

Premium Gothic High Tunnel Greenhouse Kit

The gothic arch-style high tunnel is built for cold regions and heavier snow loads. Its high peak and steep rooflines help shed snow instead of allowing it to accumulate, reducing stress on the structure in winter. The steeper arch also creates taller end walls and more headroom, giving growers extra usable space inside for trellising, taller crops, and comfortable working height. 

This USA-manufactured system is designed for growers who want professional-grade durability and convenience from the start. This premium kit includes upgraded sidewall ventilation, a full truss package, reinforced corner bracing, multiple purlins, and fully fabricated metal end walls with a door, plus all required hardware and coverings.

Available in 14’ and 20’ widths, with lengths up to 100’.
