The polytunnel has T-shaped anchors on the vertical beams dug into the ground. For those seeking extra stability, angle brackets allow for installation on a solid base.

The UV-treated, double-walled polycarbonate comes with a reassuring 5-year warranty. This material offers superior impact resistance and insulation compared to traditional glass while remaining pleasantly lightweight.

Stainless steel baselines and ground-anchored vertical beams ensure your polytunnel stands firm against the elements.

The doors feature clever ventilation panels at the top. Open them to encourage airflow, facilitate pollination, and maintain optimal temperatures during warmer spells.
