Details

Extend your growing season and create a controlled planting environment with the SummitLine Heavy-Duty Tunnel Greenhouse, engineered for gardeners who need generous interior space and year-round protection. Designed with a galvanized steel frame, this polytunnel greenhouse resists chipping, peeling, and weather exposure, while multiple reinforcement bars— including four slanted bracing tubes, a front crossbar, and center supports—help increase overall stability.

The transparent PE cover filters sunlight while shielding plants from wind, temperature swings, and mild precipitation. Eight roll-up mesh-screened windows allow cross-ventilation to help regulate heat and humidity, while the large zippered front door allows easy entry and can be secured open for airflow.

This walk-in greenhouse includes two installation options: anchor directly into soil or secure onto a hard surface. For additional stability, four screw-in ground stakes, four supporting rods, and an extended cover perimeter are included for improved anchoring.
