Outsunny Walk In Polytunnel Greenhouse 6 x 3 m With Zipped Doors 8 Mesh Windows PE Cover White

Extend your growing season and protect your plants with the Outsunny Walk-in Polytunnel Greenhouse. This 6 x 3 m white tunnel delivers a reliable, sheltered microclimate that helps seedlings thrive, harden off faster, and keep crops productive well into cooler months. With a walk-in design, you’re free to arrange your space inside exactly how you want it—benches, trays, and shelving included—so you can tailor the setup to your garden or greenhouse workflow.

Robust, wind-ready structure for year-round growing

Built around a galvanised steel frame, this polytunnel stays in shape through changing conditions. Reinforcement slant bars add stability, while long edges are designed to be buried into the soil and secured with four ground stakes and four guy ropes. The result is a sturdy, wind-conscious shelter you can rely on, even when the weather shifts.

Protective shell with practical ventilation

• PE cover (140 GSM) provides UV protection and a light shield from mild weather, creating an ideal environment for plant growth.
• Eight mesh windows enable natural airflow to prevent humidity buildup and promote healthy transpiration, all while keeping insects at bay.
• Zipped roll-up doors offer easy, hands-free entry and adjustable ventilation to regulate temperature and airflow as needed.
• Durable polyester seam reinforcement adds longevity for regular use season after season.
• Windproof level 4-5 when fully fixed ( wind speeds below 17.5 mph) gives you confidence during breezy days.
