Often a strong fit for
- Large vegetable patches

This 4-metre walk-in polytunnel provides a spacious and controlled environment for growing fruits, vegetables, and plants. It features a built-in irrigation system and a reinforced 140gsm cover to protect your crops throughout the growing season.
- Integrated Sprinkler System: Features a built-in water pipe that allows for consistent hydration of your plants without the need for manual watering inside the tunnel.
- Reinforced 140gsm Cover: The durable plastic cover includes a reinforcement grid to prevent tearing and provide long-lasting protection against the elements.
- Galvanised Steel Structure: Constructed with a strong galvanised steel frame and diagonal bracing rods for increased stability and resistance to rust.
- Mesh Windows and Wide Door: Includes mesh windows for essential airflow and a large zipped door for easy walk-in access and ventilation management.
Designed for durability and ease of use, this greenhouse uses a heavy-duty 140gsm PE cover that allows sunlight to reach your plants while shielding them from wind and birds. The walk-in design, standing at nearly 2 metres tall, ensures you have plenty of room to work and space for taller plant varieties.
The structure is supported by a galvanised steel frame, which is engineered to stand steady in typical British garden conditions. The inclusion of an internal watering pipe simplifies the setup for automated or easy-access irrigation, making it a practical choice for serious home growers and allotment holders.
