This 4 x 3m polytunnel greenhouse provides a spacious, protected environment for growing a variety of plants, flowers, and vegetables throughout the year.

• Galvanised Steel Frame: The structure features a strong galvanised steel core with four additional top rods for improved stability and support.
• Double-Door Access: Designed with two hinged doors and secure latches, allowing for easy entry and exit even when carrying tools or trays.
• Ventilation Control: Eight mesh screen windows provide essential airflow to regulate temperature and humidity while keeping pests out.
• Reinforced PE Cover: The durable PE cover allows 85% of sunlight to reach your plants while shielding them from harsher weather and maintaining internal heat.
• Extended Edges: The cover features 20cm extended edges designed to be buried in the soil, significantly increasing the overall stability and wind resistance.

This large walk-in greenhouse is designed for gardeners who need a reliable space to extend their growing season. The 4-metre length and 3-metre width offer ample room for staging, planters, or ground-level beds, while the interior height of 2 metres makes it comfortable to move around inside. The cover includes a middle reinforcement grid for added durability against the elements.

For the best results, it is recommended that two to three people assist with the assembly to ensure the frame and cover are correctly tensioned and secured. The green finish helps the structure blend into garden surroundings while providing the necessary environment for successful cultivation.
