Give your plants the space and protection they need to thrive with this extra-large walk-in polytunnel greenhouse. Offering an impressive 12m² growing area, this robust greenhouse is ideal for cultivating vegetables, flowers, herbs, seedlings, and larger plants throughout the growing season.
Built around a reinforced galvanised steel frame, the structure provides exceptional strength and stability, while the durable 140gsm PE cover helps retain warmth and humidity, creating an ideal environment for healthy plant growth. The reinforced centre section keeps the cover securely in place, helping maintain protection against changing weather conditions.
The large walk-in design features a roll-up front door for easy access, alongside six mesh-covered ventilation windows that encourage airflow while helping keep insects and pests away from your plants. A 15cm extended ground skirt can be buried into the soil to improve stability and create a more secure seal around the greenhouse.
Supplied with ground stakes, guy ropes, plant labels, and gardening gloves, this practical growing solution contains everything needed to get started.
