Plastic 4 Tier Walk-In Greenhouse – 5ft x 7ft

The 3-tier walk-in polyethylene greenhouse  provides an excellent and useful place to develop and grow an array of fruits, vegetables, flowers, and seedlings. The framework that forms the structure itself and the material that covers it are the two main factors to take into account when selecting your greenhouse. The framework of our  Greenhouses is made of galvanised steel. Compared to materials like wood and plastic, steel’s inherent strength enables a considerably slighter, more open framework, meaning more wider spaces for sunlight to pass through. A reinforced polyethylene cover is then placed on top of the steel frame. Polyethylene greenhouses are generally more flexible and cost-effective than glass or solid plastic, and they can retain up to 40% more heat.
