Greenhouse building is seeing something of a boom all over the world as higher crop prices fuel grower confidence along with the increasing demand for food. In Holland, millions of euros are being spent expanding greenhouse facilities while here in the UK a sixth greenhouse has been confirmed for Thanet Earth. Each will be fitted out with yield- and quality-enhancing technology along with energy-saving systems.Today's greenhouses tend to be clad with glass, polyethylene or polycarbonate sheeting, but what will we be using in the future? We can already manipulate wavelengths entering a structure and perhaps we may see materials that can also generate energy tomake protected cropping more sustainable.
