Liquid foam makes for smarter greenhouses

While greenhouses allow certain crops to be grown throughout the year, excess temperature, solar radiation and high vapor pressure deficit can cause problems during the summer months. With conventional solutions, such as shade screens, often being labor intensive and reducing the quality of light within the growing space, Canadian company Sunarc has a developed a new liquid foam shading system that mimics cloud cover to automatically shade greenhouses. As the liquid foam filters the sunlight, it reduces solar radiation and controls temperature, but doesn’t deprive the plants of vital light spectra they require for photosynthesis.
