Cellular glass gravel used in the vegetable industry

logo_smallSGGC  (SchaumGlas Global Consulting GmbH) installed a production line for cellular glass gravel in the USA. The line is used for  hydroponic applications. This is a subset of hydroculture where plants are grown without soil. In this case, the roots are supported by the (cellular glass) gravel and have access to much more oxygen and exactly the amount of water they need.
