Experimental greenhouse using hydroponic methods to grow garden produce such as tomatoes (right). The site at Cerro Prieto,Mexico,uses geothermal water from a neighbouring geothermal station to grow the produce hydroponically. The mineral rich waters are piped into the greenhouse & the plants are grown directly in the water. In this photograph a gravel layer covers the roots to prevent rapid evaporation | |
