Rock Wool

Rock wool, also known as mineral wool, is a fibrous material made from molten rock spun into fibers, used in landscaping as a growing medium, particularly in hydroponics and green roofs. It provides excellent water retention and aeration, promoting healthy root growth. Rock wool is also used as insulation in construction, but in landscaping, its primary use is to support plant growth in environments where soil is not ideal or space is limited. It is lightweight, sterile, and resistant to pests, making it a valuable material for sustainable gardening practices. However, handling rock wool requires care, as the fibers can be irritating to the skin and lungs.
