* [1] Rockwool can be used to anchor cut flowers. [2] It also is a growing medium for plants. [3] It particularly is popular for growing plants under soil-less conditions, and in water. In soil-less conditions, it can take the place of peat. That's considered environmentally friendly, since peat bogs aren't renewable. Rockwool absorbs nutrients, and holds water without becoming waterlogged. [4] And it also is used to improve permeability in raised beds, or in soil. For it allows plants to root, without becoming deformed or stunted by trying to grow under compacted or crusted conditions. * its also used for sound insulation
