Rock wool Cubes are the most common type of hydroponic growing medium. It is made up of tiny little fibers that are braided together. Rock wool is very easy to use inexpensive and easy to handle. Simply soak the cube in nutrient solution and place it in hydroponic system reservoir. The blocks will absorb water and dissolve the nutrients into the solution, after which they simply need to be topped off with more water periodically for a continuous supply of nutrients. Be careful not to damage at the time of transplanting plants from a system to another or from root tubes to rock wool cubes
