Rockwool cubes are a must-have for anyone looking to raise seedlings and cuttings in their hydroponic setup. They are ideal for hydroponic gardening because of their great moisture and oxygen retention without ever impeding the development of roots.
These wrapped cubes are the ideal size for starting seeds or propagating cuttings, as well as being adaptable to almost any growing setup. Once roots emerge you will need to plant them into larger Grodan Transplanting Cubes or another growing medium.
