Providing an inert, airy and unobtrusive rooting environment, the excellent Rockwool growing medium has always perfectly suited hydroponic applications. Whether used as cubes to raise cuttings/seedlings and to establish these plants in main systems, or as slabs purposely designed for drippers, the tightly packed bundles of man-made fibres do a fine job supporting roots and rapid growth. The main advantages of Rockwool include its superb water to air retention properties (ensuring roots get the nutrients they need and a vital oxygen supply), compatibility with most growing systems, lightweight nature and cleanliness over alternative options.
