Rock-wool holds lots of water and air for fast rooting and growth. Grodan Rock-wool Cubes are perfect for growing your rooted cuttings before transplanting into your hydroponics system. The Rock-wool is finely spun and is of high quality, and the hole in the top of the cubes is ideal for starting off seeds or rooting your cuttings in.

For best results, soak the large-hole rock-wool cubes in very weak nutrient solution or water which has been pH adjusted to about 5.5 and leave overnight. Before use, shake out excess nutrient solution. Cuttings can then be placed directly into the pre-soaked cubes. Seeds can be dropped in to start them off. Once your cuttings are rooted through, they can be transferred into soil, coco or a larger rock-wool cube.
