Rock-wool holds lots of water and air for fast rooting and growth. Our Rock-wool cubes are perfect for growing your rooted cuttings in before transplanting into your hydroponics system. The Rock-wool is finely spun and of high quality and the hole in the top will take either a 1/2-inch or 1-inch rooting-cube (depending on your selection).

For best results, soak the large-hole rock-wool cubes in weak nutrient solution which has been pH adjusted to about 5.5 and leave overnight. Before use, shake out excess nutrient solution. Rooted cuttings can then be placed directly into the pre-soaked rock-wool cube.

The cuttings can then be grown into slightly larger plants until they are rooted through. When roots appear on the outside of the large-hole rock-wool cubes, they can then be transplanted into your hydroponics system.
