Details

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums. Growcubes are difficult to over-water if the container has good drainage. The Growcubes are a light weight alternative to your regular potting mix. You can use the Growcubes in any size pot and in many different growing systems
