Yes, you can use Oasis cubes to root cuttings. Oasis cubes are made from open-celled, water-absorbing foam. The foam uses capillary action to supply moisture to the roots. The cubes are inert and neutral, unlike rockwool, which pulls the pH up. It takes cuttings a little longer to root in the cubes, but they are easier to use than rockwool and less likely to have problems.
