Directions for Use: Please note that rockwool cubes will generally have a slighly alkaline pH. So, prior to using them, it's highly recommended that you pre-soak your rockwool cubes. This will help to give you the best results when it comes to your propagation. Use a small bucket or container, filled with water, and adjust the pH of the water to between 5.2 and 5.5. Next, place all of your rockwool cubes into the water and leave them to soak for between 12 and 24 hrs. This should help to stabilise your rockwool cubes to a pH of around 5.8 to 6.2. This is the ideal level recommended for hydroponic growing. Whenever you wet your rockwool cubes, make sure that the water you are using has a pH between 5.8 and 6.2
