Because of the low density of the Rockwool it provides exceptional capillary action for the roots, while retaining enough water for growth. Completely inert, cool right? Rockwool is ideal for Hydroponic growers. Rockwool will not buffer the pH of the solution nor degrade into soluble parts that could affect your plant. Rockwool must be prepared prior to use, and it is best to soak the cubes for 24 hours in a light nutrient solution that has been pH adjusted to 5.2-6.
