Rockwool substrates are a type of growing medium used in hydroponic and aquaponic systems. They are made from spun basalt rock and chalk, which are heated and spun into fibers. The fibers are then compressed into blocks or cubes, which are then used as a growing medium for plants.

Rockwool substrates are an ideal growing medium for hydroponic and aquaponic systems because they are lightweight, sterile, and provide excellent drainage and aeration. They also have a high water-holding capacity, which helps to keep the roots of the plants moist and healthy. Additionally, rockwool substrates are pH neutral, meaning they won’t affect the pH of the nutrient solution.

Rockwool substrates are often used for planting vegetables, herbs, and flowers. They are also used for propagating cuttings and seedlings. The rockwool cubes provide a sterile environment for the roots to grow in, and the high water-holding capacity helps to keep the roots moist. Additionally, the rockwool cubes provide excellent drainage and aeration, which helps to prevent root rot and other diseases.
