Eco-Grodan-Stonewool-blocks
Basalt originates from the earth's interior and was brought to the surface as lava many thousands of years ago. Melted again, the material in its basic form is made by spinning it into a defined structure. When this has cooled down, it is compressed into stonewool as we know it.

From volcanic basalt to stonewool it is a completely natural process producing a natural final product: inert and free of pathogens.

Properties
Stonewool is used more and more, because of the following properties:

  • it is man-made material, manufactured to accurate specifications;
  • it is inert and pathogen-free
  • it is easy to manage
  • it produces a higher yield
  • it is more controllable than other substrates
  • it is more efficient with water and energy use
  • it minimizes the use of desinfectants
  • it minimizes nutrient use
  • good air to water ratio
  • the AO 36/40 (1.5") starter blocks fit well in the hole size provided in the blocks below
