The use of stone wool substrate offers many advantages. Thanks to the controlled manufacturing process, this growth medium is of a consistently high quality. The sterile production under extreme temperature ensures that the product is clean and sterile. Its unique hydrophilic fibre also makes the cultivation on stone wool substrate very easy to control. The grower can administer the amount of water and nutrients the crops need in a very directed and controlled manner, to achieve optimal growing results. Waste becomes a thing of the past. Efficient use of water and nutrients keeps yield per square metre high, and energy consumption per unit of product low. Additionally, the product is lightweight, making it easy to use. And last but not least, stone wool can be easily re-used. To sum up, it is a sustainable and environmentally-friendly product.
