How can rock wool be effectively used in hydroponics systems to promote plant growth and nutrient absorption?

Rock wool can be effectively used in hydroponics systems to promote plant growth and nutrient absorption by providing a stable and well-draining medium for plant roots to grow in. The fibrous structure of rock wool allows for good aeration and water retention, which helps roots access oxygen and nutrients more easily. Additionally, rock wool can be easily shaped and manipulated to support plant roots and encourage healthy growth.
