Rock Wool Hydroponics

Rock wool hydroponics is a type of hydroponic system that uses rock wool as a growing medium. 

Rock wool is a type of mineral wool made from volcanic rock that has been heated and spun into fibers. 

It is commonly used in hydroponic systems because it is sterile, pH neutral, and has good water retention and drainage properties. 

In a rock wool hydroponic system, plants are grown in small cubes or slabs of rock wool, which are placed in a tray or container. Nutrient-rich water is then circulated through the rock wool, providing the plants with the necessary nutrients for growth. This type of hydroponic system is popular for growing a variety of crops, including lettuce, herbs, and strawberries.
