Rockwool/Stonewood In Hydroponics
While stone wool is relatively easy to set up and use, it does require some monitoring and irrigation adjustment to make the best of its ability to hold high levels of moisture and aeration at the same time. The main features of stone wool substrates is that they have little cation exchange capacity and they maintain their structure over a long period of time. In general, at field capacity, stone wool holds more water per unit volume than the other inorganic substrates and therefore has a greater buffering capacity. The larger reserves of a nutrient solution coupled with excellent drainage makes stone wool easier to handle as an inorganic substrate.
