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.
Advantages of Rockwool
- Excellent moisture retention
- Has good aeration allowing roots access to oxygen
- Light and very easy to work with
- Purchased in a ready to use fashion
- Does not degrade or breakdown over time
- Consistency and reliability
- Can be used from propagation to harvest.
Common uses of Rockwool in horticulture:
Growing from Seed and cuttings–Rockwool is fantastic as a germination medium. Seeds have access to optimal quatities of water and oxygen at all times.
Plug Production/Transplants–Rockwool remains the core growing medium of the plant, so that even if planted into bags or pots filled with LECA or coco peat, the rockwool must be left undamaged significantly reducing the stress of transplant.
