Growing Plants in Coco Coir ... you may may find that coir does not work as well for acid-loving plants, such as azaleas and blueberries. Coir can also be far more user-friendly than peat moss or rockwool.
Coco-peat fiber facilitate excellent lateral water distribution for the benefit of berry roots.
Rockwool is a volcanic rock heated to extreme temperatures to fluff it out and it has been used in hydroponic systems for many years and is extremely popular with some growers as they feel it is the best media, but has many drawbacks; Not environmentally friendly and hard to dispose of.
Dust and fiber are a health risk.
pH is naturally high which requires adjustment by the grower.
