Burnt Rice Husk, otherwise known as Charcoal Rice Hull, is rich in silica and potassium and can be mixed with soil to provide more moisture and nutrient retention. It not only contributes nutrients but also absorbs odours and keeps the root system clean and hygienic. It is lightweight and also improves aeration and drainage when mixed into potting media.
Burnt Rice Husk can also be used as a carbon alternative.
Each bag is approx. 650g to 900g.
