This parboiled rice hill is a renewable resource that is a good alternative to perlite and vermiculite as well as being less dusty. Parboiled rice hulls have a pH near neutral to slightly alkaline. However, because of their low cation-exchange capacity, they have little effect of the substrate pH. Each 50 lb bag is about 7 cubic feet.
- Excellent drainage and moisture retention capacity.
- Will not tie up nitrogen.
- Free from weed seed
