This is mostly uniform in shape and is about 1/32" when sifted, so most of the rocks are between 1/32" and 1/8". It is like coarse sand, and too small to put in a soil mix, such as pon.
This horticultural-grade black lava -
- Improves soil drainage
- Can be used as a top dressing
- Does not break down nor decolorize easily.
PLEASE NOTE:
This product may contain a small amount of debris, which is normal. During transportation, friction and pressure can occur, sometimes causing minor powdering. Thank you for your understanding
