Volcanic Rocks are rich in iron, magnesium, nitrogen and other minerals which are excellent for healthy succulents.
The jagged and irregular edges of Volcanic Rocks create gaps within the potting media which enhances air circulation, drainage and porosity.
Volcanic Rocks are a naturally quarried product, hence they may be slight variations in terms of the formation, size, colour or shape of the rocks.
 
Note: All 1 litre packs have been sifted before repacking into a clear ziplock bag.
