Very porous, it can store up to 40% of its weight in water. It doesn't fall apart. Contains potassium, magnesium, calcium and iron. Neutral pH, helps maintain the pH of its neutral environment thanks to its buffering effect

Kyriu

Rich in iron, recommended for slow-growing bonsais because it does not disintegrate easily and lasts several years. No absorption. Slightly acidic pH: 6.5 To be used combined with akadama for Bonsai

Kanuma

Due to its light, well-drained and acidic nature, Kanuma is ideal for creating a favorable growing environment for the delicate roots of Bonsai Trees. Acidifies soil, good for growing Bonsai trees and other acid-loving plants. pH between 4.5 and 5.5

Akadama Iwamoto

Holds water and nutrients well for sensitive bonsai roots. Cooked, therefore harder and degrades less quickly, beige. Neutral to slightly acidic pH between 6.5 and 6.8
