Visual Indicator: Akadama soil changes color (it darkens) when wet, indicating when to water your plant. Keep an eye that you don’t overwater them or don’t leave them under-watering, which retain their form when dry and absorb water when wet. Natural Material: This Bonsai Akadama (1/8 inch - 1/4 inch) is fired clay from 100% natural volcanic soil, eco-friendly, no additional fillers, no paint, no dyes, no chemicals, and provides the tree with moisture while preventing compaction. How to Use: Although akadama is one of the most commonly used mediums for bonsai soil, it’s rarely used on its own. Combining particles with different structural and water-retention properties allows for the creation of nearly limitless bonsai mixes.

It ticks off all the necessary requirements succulents needs for proper growth.
