Akadama Ibaraki Triple Line Substrate (6–10 mm) 14 L

The Akadama Ibaraki Triple Line Substrate (6–10 mm) 14 L is one of the most prestigious and widely used substrates in the art of bonsai worldwide. Imported directly from Japan, this high-quality volcanic clay is carefully dried at high temperatures after extraction, ensuring hardness, durability, and long-term structural stability. It is then sieved to provide uniform particles between 6 and 10 mm, specifically designed for medium to large bonsai pots.

Thanks to its solid particle structure, this substrate offers optimal water and nutrient retention, releasing them gradually to the roots. This feature is essential to maintain the right balance between moisture and aeration, preventing waterlogging while allowing the root system to grow strong and healthy. Its porous composition also promotes excellent drainage and continuous oxygenation, which are crucial for the development of fine and vigorous roots.

With its neutral pH and high cation exchange capacity (CEC), Akadama improves nutrient absorption from irrigation water or fertilizers. As a result, bonsai trees become stronger, healthier, and more resistant, with better capacity to assimilate essential elements. This substrate can be used on its own or combined with other materials such as pumice, kiryuzuna, or volcanic gravel, allowing customized mixes for different bonsai species.

Considered for centuries the reference substrate in Japan, the Akadama Ibaraki Triple Line is the ultimate choice for bonsai enthusiasts and professionals alike. Its proven reliability, superior quality, and tradition make it the perfect base for cultivating balanced trees with well-structured roots and vigorous foliage. With this substrate, your bonsai will thrive in conditions that mimic the natural environment.
