Substrate KIRYUZUNA small grain 2 L

Substrate KIRYUZUNA small grain (3-6 mm) 2L approx. This Japanese hard grain substrate is used to increase the drainage and the duration of the substrate in which we grow our bonsais. The hardness of its grain allows to make mixtures of substrates that maintain their structure for longer than if we grow in Akadama alone, which is very interesting to grow trees that are transplanted from time to time, such as conifers. Because of the size of the grains this substrate is used for bonsai of small size.
