Percentage volume ratio:
lava : kiryuzuna : kanuma - 20 : 40 : 40
pH 6

Kiryuzuna is a type of volcanic sand mined in Japan. It contains a large amount of iron oxide, thereby getting rid of chlorosis in plants. This soil has good breathability, porosity, water holding capacity and drainage. It is able to gradually give up nutrients and trace elements. On sale comes in the form of granules of different fractions from 1 to 6 mm. Does not decompose over time.
Does not tend to compact the soil and is very stable in structure, pH 6.5 - 6.8, root permeability is good, aeration is excellent.

Lava is a unique mineral of volcanic origin with high porosity. It contributes to excellent moisture and air exchange in the soil, is indispensable as a drainage. Due to its porosity is a source of macro - and microelements that promote the growth of the root system of plants. It contains iron, magnesium and calcium. Prevents the formation of mold, acidification and formation of lumps in the substrate. Excellent material for bonsai arrangements and growing mosses on the soil surface.

Kanuma is a fired clay produced in Japan. It is acidifying, so it is well suited for plants that prefer this type of soil, such as azaleas or rhododendrons. It has an acidic pH: 5.2 - 5.6. It has a high water-holding capacity and at the same time allows water to flow out quickly without flooding the roots. Required for quality watering water without chlorine and calcium, from which kanuma degrades.
