Shipping Information

Kanuma 2/5 mm (hard quality) is a fundamental component to create a well-aerated substrate suitable for carnivorous plants, providing a balance between moisture and air at the root level. It offers a slight mineral contribution and is more acidic than akadama, making it effective for cultivating certain carnivorous plants as it helps maintain a lower pH. The negative charges on its surface can sequester harmful cations for plants. Kanuma, a volcanic clay, is collected from depths exceeding 3 meters in Cryptomeria forests in Japan, while akadama is collected from shallower depths. Kanuma is collected, dried, heated to remove organisms and pests, and pulverized into different sizes. Kanuma can be mixed with pumice, volcanic lapillus, zeolite, and perlite to enrich the substrate with nutrients, or it can be used pure as the sole component of the soil.

For carnivorous plant cultivation, various mixes can be tested, for example:
– Pure (100%) for cultivating Nepenthes sp.
– Mixed with Akadama 30% / Lapillo 30% / Perlite 20% / Kanuma 20% for cultivating Nepenthes.
– Coconut Fiber 33% / Pumice 33% / Kanuma 33% with dry or live sphagnum around the collar for cultivating Nepenthes sp.
– Pure or in a mix with other mineral components (zeolite, tuff, lapillus, pumice) for cultivating Pinguicula sp.
