It is amazing. Plants grown in combination with an appropriate fertilizer even without soil in this clay granules (tried with various herbs, peppers, chillies and even tomatoes). This is the care, breeding and repotting of houseplants easier and cleaner than ever. In addition, also pests feel less comfortable in the granules than in soil. Only criticism: After some time, being built on the granules a white layer. Probably a mixture of fertilizer and lime from the irrigation water. Otherwise, however, a top product for indoor plants.
