About this item

• 【TRUSTED JAPAN QUALITY: 14,000+ SOLD】 Over 14,000 units sold in Japan last year. A 100% mineral-based substrate that keeps your indoor garden clean, elegant, and odor-free. Perfect for kitchen herbs and indoor vegetables.
• ✅ Long-Lasting Nutrient Release with Natural 3-Phase Structure : The nutrients are gradually released over 1 to 2 years through natural adsorption equilibrium, maintaining a root-friendly concentration over time (patented in Japan). The medium forms "three-phase structure" as same as natural soil.
• Around the roots, an "air phase" is created where air flows through the gaps between the granules. On the granule surfaces, there is a "liquid phase" containing nutrient solution, and the granules themselves form the "solid phase" that supports the plant. The pH is maintained at 6.8-7.0.
• ✅ Optimized Growing Environment : Unlike natural soils that contain tens of thousands of variables—including elements that may hinder plant growth—Crystal Grain focuses on only the essential components required for healthy plants. By eliminating unnecessary factors and optimizing key soil parameters such as nutrient concentration, particle size, and air-water balance, it provides a consistent and reliable growing environment. Simply add light and water for stress-free indoor gardening.
• ✅ Minimize Unwanted Visitors : This substrate contains no organic components, that typically attract unwanted visitors, making it a great choice for clean and comfortable indoor plant care. You can enjoy a clean and natural growing experience.
