About This

• ✅ Beautiful and Clean Plant Substrate : La Terra Crystal Grain is a clean, sustainable, and visually elegant plant-growing medium made from nutrient-infused natural mineral granules. Designed for indoor use, the granules resemble decorative topdressing sand while providing essential nutrients. Each granule contains nano-scale pores that retain and release gradually nutrients vital for plant growth, allowing you to use it without the additional fertilizers.
• ✅ 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.
• ✅ Reusable with a Special Regeneration Solution : The mineral granules have a sturdy molecular structure that resists breaking down into powder, allowing for use over many years. After a growth cycle or when transplanting, the medium can be refreshed using our dedicated “Regeneration solution” (sold separately), making it both economical and environmentally friendly.

• ≪How to Use≫
• 1. When repotting store-bought houseplants, check for any visible debris or contamination on the leaves and remove them. 2. To clean off mud and insects from the roots, soak the root area gently in a bucket of water. 3. Fill the bottom 1/4 of the pot with Crystal Grain. Place the plant, then fill in around it with more Crystal Grain. 4. After planting, water thoroughly.
