Crystal Grain Indoor Plant Soilless Growing Medium, Fine Grain for Small Pots, Semi-Permanent, 100% Inorganic & Odorless, Visible Watering Indicator, Patented Japanese Tech, 3L (Resealable Bag)

[Beautiful and Clean Plant Substrate] La Terra Crystal Grain is a clean, sustainable, and elegant growing medium made from nutrient-infused mineral granules. Ideal for indoor use, these granules resemble decorative sand while providing essential nutrition. Nano-scale pores in each granule retain and gradually release vital nutrients, allowing for healthy growth without additional fertilizers. [Long-Lasting Nutrient Release with Natural 3-Phase Structure] Nutrients are released over 1 to 2 years through natural adsorption equilibrium, maintaining a root-friendly concentration (patented in Japan). The medium mimics natural soil's "three-phase structure": * Solid Phase: Sturdy granules for plant support. * Liquid Phase: Nutrient solution on granule surfaces. * Air Phase: Gaps between granules for essential root aeration. Maintains an ideal pH of 6.8-7.0. [Optimized Growing Environment] Unlike natural soils with unpredictable variables, Crystal Grain focuses only on essential components. By optimizing nutrient concentration, particle size, and air-water balance, it ensures a consistent, reliable environment. Simply add light and water for stress-free indoor gardening. [Minimize Unwanted Visitors] This 100% mineral substrate contains no organic matter, which typically attracts pests. Enjoy a clean, natural, and comfortable indoor gardening experience without unwanted visitors. [Reusable with a Special Regeneration Solution] The sturdy mineral structure resists breaking down into powder, ensuring durability for years. After a growth cycle, the medium can be refreshed using our dedicated "Regeneration Solution" (sold separately), making it both economical and environmentally friendly.
