About This Improves Soil Health: Mix Horticultural Charcoal with soil to improve soil health and structure. Those small to medium size pieces keep soil from compacting on roots of potted plants. 1-Quart Bag: 8-15mm charcoal is a better option for indoor plants compared to hardwood charcoal due to its more porous structure, higher adsorption capacity, renewable resource, and environmentally friendly production process. Neutralizes Toxins: The high adsorption capacity of the charcoal helps to remove impurities, toxins, and odors from soil and water, creating a healthier growing environment for plants. Regulates Moisture Levels: The charcoal helps to regulate moisture levels in soil, preventing soil from becoming too wet or too dry, which can be harmful to plants. Improves Soil Aeration: The porous structure of the charcoal improves soil aeration, allowing for better air and water flow. This can lead to better root development and improved plant growth.
