[Exceptional Drainage]: The porosity of horticultural charcoal helps drain excess water, especially beneficial for containers without drainage holes, creating a keep fit environment for plant roots [Ideal Size for Plants]: The charcoal particles are 6-12mm in size.Granular bamboo charcoal has stronger activity and can keep the plants moist but not wet.Because made from renewable natural bamboo through high-temperature processing, bamboo charcoal comes in various sizes. A mixture of small to medium-sized particles can just make the soil more breathable, which is beneficial to the growth of plants [Efficient Nutrient Retention]: Its microporous structure absorbs and locks soil nutrients like a sponge, reducing loss from watering/rain. Nutrients release slowly as roots need them, supporting growth [purifiers Function]: Its dense micro-porous structure acts like a natural purifiers, effectively purifiersing impurities in the soil and water and purifying the soil environment. Through such purifiers and purification, the accumulation of impurities in the soil that are not conducive to plant growth, creating a cleaner growth environment for plant roots [Multi-scenario applicability]:These horticultural charcoal are suitable for various types of soil, including outdoor garden soil, succulent mixed soil, seedling cultivation soil, orchid pot mixed soil, indoor hanging plant soil, and many other types of soil.You can also crush into the appropriate size and use for small terrariums,seedling or hydroponic plants This gardening charcoal has a porous texture that promotes drainage and effectively avoids root damage in potted plants. Natural purifiers reduce impurities in the growth medium, firmly lock in soil nutrients, and minimize losses caused by watering or rain. It contains 6-12mm particles to avoid soil compaction and ensure the keep fit growth of plant roots
