Bulk Biochar - Fine (3 Sizes)

Bulk Fine Biochar Our Bulk Fine Biochar is a horticultural-grade, finely screened carbon amendment designed for retailers, growers, and plant professionals using biochar at scale. Made from upcycled woody materials sourced through local forestry and wildfire mitigation projects, this fine-grade biochar is ideal for top-dressing, soil blending, and improving the performance of existing potting mixes. Its ultra-porous structure increases nutrient retention, supports beneficial microbial life, and helps buffer moisture and mineral buildup — all while building long-term soil health. Fine Biochar is especially well-suited for houseplant care, greenhouse use, and custom soil blends where a smaller particle size is needed for even distribution and surface application. Key Benefits Improves nutrient retention and reduces leaching Supports beneficial microbes and healthy soil biology Buffers moisture and mineral buildup in container soils Helps reduce fungus gnat pressure when used as a top layer Stable, long-lasting carbon that remains active in the soil for years Ideal For Retail soil bars and refill stations Greenhouses and nurseries Terrariums Custom soil blending and potting operations Top-dressing houseplants and container gardens at scale Sustainability Our biochar is produced locally from excess forest biomass that would otherwise be burned or discarded — turning wildfire risk into a regenerative soil and climate solution.
