Our premium biochar is one of the few OMRI-listed options out there—made from 100% sustainably sourced hardwood and crafted through clean pyrolysis for unmatched purity. It’s ultra-porous and packed with carbon to give your soil blends—and your plants—a serious boost. With over 80% organic carbon, our biochar goes well beyond the International Biochar Initiative’s Class One standard (which starts at 60%). That means it stays stable in your soil longer, holds nutrients better, and helps beneficial microbes thrive. Plus, it can hold up to six times its weight in water, keeping your plants hydrated and strong. ✅ OMRI-listed for organic growing ✅ Supports strong roots and soil structure ✅ Packed with over 80% stable organic carbon Proudly packaged with care by our small, family-run team in sunny San Diego.
