One of very few OMRI certified soil mixes out there. This is the exact soil that we use. A great blend of coco-coir, peat, moss and perlite. We grow everything we have with this being our base soil. With added mycorrhizae, it’s a great live soil to add to any mix! We recommend only using this soil mixed with one of our other available soils. Or, if used straight, a wetting agent is necessary. 2.8 cubic foot bag, loose fill.
