Roots Organics Lush growing mix is an amended peat-based media that delivers absolute consistency and control. Nutrient-rich, this robust mix combines a well-measured primary fertility package with ideal foundational components to maximize yield in mature flowering plants. The precise ratio of peat, coir, perlite, pumice and worm castings has been added to create ideal water holding capacity and drainage. Rich in sustaining nutrients, this media is designed for a water-only or reduced nutrient schedule. In fact, most plants can happily feed on Lush for up to eight weeks without additional support.
