XL Rhiza

XL Rhiza is a high-quality, peat-free substrate ideal for growers looking for a biologically active medium. Made from premium coco coir and enriched with beneficial rhizobacteria, it promotes vigorous root development, improved nutrient uptake, and enhanced plant resilience throughout both veg and flower stages. With a well-balanced texture, it offers exceptional moisture retention and aeration that helps prevent compaction and supports healthy oxygen flow throughout the root zone. It’s unbuffered and free from synthetic additives — meaning it gives growers a clean, living soil environment that supports long-term growth cycles, making it ideal for commercial operations and home grows dedicated to organic or biological cultivation methods. If you’re looking for a pre-fertilized option, XL FullMix is a nutrient-rich alternative. For growers that prefer a clean, neutral base without added rhizobacteria, XL Basic is a versatile option that gives you more control for customizing your medium.
