Small Rhiza

Small Rhiza is a compact, biologically active substrate created specifically to give young plants the healthiest start possible. Created with high-quality, peat-free coco coir that’s enriched with beneficial rhizobacteria, it provides strong root development, enhanced nutrient uptake, and early-stage plant resilience. Made with a fine texture that offers exceptional water retention, it’s ideal for seedlings, clones, and small containers — with the addition of active microbial life promoting a thriving root zone from the start. Unbuffered and free of synthetic additives, it gives you full control over feeding schedules, making it compatible with organic setups and precision grows. If you’re running a large-scale setup and want the same bioactive boost, XL Rhiza is a high-volume format of Small Rhiza. For growers that want to start with a clean, neutral base, Small Basic offers the same structure without added rhizobacteria.
