Unlike traditional potting soil, this is a clean, soilless medium made from coconut fiber and pith. It is designed specifically for growers who want to manage their own nutrient inputs rather than relying on pre-mixed fertilizers.
The proprietary mix of fiber and pith is engineered to balance aeration and water retention. This combination encourages healthy root development by ensuring roots have access to both oxygen and consistent moisture.
