Marisse Eco-Natural is a value-focused growing medium made from clean coco material, ideal for growers who prefer to manage substrate treatment themselves. With a mixed structure and an Air-Filled Porosity (AFP) of 23.5%, it provides balanced aeration and water retention suitable for a variety of crops. Best suited for nurseries, vegetables, and flowers grown in greenhouses or semi-controlled environments, this substrate allows flexibility for growers to pre-wash and buffer according to their specific fertigation needs.
