The Hawita-Fruhstorfer aquatic plant soil is a ready-to-use growing medium for use in in-house garden ponds and other water areas in the open air. The nutrient content and pH value are specially tailored to the requirements of aquatic plants. This provides the plants with a sufficient supply of nutrients and at the same time prevents high nutrient input into the water. The quartz sand ensures a high level of stability for the plants and prevents the earth from floating up.
