Smart Approved WaterMark is managed by

Silica Earth's GrowSil Product is a granulated amorphous silica that has a water holding capacity to significantly increase water availability to plants in all soils. Increasing the plant available water content means less watering and nutrient application, as there is less leaching below the root zone. GrowSil also has a unique surface charge which means that applied nutrients are not locked-away and therefore they remain available to the plants.

GrowSil is completely reusable with no change in properties or performance overtime, and it is not manufactured or processed, so that it is environmentally sustainable with a low carbon footprint.
