DetailsBecause the Styrofoam base floats, delicate roots stay above the water line making it suitable for seedling or cuttings. Super Starter Plugs are made of composted tree bark with a natural polymer that retains a perfect air to water ratio which maximizes water retention and nutrient exposure. Once the plants are rooted, the insert can be placed directly into an Ebb and Flow hydroponic system or be planted in soil.
