House & Garden Top Booster is an excellent flower stimulator which works on the basis of potassium, phosphorous and EDDHA-Fe (Iron). These elements are essential for the plant's flowering phase. Potassium is used for the beginning of flowering. Phosphorous stimulates the growth of the fruits, while EDDHA-Fe ensures a better coloring of the leaves. Top Booster creates an optical drought giving the plant the impression that the last phase of it's life cycle has started. To ensure it's survival, the plant will start to form flowers and fruits so that it can reproduce itself. After three or four days, the ususal nutrient feeding schedule should be resumed. With this early triggering, the plant will continue to form flowers and fruits.
