A healthy plant starts with a healthy root system, and healthy root systems start with K-L-N Rooting Concentrate. K-L-N is a vitamin-hormone and nutrient solution proven to promote vigorous root development on cuttings, transplants and newly potted plants. In addition to vitamin B1, K-L-N contains both IBA and IAA rooting hormones to kick your plant's root growth into high gear. K-L-N makes propagating cuttings incredibly simple. K-L-N is also perfect for use throughout the plant's life to promote new root growth and reduce transplant shock when repotting.
