Canna Rhizotonic is a powerful, algae based, vegetable stimulator for roots of fast-growing plants that already have roots. Rhizotonic stimulates the further root development, increasing the plant's resistance to disease and promotes its inner and outer strength. Rhizotonic is 100% natural, and contains multiple vitamins. Rhizotonic influences the root environment and is the ideal supplement for the plant environment created by the grower. Rhizotonic has a calming effect on plants, and is ideally suited for use when shipping or re-potting plants as well as to improving plants that are unhealthy or poorly developed. Rhizotonic can be used regardless of the type of medium.
