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, increases 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. It is suitable for cultivation in potting soil and hydroculture. Rhizotonic is often sprayed on leaves and can be used as simple means for raising the pH level in fertilizer tanks.
