Description Canna Rhizotonic is a powerful, algae based, vegetative stimulator for roots of fast-growing plants that already have roots or root initials. RHIZOTONIC is 100% natural, and contains multiple vitamins. RHIZOTONIC influences the root environment and is the ideal supplement for the crop environment created by the grower. RHIZOTONIC has a calming effect on plants, and is ideally suited for use when shipping or re-potting plants. RHIZOTONIC will also improve plants that are unhealthy or poorly developed. RHIZOTONIC can be used regardless of the type of medium. It is suitable for cultivation in potting mix and hydro culture. RHIZOTONIC is often sprayed on leaves and can be used as a simple means for raising the pH level in fertilizer tanks. Disclaimer from Canna: Canna Dates on back of bottles are Best Before Dates (Not Expiry) The dates on the CANNA products are not “expiry” dates they are Best Before Dates (BBD). Mineral nutrients are characteristically very stable when formulated correctly. When storage conditions are optimal, they will remain in perfect condition many years after manufacture and way beyond the BBD printed on the bottles. The dates we print on the bottle represent the extent to which we have tested, trialled and proven that the product will perform at its peak. It is the time period in which we guarantee it. It does not mean the product is degrading beyond that date, simply that we did not test it beyond that period.
