Canna Rhizotonic

By CANNA     9 December 2021 

CANNA RHIZOTONIC is a powerful, algae based, vegetative stimulator for plant roots. It contains multiple vitamins and is 100% natural. RHIZOTONIC adds more than 60 microbiological substances that considerably speed up the growth of a balanced root environment.


Stimulates new root growth on cuttings and transplants.
Besides stimulating root growth on plants that are already rooted, RHIZOTONIC also stimulates new root growth on cuttings and transplants. The various trace elements and vitamins such as B1&B2 stimulate the production of hormones and root growth, thus providing beautiful, strong white roots.
Speeds up the germination process when used to soak seeds prior to planting.
If you dilute RHIZOTONIC (40ml/10 litre), you can use it to soak seeds. RHIZOTONIC softens up the seed skin, making it easier for the seed to burst and germinate.

Enhances overall plant growth and chemical reactions in the plant to ensure a healthier, powerful and stronger plant.
Good results start with a healthy plant. Because RHIZOTONIC stimulates root growth, it improves the strength of a plant. This is especially important during the first weeks of a plant's life, since young plants are the most vulnerable. RHIZOTONIC stimulates further root development, increases the plant’s resistance to diseases and promotes its inner and outer strength.

Aids in the recovery process of any plant or cutting that has been subjected to stress in any way whatsoever.
Many growers agree that plants recover much quicker from stress situations if the leaves have been sprayed with RHIZOTONIC. Such stress situations could for example occur during transport and re-potting plants. RHIZOTONIC will also improve plants that are unhealthy or poorly developed.
Furthermore, RHIZOTONIC is often sprayed on leaves and can be used as a simple means for raising the pH level in fertiliser tanks.
RHIZOTONIC can be used regardless of the type of medium. It is suitable for cultivation in potting mix and hydro culture. You can use it during the whole growth cycle. From seed to harvest!

Correcting the pH value.

If the acidity in the root environment is between 5 and 6.4 then the pH of your growing environment is OK and you do not have to take any corrective measures. Try to avoid correcting the pH unless it is really necessary. It’s more likely to do harm than good; the plant likes its peace and quiet. It is more important to monitor how the acidity changes over a longer period. If the value falls below pH 5 or rises above pH 6.4 then it is advisable to gradually start making adjustments. 

Correcting the acidity is most easily done by lowering the acidity of the feeding solution with nitric acid during the growing phase and phosphoric acid during the flowering phase or, as the case may be, to raise it with caustic potash, potassium bicarbonate or soda[8] and CANNA RHIZOTONIC. Ensure that the pH in the solution that is used does not fall too far below 5.0. When growing in rock wool the fibres will be harmed causing a lot of alkaline material to be released at very low pH values. In addition, the pH is more difficult to control due to the absence of bicarbonate.

A high pH in the root environment can also be caused by bicarbonate that has built up. To remedy this maintain 20% drainage or rinse through with a more acid solution.


Oligosaccharides are natural carbon compounds with a regulating function in the growth of all plants. They were discovered not so long ago and the number of functions attributed to these substances is still growing. Besides their regulating function for growing and blooming plants, oligosaccharides increase the plant’s resistance to harmful fungi and bacteria. Oligosaccharides activate the production of natural antibiotics that the plant uses to fight pathogens (organisms that cause disease or illness to the host). Besides all this, oligosaccharides stimulate the growth of the plant above ground as well as its roots. CANNA RHIZOTONIC is rich in oligosaccharides. Everyone who has worked with this renowned product knows its power to stimulate growth.

100% vegetable growing stimulator.

To get your grow off to a flying start why not give your plants some tonic? CANNA RHIZOTONIC is a powerful, vegetable based root stimulator. It causes extra root growth and in this way helps the plants to establish themselves more quickly.

For this reason RHIZOTONIC is an ideal product for cuttings and plants that have to be potted or for plants that have developed poorly after being in a state of shock. As well as this RHIZOTONIC contains a wide variety of trace elements that are advantageous for the plants. The tonic is easy to apply and you don’t need very much at a time. 

What is foliar feeding and why should I do it?

Foliar feeding is the technique of applying a liquid fertiliser directly to the leaves of plants where the nutrients are taken into the plant leaves through the stomata and epidermis. The benefit of foliar feeding is the nutrient can be absorbed directly into the plant where growth is occurring. The plant reacts quicker than feeding through the roots, which aids in stress recovery It is best to apply during the beginning or end of the daytime period when the environment is not too hot (around 24ºC is ideal). The nutrients used must be in a form that is readily available to the plants.

The first 2 or 3 times that you use RHIZOTONIC we recommend you to add it to the feeding water in the ratio of 1:250 or spray it on the leaves.

Direction of use

User Instructions

  • Shake bottle well before use
  • Dissolve 40 ml concentrate per 10 litre of water (1:250)
  • Spray the cultivation medium 1-6 times daily. Spray directly on the leaves until a strong root system has developed
  • When re-potting, one should pre-treat the growing medium with this solution
  • Set the pH of the nutrient reservoir after adding RHIZOTONIC as it will slightly increase the pH

Storage, health & safety and other directions
