Biobizz Calmag - organic calcium and magnesium Ca/Mg supplement for plants
Biobizz Calmag is a natural calcium and magnesium supplement designed for both professional growers and hobby cultivators. It helps supplement calcium (Ca) and magnesium (Mg), which are essential for proper plant growth and flowering.
Calcium and magnesium play an important role in processes such as cell production and photosynthesis. Deficiencies of these elements may occur especially when using very soft water or water purified by reverse osmosis (RO).
Biobizz Calmag allows Ca and Mg levels to be supplemented in an easy and controlled way. Its formula has been designed so it can be incorporated into an existing feeding programme without disrupting it.

- made using natural ingredients.
Calcium and magnesium - why are they important for plants?
Calcium (Ca) and magnesium (Mg) are essential elements required for proper plant development. They are involved in processes related to cell production and photosynthesis, making an adequate level of both elements important during both the growth and flowering stages.
The mineral content of tap water can vary considerably. This is especially important when using very soft water or RO water, which may contain low levels of calcium and magnesium. Biobizz Calmag helps supplement these elements in a controlled way.
How to use Biobizz Calmag
- Add the recommended dose of Biobizz Calmag to the water to supplement calcium and magnesium.
- Add the required Biobizz nutrients.
- Adjust the pH of the nutrient solution.
- Water the plants with the prepared solution.
When using RO water or very soft water, the manufacturer recommends using Calmag with every watering. If signs of Ca/Mg deficiency are observed, the product can be used once a week according to the appropriate corrective dosage.
