Boost plant health with Canna Calmag Agent. Essential calcium magnesium supplement for soft/RO water. Prevents deficiencies, enhances nutrient uptake, stabilises pH. Ideal for coco, hydro, soil. Achieve vigorous growth and abundant yields.
Ensure optimal plant health and vigorous growth with Canna Calmag Agent, a concentrated calcium and magnesium supplement formulated to enhance water quality, especially for reverse osmosis or soft water. This essential additive provides the ideal ratio of calcium and magnesium, crucial secondary macronutrients that play vital roles in plant structure, chlorophyll production, and nutrient uptake. Fortify your nutrient solutions and prevent deficiencies with this high-quality product, designed to support thriving plants and abundant yields.
Key Benefits Of Using Canna Calmag Agent
- Prevents and corrects calcium (Ca) and magnesium (Mg) deficiencies, ensuring healthy plant development.
- Increases water hardness, particularly beneficial when using soft water or reverse osmosis (RO) water.
- Stabilises the pH of your nutrient solution over time, promoting consistent nutrient availability.
- Enhances the uptake of essential nutrients, leading to more efficient plant growth.
- Promotes stronger, healthier plants with improved resistance to stress and disease.
- Stimulates the development of better quality flowers and fruits.
- Highly concentrated formula, providing excellent value.
- Perfected for use with various growing media, including coco coir, hydroponics, and soil.
How to Use Canna Calmag Agent
- Shake the Canna Calmag Agent bottle well before use.
- Fill your nutrient reservoir with water at room temperature (ideally 20-22°C or 68-72°F).
- Measure the Electrical Conductivity (EC) of your base water. If the EC is below 0.4 mS/cm (milliSiemens per centimetre), supplementation with Canna Calmag Agent is recommended.
- Dosage: Add Canna Calmag Agent to the nutrient solution at a rate of 0.1 - 0.5 ml per litre of water until the desired EC is reached. The exact amount needed depends on the starting EC of your water. For reverse osmosis water, the typical dosage is around 0.2 - 0.4 ml per litre to achieve a base EC of 0.4 mS/cm.
- After achieving the desired EC with Canna Calmag Agent, add your base nutrients and other additives (such as Canna Coco A&B, Canna Boost Accelerator, Rhizotonic, Cannazym, and PK 13/14), mixing thoroughly after each addition.
- Adjust the pH of your nutrient solution as needed after all nutrients and additives have been added. Be cautious when using pH Up products, as Canna Calmag Agent can initially cause the pH to drop before gradually rising over 24-48 hours.
- Allow 24-48 hours for the nutrient solution to stabilise before making significant pH adjustments.
- For correcting existing deficiencies, use 0.1-0.5 ml per litre when watering or as a foliar spray.
CalMag supplements can be vital for coco growers, have a read of our blog post Soil vs Coco: What's the difference? to see why.
Available in 1 litre and 5 litres.
Frequently Asked Questions
Why do I need to use Canna Calmag Agent with RO water?
Reverse osmosis (RO) water has had most minerals removed, resulting in very low EC and no buffering capacity. Canna Calmag Agent replenishes essential calcium and magnesium, increasing the EC and stabilising the pH, which is crucial for proper nutrient uptake and preventing deficiencies in plants grown with RO water. Without Calmag, the pH of the nutrient solution can fluctuate wildly, and plants may struggle to absorb the necessary elements.Can I use Canna Calmag Agent with hard tap water?
If your tap water has a high EC (above 0.7 mS/cm), it already contains significant amounts of dissolved minerals, including calcium and magnesium. In this case, adding more Calmag Agent is generally not necessary and could even lead to nutrient imbalances or lockouts. It's best to test your water's EC first. If your water is very hard, some growers use an RO filter to reduce the mineral content and then use Canna Calmag Agent to bring it to the optimal level (around 0.2 - 0.4 ml/litre).Is Canna Calmag Agent only for coco coir?
While Canna Calmag Agent is particularly beneficial for coco coir cultivation due to coco's tendency to bind calcium and magnesium, it is suitable for all growing media, including hydroponics and soil, especially when using soft water or RO water as the base. It addresses the fundamental need for calcium and magnesium supplementation in water lacking these essential minerals.SKU: 1246Free delivery on orders over £60*
