Discover the Calmag agent which will allow you to increase the Calcium and Magnesium content of your fresh water. This will have the effect of changing it into normal water, which is much better for the health of your plants.
What is the difference between soft water and hard water?
So-called soft water has an EC level (Electro Conductivity, estimate of the richness in nutrient salts present in the form of ions in the nutrient solution.) of less than 0.4.
Normal water has an EC level between 0.4 and 0.7, it contains calcium and magnesium (calmag) as well as bicarbonate to stabilize the pH.
Hard water has an EC level above 0.8. It contains more calcium and magnesium than the plant can handle. When growing plants, the best way to deal with this type of water is to use a reverse osmosis filter, then mix your hard water with the osmosis water, until you reach an EC level of 0.4. Or, more easily, you can use 100% reverse osmosis water and then use CANNA CALMAG AGENT to increase your EC level to 0.4.
To know the EC level of your water, do not hesitate to use an EC meter
