In response to popular demand, CANNA has produced a CALMAG AGENT. You can use this product to increase the EC of your soft water. It will harden your water to make sure your plant can grow strong and healthy.
• Fewer deficiencies
• Increase in nutrient uptake
• Stronger plants
•Stimulates better-quality flowers
• Increases the EC of your water
• Less nutrients required
Soft water has an EC level of below 0.4. With CANNA CALMAG AGENT you can raise your EC level to 0.4.
Normal water has an EC level between 0.4 and 0.7. It contains calcium, magnesium and bicarbonate to stabilise the pH. All CANNA products are designed to work best with this type of water.
Hard water (EC>0.8) contains more calcium and magnesium than the plant can handle. When you’re growing plants, the best way to treat this kind of water is to use a reverse osmosis filter and then mix your hard water with the R.O. water, until you reach an EC level of 0.4. Or, more easily, you can use 100% R.O. water and then use CANNA CALMAG AGENT to raise your EC level to 0.4.
You can also test the water yourself using an EC meter and 2 small tests based on colour indication. First, measure the EC to be sure it is not Soft or Normal water:
EC 0.0-0.3: the water is Soft
EC 0.4-0.7: the water is Normal
You can also ask your water supplier what type of water you have if you get stuck.
