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. As well as stabilising your EC, CANNA CALMAG AGENT will also increase the uptake of nutrients, strengthen your plant, prevent deficiencies and also help develop better quality flowers.
