If you live in a soft water area, then you should be using the newly released CalMag Agent by Canna. Developed due to popular demand, CalMag Agent helps to harden soft water, by introducing additional levels of Calcium and Magnesium to your nutrient solution.

Soft water, generally speaking, has an EC reading of approximately 0.2, the optimum level for strong and healthy plant growth is between 0.4 to 0.7. By using Canna CalMag Agent, it will not only add much needed calcium and magnesium, it will also raise the EC to the required level.

By using Canna CalMag Agent, along with increasing the EC, the plants nutrient absorption will be improved and deficiencies will decrease, resulting in stronger, healthier plants with enhanced fruit and flower production.

Canna CalMag Agent can also be used in hard water areas with an EC reading of greater than 0.8, but Canna advise that a Reverse Osmosis (RO) filter should be used to initially reduce the EC, then CalMag Agent is added until the EC reaches the required 0.4.-0.7.


  • Helps to stabilise EC levels in soft water regions
  • Provides additional levels of Calcium & Magnesium
  • Promotes healthier and stronger plant growth
  • Improves fruit and flower production
  • Can be used in hard water regions when using Reverse Osmosis (RO)

Canna CalMag Agent is also a highly concentrated formula, so just 1ml per litre of water is all that’s needed to make a difference to the health, growth and flower production of your plants.
