Canna Calmag Agent contains essential calcium and magnesium elements to increase the hardness of your water. If you live in a softwater area, or use reverse osmosis water treatments, the calcium and magnesium present in what would be called a normal water supply has been stripped away. Plants need calcium and magnesium for healthy development and blossoming flowers, so adding this to RO treated water or very soft water (below EC 0.4) will give you the gains of growing with 'normal' water (generally between EC 0.4 - 0.7).

  • Easy to use Calmag formula
  • Increases the EC range of your water supply
  • Aids nutrient uptake
  • Stimulates healthy plant development
