Description

Canna CalMag Agent 1 L – calcium and magnesium concentrate for buffering soft water

Canna CalMag Agent is a highly concentrated additive that replenishes calcium and magnesium in soft water and raises its EC to a level suitable for plants. This makes the water a better base for preparing nutrient solutions, helping plants grow strong and healthy.

Soft water – with an EC below 0.4 mS/cm – contains too little calcium and magnesium. Deficiencies of these elements also occur when applying low fertilizer doses, when transpiration is limited (for example under LED lighting), and when potassium levels are excessive. CalMag Agent helps prevent these deficiencies before they become visible on the leaves.

Add the product to the water first, then measure the standard doses of fertilizers and additives into the prepared base.

Key features

  • highly concentrated calcium and magnesium additive
  • designed for buffering soft water
  • prevents calcium and magnesium deficiencies
  • reduces premature leaf discoloration and drying of the leaf edges (so-called scorch)
  • supports healthy, vigorous growth and flowering
  • suitable for use with any type of growing medium

Application

CalMag Agent replenishes calcium and magnesium in water that contains too little of these elements – use it only with soft water (EC below 0.4 mS/cm) or reverse osmosis water. It works with every growing medium – soil, coco and hydroponics – for growing houseplants, garden plants and greenhouse plants. Water is classified by EC: below 0.4 mS/cm is soft water deficient in calcium and magnesium, 0.4–0.5 is water with a proper nutrient balance, and above 0.5 is hard water. The additive is not needed with water that has a proper nutrient balance or with hard water.

Directions for use

  1. Shake the bottle thoroughly before use.
  2. Fill the reservoir with water at a temperature of 20–22 °C.
  3. Add CalMag Agent at a rate of 0.1–0.5 ml per liter of water until the EC reaches 0.4 mS/cm.
  4. Add the standard recommended doses of fertilizers and additives to the prepared water.

The dose depends on the starting EC of the water – the lower it is, the more product is needed. An EC meter is essential for monitoring.

Safety and storage

Store the product only in its original, tightly closed bottle at a temperature of 10–30 °C. Protect it from high temperatures, frost and direct sunlight, and keep it out of the reach of children. The concentrate is not intended for consumption; avoid contact with skin and eyes.
