Canna Calmag Agent Nutrients 1l, 5l, 10l Plant Food
CANNA CalMag Agent is a special concentrate for buffering soft water and can be used on all media.
Use CalMag Agent to increase the EC of your soft water. It will harden your water to make sure your plant can grow strong and healthy.
Advantages of CANNA CALMAG AGENT:
Increase in nutrient uptake
Stimulates better-quality flowers
Increases the EC of your water
Less nutrients required
Directions of use for buffering soft water :
Shake well before use
Add 0-1 ml per litre of water until you have reached an EC of 0.45mS/cm
Add your normal recommended nutrients and additives
Nitrogenous fluid fertiliser, containing Calcium and Magnesium
NPK – 6 – 0 – 0
Total nitrogen (N) 5.9%
Nitric nitrogen 5.1% (N-NO3)
Ureic nitrogen 0.8%
Calcium oxide (CaO) 6.8% (4.9% Ca)
Magnesium oxide (MgO) 2.4% (1.4%Mg)
What is the difference between soft/hard and/or bad water and what can you do about it?
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.
Bad water (EC>0.8) contains mainly sodium and chloride. These two elements block the uptake of nutrients and can even become toxic to your plants. With a reverse osmosis filter, you can remove both these elements. But making a mixture of R.O. water and bad water will not bring in enough calcium and magnesium, only bicarbonate to stabilise the pH. Make a mixture of R.O water with the bad water until you reach an EC of 0.2 and then add CANNA CALMAG Agent to this water until you reach an EC level of 0.4, or use 100% R.O. water in combination with CANNA CALMAG AGENT until you reach EC level 0.4
