Plagron Calmag Pro - Increases Calcium & Magnesium Levels in Soft Water Areas Calcium and Magnesium are extremely important secondary macronutrients. Soft water areas have lower le vels of these key nutrients, so in some instances it's important to supplement with them, and Plagron Calmag Pro is perfect for the job. Calmag is also useful for growers running reverse osmosis units and for treating deficiencies. Calcium Calcium is especially important during the vegetative growth stages. Like silicon, it helps to strengthen cell walls, which promotes vigorous growth and more robust structures. Calcium is vital for transporting nutrients around the plant. Magnesium Magnesium is a vital component in the formation of the chlorophyll molecule. Chlorophyll is responsible for giving plants their green colour and it is used in the process of photosynthesis, where plants take energy from your grow light and use it to split CO2 into carbon and oxygen. The carbon is then used by the plant and the oxygen is released as a waste product. Visit the Plagron Nutrients category to see the complete range. Show more
