More than just calcium and magnesium

The secondary nutrients calcium and magnesium are among the most important additives in your plants' nutrient supply. But exactly what effect do these elements have on plant metabolism? How do they work? How can the effectiveness of calcium and magnesium be optimised? With Sensi Cal-Mag Xtra, Advanced Nutrients gives you a Cal-Mag agent that takes precise account of your plants? specific requirements, thereby guaranteeing optimum functioning.

Better understanding of plant metabolism

Advanced Nutrients have precisely analysed the processes of plant growth, in order to be able to probe more deeply into the specific requirements of your indoor crops. Magnesium, for example, is the key building block for producing chlorophyll, which means that it has a direct impact on the plants' ability to absorb available light. Calcium, by contrast, is indispensable as the basic building block for cells and cell growth. Nevertheless, calcium and magnesium are only two of many essential elements your plants need in order to exploit their potential to the full.

Taking Advanced Nutrients to the next level

In addition to magnesium and calcium, Sensi Cal-Mag Xtra has been consistently refined to include the important micronutrient iron plus a total of 20 L-form amino acids. Iron functions as a catalyst for key reactions during the course of plant development, principally and especially in connection with plant metabolism. Sensi Cal-Mag Xtra takes account of these special requirements and supplies iron in the form of necessary chelates and, most importantly, in the right balance with other nutrients. The result? All available nutrients become exponentially more effective and productive for your crops!

The Cal-Mag booster with a difference

Above all else, it's Advanced Nutrients' scientific approach that distinguishes Sensi Cal-Mag Xtra from conventional Cal-Mag additives. The right chelates in the right proportion, the improved supply of micronutrients and the 20 L-amino acids it contains ensure that all the nutrients can also really unleash their full potential.
