What Does Cal-mag Actually Do?
In the case of cal-mag supplements, calcium and magnesium are obviously the most important elements in the bottle. But do you know what calcium and magnesium actually do for your plant? How they operate? Do you know which ingredients help optimize the functioning of calcium and magnesium?
Many growers take this sort of information for granted. But plant science is rather complex, and a deeper understanding of these issues is critical to grow competitively. Magnesium is fundamental to chlorophyll, and is directly related to the process of absorbing light. Calcium is a basic building block of cells and growth. A deficiency of either means the most important growth reactions in your plant are stunted.
Obviously there’s more to the story. Plant metabolism is a very complex operation. But there is something most growers and hydroponic nutrient companies have overlooked when it comes to calcium and magnesium supplements, that is going to change the industry standard.
