Calcium

Calcium is a fundamental building block in cell formation and particularly in cell physiology. It is the fifth most abundant element in the Earth's crust. Vitamin D in need for absorbtion.

Lime: Calcium oxide is a white crystalline solid with a melting point of 2572°C. It is manufactured by heating limestone, coral, sea shells, or chalk, which are mainly CaCO3, to drive off carbon dioxide. Lime raises pH and limits the microbial populations within a medium.

Calcium chloride: is a chemical compound of calcium and chlorine. It is highly soluble in water and it is deliquescent. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers. Chloride ions interfere with uptake of other negatively charged fertilizer ions and also limits the microbial population within a medium..

Calcium sulfate: is used in Gorilla Grow Complete as calcium source and for sulfur nutrition. Sulfate is the form that most microorganisms and plants use as source of sulfur for nutrition. Sulfate and sulfite is present in only a few unusual constituents of cells. Microbes and plants obtain their sulfur by reducing sulfate to sulfide which is used to synthesize almost all their sulfur containing components. Calcium sulfate is finely ground and suspended in water for distribution within the production system, where it is processed by the microbial population in the media before the calcium is released into the media in a plant-available form.
