Calcium is essential for your plant's health. It fortifies the membranes of the cells and regulates nutrient use. Calcium has proven to be an invaluable aid to the plant vitality of various crops from tomatoes to watermelons! Additionally, calcium minimises the detrimental side effects of heat stress on your plants.

For plants to develop in good health, calcium and carbon are essential.  Calcium is usually obtained via the soil whereas carbon enters the plant as carbon dioxide which is necessary for the photosynthesis process.  CalCarb is a unique formula of a basic and common compound that is rich in both calcium and carbon.  

Calcium carbonate (CaCO3) is commonplace within agriculture for soil pH level adjustment whereas CalCarb is an unusual form of calcium carbonate. Calcarb is a highly unstable form which converts to calcium oxide (CaO) and carbon dioxide (CO2) rapidly upon application to the foliage. The CO2 levels directly outside and inside the stomata can rise threefold when using cal carb which is almost the optimum for photosynthesis efficiency.

Should your plant have been neglected, Calcarb can revive weakened plants by increasing photosynthesis and raising the surface pH of the damaged foliage which deters airborne pathogens from further attacks.
