When developing a nutrient program for hydroponics and fertigation, I always start with fulfilling my calcium requirement with calcium nitrate as the first step in calculating the fertilizer inputs needed to build the complete solution. This is why calcium nitrate is the core, base component in any water-soluble fertilizer program. It provides all or almost all of the calcium required, and a very large portion of the nitrogen needed for most horticultural crops grown in controlled environments. Calcium nitrate is completely soluble in water and has a high maximum solubility. This makes it ideal for making concentrated stock solutions for inline injection into fertigation and hydroponic solutions.
