Calcium Nitrate

Description

Calcium Nitrate is a hydroponic nutrient high in nitrogen and calcium. It is incredibly important to plants, sometimes called the 4th biggest cation. Calcium makes up cell walls and membranes protecting from disease. Calcium also gives plants their rigidity and resistance to pests. Without calcium, plants will be weak and unable to support their fruits and flowers. Calcium also aids in nutrient uptake.

Always add calcium products to hydroponic solutions first. In solution the calcium ion is positively charged. This means it will readily bond with other ions that are negatively charged. Once bonded, these nutrients are unavailable to plants. By adding calcium and chelators like fulvic acids first will help prevent bonding of these ions.

Calcium Nitrate Registered Analysis:

• Nitrogen (N): 15.5%
• Nitrate-Nitrogen (N-NO3): 14.4%
• Ammoniacal Nitrogen (N-NH4): 1.1%
• Calcium Oxide (CaO): 26.5%
• Calcium (Ca): 19.0%

Silica and calcium can sometimes cause problems with each other when used together. In the worst case, a struvite precipitate can form. This struvite is not available to plants as nutrients. Add silica products to nutrient solutions before adding calcium. Dissolve calcium nitrate in a smaller container before adding to your solution when also using silica. Stir as you pour.

Preparing Stock Solution – 1kg Calcium Nitrate = 4L Stock Solution

• Fill a 5L container with 3L water.
• Add 1kg Calcium Nitrate to the container of water stirring until all is dissolved.
• Once dissolved, top container up with water to reach 4L of solution.
• Store container closed tightly and out of direct sunlight.
• 4ml Stock Solution = 1g Dry Calcium Nitrate
