Jack's Classic Calcium Nitrate

No, this is not a complete fertilizer. It is designed specifically as a Part B component to be used alongside a Part A fertilizer, such as Jack's 5-12-26, to provide a balanced nutrient profile for your plants.

Separating the components prevents nutrient lockout and precipitation, which can happen when concentrated calcium and sulfates are mixed together in a single container. Using a two-part system ensures that all nutrients remain fully soluble and available for your plants to absorb.

While it is formulated specifically for continuous liquid feed programs in hydroponic systems, it can be used in soil-based gardening as well. Just ensure you are following the appropriate dilution rates for your specific crop and growing medium.

Because it is highly soluble, it mixes easily into water. However, you should always dissolve the Part A and Part B components separately in water before combining them in your reservoir to ensure proper mixing and prevent any potential chemical reactions.

This product provides a highly available source of nitrate nitrogen and calcium, which are critical for strong cell wall development and vigorous leaf growth. It allows you to precisely manage your nitrogen levels without adding excess phosphorus or potassium.
