Jack's Nutrients 15-0-0 Part B Calcium Nitrate — Water-Soluble Fertilizer for Calcium Uptake (2.2-lbs)

Overview

Jack's Nutrients 15-0-0 Part B Calcium Nitrate is a water-soluble powder designed for precise hydroponic feeding. It delivers calcium and nitrate nitrogen in a single product and is intended to be used with Jack's 5-12-26 Part A to support tailored nutrient programs. This pairing lets growers customize blends to fit crop needs while keeping a simple, flexible foundation for ongoing feeds.

With a focus on practicality and adaptability, the Part B formulation supports steady nutrient availability and predictable uptake in a variety of systems. The powder format travels well from mixing tank to reservoir, helping to reduce handling steps and waste while you scale feeds across your grow space.

What makes it work

• 15-0-0 analysis: provides a soluble calcium source and nitrate nitrogen, designed to work alongside Part A to customize your mix.
• Water-soluble powder: concentrated powder minimizes handling while maximizing feed coverage; simply dissolve and mix with water to feed multiple gallons.
• Mixing rate: dissolve 8.6 ounces in 100 gallons of water to achieve about 100 ppm nitrogen in the final solution.
• Continuous liquid feed program: designed for hydroponic systems; volume-based mixing instructions are included to help you scale feeds.
• Designed for simplicity: two major macronutrients by design, so you can add micronutrients separately based on plant needs.

How to use it

• Dissolve 8.6 ounces in 100 gallons of water to create a feed with approximately 100 ppm nitrogen.
• Incorporate this Part B solution into your reservoir as part of a continuous liquid feed program, pairing it with Part A as directed.
• Adjust micronutrient additions separately according to crop, growth stage, and monitoring results.

Real-world scenarios

Growers using hydroponic channels, ebb and flow, or drip systems can integrate Part B into their routine to support consistent calcium availability and nitrogen supply. The powder form travels well from mixing tank to reservoir, helping to minimize waste and storage space.

Why choose Part B with Part A

• Complementary nutrition: Part B supplies calcium nitrate while Part A can provide other major nutrients, enabling a broader range of customized mixes.
• Flow-friendly formulation: designed to dissolve readily and mix evenly in reservoir water, supporting uniform distribution in the system.

Note: This product is part of a broader nutrient lineup and is intended to work within your ongoing feeding program. Monitor plant response, adjust volumes, and consult the product guide for best practices.
