Jack's Nutrients Cal Nit Part B 15-0-0 - 1 kg

Jack's Nutrients Cal Nit Part B 15-0-0 is a water-soluble calcium and nitrogen fertilizer component made to support calcium uptake and strong leaf growth in two-part nutrient system programs. It’s a targeted calcium nitrate style nutrient designed for growers who want a clean, dependable calcium source alongside nitrate nitrogen for steady green growth.

This Part B formula is described as a very soluble and available source of calcium, built around very pure, completely available nutrient sources. That matters when you’re aiming for consistent plant performance, because calcium uptake supports new tissue quality and helps plants maintain stronger, more resilient growth. When calcium availability is a priority, this product keeps the focus on the essentials without extra additives or complicated positioning.

Jack's Nutrients Cal Nit Part B 15-0-0 is centered on calcium plus nitrogen, with nitrogen present in nitrate nitrogen and ammoniacal nitrogen forms. The balanced nitrogen forms support active growth while keeping the role of calcium clear and direct. For growers managing leafy, fast-growing plants, the “calcium uptake” and “strong leaf growth” focus aligns with the kinds of outcomes you look for when dialing in overall plant vigor.

As a Part B in a two-part nutrient system, this product is meant to be used as a foundational component in structured nutrient programs where calcium is supplied separately from other core elements. The formula’s “pure combination of calcium and nitrogen” positioning is a practical differentiator: it’s designed to give flexibility within a two-part approach while staying straightforward and predictable as a calcium-and-nitrogen source.

The facts are simple and useful: the NPK is 15-0-0, and the inputs are derived from ammonium calcium nitrate double salt. Those details reinforce what this product is built to deliver—available calcium and nitrogen in a highly soluble format—without turning it into an all-in-one fertilizer.

Jack's Nutrients Cal Nit Part B 15-0-0 is a good fit for growers who want a very soluble calcium source for two-part nutrient system setups, especially when calcium uptake and strong leaf growth are the priorities in an active growth cycle.
