Core

Athena Pro Core is a dry soluble calcium nitrate and micronutrient concentrate that forms the backbone of the Athena Pro Line system. It's the Part A equivalent in Athena's professional dry nutrient program — used in combination with either Pro Grow (vegetative phase) or Pro Bloom (flowering phase) depending on the stage of growth.

The core function of Core is to supply calcium in a form that remains stable as a concentrated stock solution while delivering consistent, reliable nutrition at scale. Calcium nitrate is the standard professional form of calcium delivery in hydroponic systems because it dissolves completely and stays in solution without precipitating. Micronutrients are included in the Core formula to ensure full-spectrum nutrition without needing additional chelated micronutrient supplements.

Ideal for mixing stock tanks and compatible with all automated dosing and injection systems. Core is particularly suited to commercial and large-scale cultivation operations where consistency, cost efficiency, and stock tank stability are critical. Made by Athena Ag, Los Angeles.
