Athena Pro Core

What It Is

Athena Pro Core is the backbone of the Athena Pro Line — the one component that stays in the feed at a consistent rate from propagation through the end of flower. Where Pro Grow and Pro Bloom rotate in and out by growth stage, Core is always present, supplying the steady calcium-nitrogen demand that high-rate indoor production places on a crop every single day.

The formula is built on calcium nitrate as its primary salt, with a full chelated microelement package — iron (EDTA), manganese (EDTA), copper (EDTA), zinc (EDTA), boron (boric acid), and molybdenum (sodium molybdate) — coated evenly into each granule so the micro fraction stays homogenous through the bag. The result is a 14-0-0 dry concentrate that mixes cleanly into stock solution, holds stable in a reservoir, and leaves no sediment in lines or injectors.

Who It's Built For

Pro Core is designed for commercial-scale licensed cannabis and hemp operators running automated fertigation: Dosatron injection, Netaflex, Rhythm, or any proportional dosing system. The dry-salt stock-tank approach — mix a concentrated liquid first, then let the injector meter it into the feed line — is exactly how high-throughput facilities cut nutrient cost per gallon without sacrificing formula precision.

It is equally at home in rockwool-slab systems, deep-water culture, and inert-media coco or perlite builds. Athena discourages adding dry powder directly to a batch reservoir in small amounts; instead, the protocol is to dissolve into a stock concentrate (up to 2.5 lb per gallon of water) and inject from there — a workflow that maps cleanly onto most commercial room layouts. Operators replacing a multi-bottle liquid program will find that Pro Core, paired with Pro Grow or Pro Bloom on the same feed schedule, covers the baseline nutrition that typically required three to five separate liquid products.

Key Features

100% water solubility at room temperature — no heating, no pre-dissolving in hot water, no sediment accumulating in reservoir bottoms or filter housings. The large-grind granule format is engineered specifically to dissolve completely, which is non-trivial in a commercial facility running thousands of gallons of feed water per week.

Low heavy-metal content puts Pro Core in compliance-friendly territory for licensed operators in regulated markets where residual heavy metals in final product are tested. The chelated microelement delivery — EDTA and DTPA chelation on iron, manganese, zinc, and copper — keeps those trace elements plant-available across a broad pH range rather than precipitating out at the edges of the working window.

Pairing ratio on Athena's published feed schedule: 0.6 g of Pro Core per 1 g of Pro Grow or Pro Bloom. Always measure by weight, not volume. Do not combine dry concentrates together before dissolving separately into water first.

How It Fits a Commercial Build

Pro Core anchors a three-product dry-salt program — Core runs constant, Grow covers vegetative, Bloom covers flower — replacing the five-to-ten-bottle liquid programs that many facilities inherited from smaller-scale operations. The dry format dramatically reduces freight weight and storage footprint compared to equivalent liquid volumes, which matters when you are ordering at scale for a multi-room facility.

For operations scaling into commercial production or transitioning from a liquid program, the Athena Pro Line feed schedule and dosing app give a documented, community-validated starting point. Pro Core's role in that schedule is fixed: it is not adjusted up in veg and down in flower the way Grow and Bloom are — it runs at a steady EC contribution throughout, which simplifies programming of injector ratios and reduces the number of recipe changes a head grower manages across a full 13-week run.
