Why Athena?

Athena was born in the grow rooms of Los Angeles, California, in pursuit of what they call the perfect run. The line exists to support the modern grower at any scale, and it shows in how it’s built: short, honest feed programs instead of a shelf of single-purpose bottles, clean mineral ratios, and the same formulas running in home tents and licensed facilities. Whether you pour from a bottle or inject through a doser, there’s an Athena line built for how you already grow.

Born in the grow room

Formulated and tested by cultivators in Los Angeles before it ever ships — products built to improve quality, cut costs and drive consistency run to run.

Simple on purpose

Two-part base programs with carefully balanced mineral ratios. No twelve-bottle puzzle — Athena’s whole principle is making the complex simple.

Craft to commercial

Blended ready-to-use liquids for tents and craft rooms; Pro fully soluble dry fertilizer for facilities running Dosatron and Netaflex fertigation.

More than feed

IPM for pests and mildew, Cleanse for irrigation lines, and Reset with Perafoam for sanitation — the whole room covered by one brand.

How the lines run

Stage / job Run these What they do
Veg (Blended) Grow A + Grow B Two-part liquid base in equal amounts for vegetative growth and non-flowering plants.
Bloom (Blended) Bloom A + Bloom B · PK The two-part flower base; PK layers in mid-to-late flower as a low-nitrogen P/K booster.
Every stage (Pro) Core + Grow / Bloom · Balance Fully soluble dry program for fertigation systems like Dosatron and Netaflex; Balance sets pH up.
Peak flower Athena Proper 0-8-8 supplement that partially replaces base feed to push phosphorus and potassium, with fulvic and humic acids. Runs with either line.
Support CaMg · Stack Calcium/magnesium support, and a kelp foliar or drench applied weekly.
Pests & mildew IPM Contact control of soft-bodied insects and powdery mildew, seedling to harvest.
Lines & rooms Cleanse · Reset + Perafoam Cleanse descales irrigation and flushes; Reset and Perafoam sanitize hard surfaces between runs.

Anthony’s take: Athena is the line our commercial growers ask for by name — and the one we move by the tote. The Blended line is the easiest two-part we can hand a new grower, and the Pro line is what serious facilities run on dosers because it mixes clean and stays consistent batch to batch. Not sure which side of the line you belong on? Bring us your room size and your water source and we’ll spec it.
