Athena Nutrients
Athena is a Los Angeles nutrient company built around one idea: make feeding simple enough that the result comes down to the grower, not the guesswork. It's also the nutrient line AC Infinity offers as the add-on to its own grow kits in the US — so if you're running an AC Infinity tent, this is the system designed to sit alongside it. Quick Bloom Lights stocks both Athena lines in Sydney, from a first 0.9 L bottle through to commercial 18.9 L drums and 11.3 kg boxes.

Why growers switch to Athena
Most nutrient ranges grow by adding bottles. Athena went the other way. Both lines are mineral-only formulas with a small number of parts, published feed charts, and nothing that needs shaking, brewing or mixing in a special order. Every product is fully soluble, so it won't settle in a reservoir or clog drippers, venturis or peristaltic dosers.
The payoff is consistency. With fewer variables in the bucket, when something changes in the plant you can trace it — and when a run goes well, you can repeat it exactly.
Blended or Pro — which line is yours?
The two lines feed the same plants in different ways. The choice comes down to how you like to mix and how big you grow.
Blended Line — liquid, ready to pour
For home and craft growers. A two-part base (Grow A & B in veg, Bloom A & B in flower) measured straight from the bottle, with CaMg and PK added on top to fine-tune the feed. Blended runs on variable EC — the feed strength steps up and down week by week following Athena's chart. Sizes 0.9 L, 3.78 L and 18.9 L.
Start with Grow A & B →Pro Line — dry, mixed to concentrate
For larger and commercial rooms. Dry powders you dissolve into a stock concentrate: Core runs the whole cycle, paired with Pro Grow in veg or Pro Bloom in flower. Pro runs on constant EC — you hold one feed strength and simply switch Grow for Bloom. Far lower cost per litre of feed at scale. Boxes of 4.53 kg and 11.34 kg.
Start with Pro Core →
Pick one line and stay with it. Blended and Pro are separate systems with their own feed charts — don't mix Blended base parts with Pro base parts in the same reservoir. The rule of thumb: if you'd rather measure millilitres from a bottle, go Blended; if you're filling a large tank and want the lowest running cost, go Pro.
Running DWC or RDWC? Use the Blended Line. Athena publishes a dedicated RDWC procedure and addback calculator for the Blended Line only. The Pro Line has no DWC procedure — it's built for commercial fertigation in media like rockwool and coco, not for roots sitting in a recirculating reservoir. For deep water culture, run Blended Grow A & B and Bloom A & B with CaMg, and follow Athena's Blended RDWC procedure.
What each product does
Blended Line
Liquid, measured from the bottle. Variable EC — for home and craft growers, and the line for DWC/RDWC.
Athena Blended Grow A & B
Two-part base for the vegetative stage, with extra nitrogen for leaf and stem growth.
Athena Blended Bloom A & B
Two-part base for flowering, weighted toward phosphorus and potassium.
Athena Blended CaMg
Calcium, magnesium and iron, added through veg and flower. Also the part that lets you lift EC without changing the base ratio.
Athena Blended PK
Phosphorus and potassium booster for flowering, dosed to the feed chart.
Athena Blended Balance
Potassium silicate that raises and buffers pH. Especially useful if you run RO water.
Athena Blended Cleanse
Keeps irrigation lines and drippers clean and running between and during runs.
Pro Line
Dry powders mixed to a concentrate. Constant EC — for larger and commercial rooms running fertigation.
Athena Pro Line Core
Calcium nitrate with chelated micronutrients. The base used every week, veg and flower.
Athena Pro Line Grow
Paired with Core through the vegetative stage.
Athena Pro Line Bloom
Replaces Pro Grow alongside Core once flowering starts.
Athena Pro Line Balance
Powdered pH up for fertigation systems.
Athena Pro Line Fade
Nitrogen-free liquid finisher that replaces Pro Line Core for the final 3 weeks of flower.
Athena Pro Line Starter Mix Kit
Pre-measured pouches and jugs for making your first concentrates accurately.
Crop protection, for either line: Athena IPW is Athena's essential-oil based crop-protection spray, formulated for soft-bodied insects and powdery mildew. Always read and follow the label directions.
Feed charts and getting started
Athena publishes full feed schedules for both lines in metric and imperial through the Athena Growers Hub. Follow the chart for your line, check EC and pH at the drip or runoff, and change one thing at a time. That's the whole method — and it's why Athena works as well for a first tent as it does for a production room.

FAQ
I'm running one tent at home — which line should I buy?
Blended. It's measured by volume straight from the bottle, the 0.9 L and 3.78 L sizes suit one or two tents, and there's no concentrate to prepare. Start with Grow A & B, Bloom A & B and CaMg, then add PK and Balance as the chart calls for them.
What does "variable EC" and "constant EC" actually mean?
EC is feed strength. On the Blended line the chart changes the strength week to week through the run. On the Pro line you hold one strength for most of the cycle and change what's in the feed — Grow in veg, Bloom in flower — rather than how much. Constant EC is simpler to manage at scale; variable EC gives a home grower more control week by week.
Do I need every bottle in the Blended line?
No. Grow A & B and Bloom A & B are the base and are required. CaMg is used in most setups, particularly with RO or soft water. PK, Balance and Cleanse are tools you add as your water, medium and system need them.
Will it clog my drippers or dosing pumps?
No — that's one of Athena's core design points. Both lines are 100% soluble, so they won't settle out in a reservoir or block drippers, venturis or peristaltic dosers when mixed as directed.
What medium is it designed for?
Athena is a mineral nutrient built for fertigation in inert media such as rockwool and coco, and for hydroponic systems. Their feed charts assume that kind of setup, which is where the published EC targets apply most directly.
Can I use Athena in DWC or RDWC?
Yes — use the Blended Line. Athena's recirculating deep water culture procedure and addback calculator are written for Blended only; there's no equivalent for the Pro Line, which is built for commercial fertigation in media. In a DWC reservoir, Blended is the line Athena supports.
Is this genuine Athena stock?
Yes. Every bottle and box is genuine Athena product, held in our Sydney warehouse and shipped domestically, with questions answered here rather than through an overseas seller.
