Frequently Asked Questions
What is Athena Proper?
Athena Proper is a liquid add-on feed from Athena, and the first "synganic" formula in their Athena Modified line. It combines a high concentration humic and fulvic component with balanced phosphorus, potassium and micronutrients. Athena built it to go into your irrigation alongside your normal Athena feed, with the aim of better terpenes, flavour, aroma and yield. It is for growers already running Athena Blended or Athena Pro who want to push quality further.
When do I use Athena Proper in my feed schedule?
Use it in flower only. On Athena's updated Modified feed schedules, Proper is left blank for clone and veg in both programs. On the Modified Blended schedule it runs from week 3 to week 9 of flower, starting at 3 mL per gallon and peaking at 8 mL in week 7. On the Modified Pro schedule it runs from week 4 to week 8 of flower, at 9 mL for weeks 4 to 6 and 5 mL for weeks 7 and 8. These are Athena's baseline figures, so follow the current Athena schedule for your run length.
Can I use Athena Proper with both Athena Blended and Athena Pro?
Yes. Athena publishes a Proper line on both the Modified Blended and the Modified Pro feed schedules, with different weeks and amounts for each. Pick the schedule that matches the base nutrients you already run, and do not mix the two sets of numbers. If you are not sure which Athena line suits your setup, our Athena procedures and feed schedules guide explains the difference.
Does Athena Proper replace Athena Cleanse, Balance or my base nutrients?
No. On both of Athena's schedules Proper sits as an extra line, and Balance (or Pro Balance), Cleanse and the base nutrients are all still listed. It is an add-on, not a swap. The one swap on the schedules is Fade replacing Core late in flower, and that is a separate thing from Proper.
When will Athena Proper be available in the UK and how much will it cost?
We are expecting Athena Proper in Q1 2027, and the price is still to be confirmed. We have not got a firm date from Athena, so we are not promising one. You cannot order it yet. It sits in our Incoming Products collection until it lands, and any figure showing on the page for now is only a placeholder.
What results does Athena say Proper gives?
Athena reports averages across 18 strains with harvest data, compared with their baseline: grams per square foot up 13.6%, terpenes up 25.6%, aroma score up 9.4% and flavour score up 12.8%. Those numbers come from Athena's Crowdsourced Research network (70 trials, 45 growers, 45 grow environments). They are Athena's figures, not ours, and your own results will depend on your strain, room and feeding.
Description
Athena Proper Synganic Humic and Fulvic Formula is a liquid add-on feed from Athena for growers who already run Athena Blended or Athena Pro and want better flavour, aroma and terpenes at the finish. It is the first "synganic" formula in the Athena Modified line: a high concentration humic and fulvic component with balanced phosphorus, potassium and micronutrients. You use it in flower, fed through your normal irrigation.
Coming Q1 2027. Price to be confirmed.
We are expecting Athena Proper in the first quarter of 2027 and we do not have a firm date, so we are not promising one. You can look but you cannot order yet. Any price showing on this page is a placeholder until Athena confirm UK pricing. Want a nudge when it lands? Keep an eye on our Incoming Products collection.
Athena Proper Synganic Humic and Fulvic Formula: what it is and when you use it
Athena make a lot of nutrient lines, and Proper is a different sort of thing from the base feeds. It is a modifier. You do not feed it on its own, you add it to your Athena programme at the weeks and amounts on Athena's schedule. Athena built it from their Crowdsourced Research network. Over two years they tested polysaccharides, fulvics, seaweed and botanical extracts, organic acids, amino acids and different levels of phosphorus, potassium and micronutrients. Their finding is that fulvics, optimised phosphorus and potassium and a balanced micronutrient profile together improve nutrient use efficiency, which helps plants reach their genetic potential, with gains in yield, terpenes, flavour and quality.
Athena also say their modifiers are designed to fit into the irrigation system you already have.

How Athena Proper is dosed
Athena publish two updated Modified feed schedules (the "V2" PDFs), one for the Blended program and one for the Pro program. Proper is not listed in clone or veg on either of them, it is a flower input. The figures below are copied straight from those schedules. They are in mL per gallon, and Athena are clear it is a baseline: adjust the chart to the weeks your run needs and remember it is strain dependent.
| Athena Proper, Modified Blended program | Flower W1 | W2 | W3 | W4 | W5 | W6 | W7 | W8 | W9 |
|---|---|---|---|---|---|---|---|---|---|
| mL per gallon | None | None | 3 | 4 | 6 | 7 | 8 | 4 | 4 |
| Athena Proper, Modified Pro program | Flower W1 to W3 | W4 | W5 | W6 | W7 | W8 | W9 |
|---|---|---|---|---|---|---|---|
| mL per gallon | None | 9 | 9 | 9 | 5 | 5 | None |
A couple of things worth knowing. The Pro schedule says its amounts are based on a 2 lb per gallon stock tank concentrate, and Athena recommend mixing Pro from a stock tank, so read their Pro Concentrate Procedure before you mix. On the Blended schedule, Proper runs right through to week 9 alongside Fade. On the Pro schedule, week 9 swaps Core for Fade and Proper is not listed. Always check you are using the latest Athena schedule for your run.
The Athena program: Adapt, Optimize, Enhance, Pursue
Athena frame the Modified line around four ideas. These are Athena's own words for what the program is aiming at.
| Athena program pillar | What Athena says it is for |
|---|---|
| Adapt | Support terpene expression, aroma, and flavour |
| Optimize | Deliver consistent results across every grow |
| Enhance | Elevate crop quality while controlling costs |
| Pursue | Push a proven program to its full potential |
What Athena's research says about Proper
Proper came out of Athena's Crowdsourced Research network: 70 trials with 45 growers in 45 grow environments, boiled down to one formula. Here are the average results Athena report across 18 strains with harvest data, compared with their baseline.
| Metric (average vs Athena's baseline) | Change reported by Athena |
|---|---|
| Grams per sq ft | +13.6% |
| Terpenes | +25.6% |
| Aroma score | +9.4% |
| Flavour score | +12.8% |
These are Athena's published numbers, not ours. They are averages, so some grows did better and some did worse, and your room, strain and feeding will move the result.
Steady EC feeding
Athena's Modified page also covers what they call Steady EC feeding. You keep the same EC from start to finish and change how much feed the plant gets by changing the number of irrigation events instead. With proper substrate dry-backs, Athena say this causes "EC stacking", which raises the nutrients available during the high demand weeks. They also say it makes batch tank mixing simpler and cuts down mixing mistakes. Our guide to mastering EC is a decent primer if that is new to you.
Run it with the rest of your Athena feed
Blended program: Athena Blended Grow AB, Athena Blended Bloom AB, Athena Blended CaMg, Athena Blended Balance and Athena Blended Cleanse. New to Athena? The Athena Blended Starter Kit is the easy way in.
Pro program: Athena Pro Line Grow, Athena Pro Line Bloom, Athena Pro Line Core and Athena Pro Balance.
Both: Athena Fade for the finish. Looking for another flavour and aroma additive in the meantime? Have a look at Technaflora SugarDaddy.
In the Box
Athena have not published a box list for Proper, so all we can say for certain is one sealed Athena container of Proper in the size you choose, 1 Gallon or 5 Gallon. If a cap, seal, spout or measuring aid comes with it, keep it, those small bits are the first things to get binned and the last things you can find when you need them. The 5 Gallon is a bulk container, so sort out somewhere to store it before it lands. A tap makes it far easier to dispense, and the 5 Gallon Tap Spigot is worth a look if you do not already have one.
