Athena Pro Grow 2-8-20 Soluble Vegetative Fertiliser

Athena Pro Grow 2-8-20 – Professional Soluble Vegetative Fertiliser

Athena Pro Grow is a fully water-soluble dry mineral fertiliser developed specifically for the vegetative growth stage. Featuring an NPK ratio of 2-8-20, it supplies a carefully balanced combination of nitrogen, phosphorus, potassium, magnesium, sulphur and iron to support vigorous root development, healthy foliage and consistent vegetative growth.

Designed as part of the Athena Pro Line, Pro Grow is intended to be used alongside Athena Pro Core to create a complete vegetative feeding programme for professional horticultural crops. Its highly refined mineral formulation dissolves completely at room temperature, making it particularly well suited to stock tanks, automated dosing equipment and high-frequency fertigation systems.

Key Features & Benefits

• 2-8-20 vegetative fertiliser formulated specifically for the vegetative growth phase.
• Provides nitrogen, phosphorus and potassium in a concentrated dry mineral formulation.
• 100% water-soluble when correctly prepared, with no unwanted particulates or sediment.
• Designed for use alongside Athena Pro Core for complete and balanced vegetative nutrition.
• Contains potassium phosphate, potassium nitrate, potassium sulphate, magnesium sulphate and iron DTPA.
• Contains no urea or ammoniacal nitrogen.
• Mixes completely at room temperature.
• Suitable for professional stock-tank preparation and automated fertigation systems.
• Compatible with Dosatron, Netaflex and Rhythm dosing equipment.
• Low heavy metal content according to Athena's current product specification.
• Concentrated dry format reduces the amount of water transported and stored compared with equivalent liquid fertilisers.

Why Use Athena Pro Grow?

The vegetative stage places substantial nutritional demands on developing plants as they establish roots, stems and foliage. Athena Pro Grow provides the mineral nutrition required during this phase while maintaining the clean, predictable formulation needed for precision fertigation.

When combined with Athena Pro Core, Pro Grow provides a balanced nutrient programme designed specifically for vegetative development. Its concentrated dry-salt format makes it particularly suitable for professional growers operating stock tanks, dosing systems and high-frequency irrigation programmes.

NPK & Composition

Use With Athena Pro Core

Athena Pro Grow is designed to be used alongside Athena Pro Core. Pro Grow supplies the main vegetative NPK component, while Pro Core provides complementary calcium, nitrogen and micronutrients required to complete the Athena Pro Line vegetative programme.

The two products should be dosed according to Athena's current Pro Line feed schedule and the required target EC.

Preparing Athena Pro Grow Stock Concentrate

Athena recommends preparing Pro Grow as a concentrated stock solution rather than repeatedly adding small quantities of dry granules directly to the working nutrient reservoir.

The standard Athena Pro Line concentrate is prepared at approximately 2 lb per US gallon. For metric preparation, Athena's current dosage reference uses approximately 907 g per 4 litres, producing a concentrate of approximately 226 g per litre.

1. Use a clean stock tank or measuring vessel with accurate volume markings.
2. Part-fill the container with clean water.
3. Slowly add Athena Pro Grow while continuously stirring or agitating the water.
4. Continue mixing until the granules are completely dissolved.
5. Add additional water until the required final stock-solution volume is reached.
6. Mix thoroughly again until the concentrate is completely uniform.

Important: Athena's imperial concentrate is based on 2 lb per US gallon, while its metric dosage reference is based on 2 lb per 4 litres. Always use the dosing chart that corresponds with the stock concentration you have prepared.

Pro Grow Dosing by Target EC

Once Athena Pro Grow has been prepared as a 226 g/L stock concentrate, the concentrate can be added to the working reservoir according to the desired final EC.

These figures are based on Athena's recommended 226 g/L metric stock concentrate. If a different concentrate strength is prepared, the dosing rate must be adjusted accordingly.

Professional Fertigation Compatibility

Athena Pro Grow is engineered for complete dissolution and clean operation in professional fertigation equipment. Athena specifically lists compatibility with:

• Dosatron dosing systems
• Netaflex fertigation systems
• Rhythm dosing systems
• Stock-tank irrigation systems
• Automated nutrient injection systems
• High-frequency irrigation systems

The mineral-only formulation contains no organic material and is designed to minimise sediment and unwanted deposits in reservoirs, dosing equipment and irrigation lines when correctly mixed and maintained.

Available Sizes

• 2 lb / approximately 907 g pouch – individual Pro Grow pouch where offered by SteelRoots.
• 10 lb / approximately 4.54 kg box – contains five 2 lb pouches.
• 25 lb / approximately 11.34 kg bulk bag – professional bulk format.

Select the required Athena Pro Grow size from the available product options above.

Best Practice

• Use Athena Pro Grow with Athena Pro Core during the vegetative phase.
• Measure dry fertiliser accurately by weight rather than volume.
• Prepare concentrated stock solutions before dosing the working reservoir.
• Do not combine Pro Grow and Pro Core together in their dry or concentrated forms.
• Dose each concentrate separately into the working nutrient solution.
• Add granules gradually while continuously agitating the water.
• Ensure all material has completely dissolved before use.
• Monitor EC after nutrients have been added.
• Adjust nutrient strength according to crop requirements, water quality and irrigation strategy.
• Keep stock tanks, reservoirs, filters and irrigation equipment clean.

Storage

Keep Athena Pro Grow tightly sealed and store in a cool, dry location away from direct sunlight and excessive moisture. Prevent water or contaminated measuring equipment from entering the dry product.

Important Information

Athena Pro Grow is a concentrated professional horticultural fertiliser. Application rates should be adjusted according to target EC, water quality, crop requirements and irrigation strategy. Always follow the latest Athena Pro Line feed schedule and product instructions.
