Athena Pro Grow

Athena Pro Grow – Professional Powdered Grow Nutrient

Athena Pro Grow is a fully water-soluble powdered base nutrient designed to support strong, healthy vegetative growth in hydroponic and horticultural growing systems. Formulated as part of the Athena Pro Line, Pro Grow provides a carefully balanced supply of nitrogen, phosphorus, potassium, magnesium and other essential minerals to support root development, healthy foliage and vigorous plant growth.

With an NPK ratio of 2-8-20, Athena Pro Grow is designed to be used alongside Athena Pro Core, which supplies additional nitrogen, calcium and essential micronutrients. Together, they form a complete mineral feeding programme for the vegetative stage.

Its highly soluble, large-grind powder is ideal for preparing concentrated stock solutions, making Athena Pro Grow particularly suitable for automated fertigation, commercial irrigation systems and growers who prefer the flexibility of powdered nutrients.

Designed to dissolve at room temperature with minimal sediment, Pro Grow provides a practical solution for growers looking for consistent nutrient delivery without the need to store and transport large volumes of liquid fertiliser.

Why Use Athena Pro Grow?

During vegetative growth, plants need a balanced supply of essential nutrients to establish healthy roots, develop strong stems and produce the foliage required for photosynthesis.

Athena Pro Grow has been formulated to provide the mineral nutrition required during this important stage of development.

Phosphorus supports energy transfer and root development, while potassium contributes to water regulation, enzyme activity and normal plant growth. Magnesium is an essential component of chlorophyll, helping plants carry out photosynthesis efficiently.

When combined with Athena Pro Core, the feeding programme also provides additional nitrogen, calcium and essential micronutrients, helping maintain balanced nutrition throughout vegetative development.

Its powdered format is particularly useful for growers using automated irrigation systems, as it allows concentrated nutrient stock solutions to be prepared and delivered at controlled rates.

Understanding the Nutrients in Athena Pro Grow

Athena Pro Grow contains a range of essential mineral nutrients that support healthy vegetative development.

• Nitrogen (N): Supports chlorophyll production, amino acid formation and healthy foliage development.
• Phosphorus (P): Important for energy transfer, root development and normal plant metabolism.
• Potassium (K): Supports water regulation, enzyme activity and the movement of nutrients within plants.
• Magnesium (Mg): An essential component of chlorophyll, supporting photosynthesis.
• Sulphur (S): Required for the formation of certain amino acids and proteins.
• Iron (Fe): Supports chlorophyll formation and important metabolic processes.

Pro Grow is designed to work alongside Pro Core, which supplies further nitrogen, calcium and micronutrients needed for a complete feeding programme.

How Athena Pro Grow Works with Pro Core

Athena Pro Grow is not intended to be used as a standalone base fertiliser. It must be combined with Athena Pro Core to provide the complete Athena Pro Line vegetative nutrient programme.

Pro Grow supplies phosphorus, potassium, magnesium and other minerals, while Pro Core provides additional nitrogen, calcium and essential trace elements.

Using separate components helps maintain nutrient stability in concentrated stock solutions, particularly where calcium-containing fertilisers could otherwise react with phosphates or sulphates.

When preparing a reservoir solution, use 0.6g of Pro Core for every 1g of Pro Grow, following the appropriate Athena feeding schedule.

How to Use Athena Pro Grow

Athena Pro Grow can be mixed directly into a nutrient reservoir or prepared as a concentrated stock solution for use with compatible automated dosing systems.

Always measure powdered fertilisers accurately by weight rather than volume.

Mixing Athena Pro Grow in a Reservoir

When mixing directly into a reservoir, use Athena Pro Grow alongside Athena Pro Core at the recommended ratio of 1g Pro Grow to 0.6g Pro Core.

1. Fill your reservoir with the required amount of clean water.
2. Measure the required amount of Pro Grow according to your Athena feeding schedule.
3. Add Pro Grow to the water and mix thoroughly until completely dissolved.
4. Measure Pro Core at 60% of the weight of Pro Grow.
5. Add Pro Core to the diluted nutrient solution and mix thoroughly.
6. Allow the nutrients to dissolve completely.
7. Measure the electrical conductivity (EC) of the finished nutrient solution.
8. Check and adjust the final pH according to your crop and growing system.

Important: Never mix Pro Grow and Pro Core together as dry powders or undiluted stock concentrates. Always dissolve and dilute each product separately to prevent unwanted mineral reactions.

Preparing Athena Pro Grow Stock Concentrate

Athena Pro Grow can be prepared as a concentrated stock solution for professional fertigation and automated nutrient dosing systems.

Maximum stock concentration: 1.1kg of Pro Grow per 4 litres of water, according to the supplied product instructions.

1. Use a clean stock tank or suitable mixing container.
2. Add the required quantity of clean water.
3. Accurately weigh the required amount of Pro Grow powder.
4. Slowly add the powder to the water while mixing.
5. Continue agitation until the powder has completely dissolved.
6. Store Pro Grow concentrate separately from Pro Core concentrate.
7. Connect the prepared stock solution to a compatible dosing system.
8. Adjust the injection rate according to the required nutrient strength and feeding schedule.
9. Check the EC and pH of the finished nutrient solution.

Do not exceed the recommended maximum stock concentration. Solubility can vary depending on water temperature and quality.
