The Athena Pro Mix Kit is the gold standard for professional cultivators in the UK looking to transition to a high-performance, dry-fertiliser regime. This all-in-one starter solution provides the exact components required to mix the industry-leading Pro Line nutrients with precision and ease.

By utilizing dry salts, you significantly reduce shipping costs and plastic waste while maintaining total control over your nutrient concentration.

Why the Athena Pro Mix Kit is Essential for UK Growers

In the professional UK hydroponic market, consistency is everything. The Pro Mix Kit eliminates the guesswork, ensuring that every batch of feed you create is chemically balanced and perfectly dissolved for use in high-performance irrigation systems.

What’s Included in the Kit

  • Athena Pro Bloom: A concentrated dry fertiliser specifically formulated for the reproductive stage of plant development.

  • Athena Pro Core: The essential foundation of the Pro Line, providing the nitrogen and calcium required for all stages of growth.

  • Athena Pro Grow: Optimized for the vegetative phase to promote rapid structural growth and lush foliage.

  • Precision Measuring Tools: Mixing Containers: Specialized vessels designed to facilitate the rapid dissolution of dry mineral salts. High-quality hardware to ensure your mixing ratios are accurate down to the gram.

Key Performance Benefits

  • Ultra-Pure Solubility: Specifically engineered to be 100% soluble, preventing any clogs in drippers, sprayers, or complex fertigation systems.

  • Cost Efficiency: Dry nutrients offer a much higher value per litre of feed compared to pre-mixed liquids, especially for large-scale UK facilities.

  • Total Nutrient Control: Easily adjust your EC and NPK ratios to match the specific needs of your strain or environment.

  • Long Shelf Life: Unlike liquid nutrients, dry salts are extremely stable and can be stored for long periods without losing potency.

The Athena Pro Mix Kit provides a streamlined 5-step process to create high-precision concentrated "stock" liquids from dry mineral salts. This method is preferred over weighing dry powders for every reservoir change because it ensures a consistent mineral balance and prevents the nutrient deficiencies that can occur from inaccurate dry measurements.

Mixing Instructions for Concentrate Stock Tanks

  • Step 1: Prepare the Vessel: Use the specific 1-gallon (3.79L) jug provided in the kit for each nutrient part—Core, Grow, and Bloom.

  • Step 2: Add Dry Nutrients: Pour a single 2lb (907g) pouch of dry nutrients into its matching jug.

  • Step 3: Initial Water Fill: Fill the jug about halfway with water (Reverse Osmosis water is recommended for best results).

  • Step 4: Dissolve: Shake the jug vigorously until the powders are fully integrated and no sediment remains.

  • Step 5: Top Off: Once the powder has dissolved, top off the jug to the final 1-gallon fill line and shake again to ensure a uniform concentration.

Important Usage Rules for UK Growers

  • Never Feed Directly: These stock liquids are highly concentrated; you must never apply them directly to your plants.

  • Mixing Order in Reservoir: When adding your finished concentrates to a main reservoir, always add Pro Core first, followed by Pro Grow (in veg) or Pro Bloom (in flower).

  • Prevent Precipitation: Do not combine the concentrated liquid products together in their undiluted form, as this will cause the minerals to precipitate and render the formula useless.

  • Water Quality: These formulas are optimized for soft water or RO water with a starting EC no higher than 0.4. If using harder tap water (EC above 0.6), you may need to reduce your dosage to reach your final target EC.

  • Storage: Keep jugs tightly closed in a cool, dark environment (between 7°C and 29°C) to maintain maximum shelf life.

Frequently Asked Questions

The Athena Pro Mix Kit is an all-in-one system designed to help growers accurately prepare concentrated liquid stock solutions from Athena Pro Line soluble fertilisers. It includes the essential Pro Core, Pro Grow and Pro Bloom components required for a complete vegetative and flowering nutrient programme.

The kit includes Athena Pro Core, Pro Grow and Pro Bloom soluble mineral fertilisers together with matching concentrate mixing containers. The exact pouch and container sizes depend on the Pro Mix Kit size selected.

Athena Pro Core is the foundation nutrient used throughout the growing cycle. Pro Grow is paired with Core during the vegetative stage, while Pro Bloom is paired with Core during flowering. This creates a simple two-part feeding programme for each major stage of plant development.

Creating stock concentrates helps make nutrient preparation faster and more consistent. Athena advises that repeatedly weighing powders can result in variations between batches. Preparing a correctly mixed concentrate first allows growers to measure the required liquid dose accurately into their reservoir or irrigation tank.

Add the appropriate amount of RO or filtered water to the supplied mixing container, add the matching Athena Pro Line fertiliser and mix thoroughly until the powder is completely dissolved. Top up to the specified volume and mix again before use. Always follow Athena's instructions for the specific kit size and feed programme.

Yes. The Athena Pro Line is designed for precision mineral feeding and is particularly well suited to hydroponic cultivation and modern irrigation systems. Prepared concentrates can be accurately dosed into reservoirs or irrigation tanks according to the Athena Pro Line feed schedule.

Athena Pro Grow is formulated for the vegetative stage, helping provide the mineral nutrition required while plants establish structure and foliage. Athena Pro Bloom takes over during the flowering phase and is designed to support the nutritional requirements of developing flowers. Both are used alongside Athena Pro Core.

The Athena Pro Mix Kit is ideal for growers who want a clean, precise and repeatable nutrient programme without continually weighing dry fertilisers. It's particularly useful for hydroponic growers, larger grow rooms and irrigation-based setups where accurate nutrient preparation and consistency between batches are priorities.
