FAQ's

  • What are the benefits of using dry nutrients like the Athena Pro Line?

    Dry nutrients offer excellent cost-effectiveness, reduced shipping weight, and greater control over nutrient ratios. They are ideal for large-scale operations and experienced growers.

  • What is the Athena Blended Line?

    The Athena Blended Line is a simpler, two-part liquid nutrient system (Grow A&B, Bloom A&B) designed for ease of use while still delivering excellent results.

  • Can I use Athena with tap water?

    Yes, you can use Athena nutrients with tap water, but it's essential to check the quality of your tap water. High levels of minerals or chlorine may affect nutrient uptake and pH stability. If your tap water is problematic, consider using reverse osmosis (RO) water.

  • What is Athena Stack?

    Athena Stack is a natural plant nutrient made from premium kelp extract, designed to support overall plant growth, enhance vigour, and improve tolerance against abiotic stress.

  • What are the main benefits of using Athena Stack?

    Stack helps correct minor potassium deficiencies, strengthens cell walls, improves nutrient uptake, and boosts overall plant vitality, leading to healthier growth and flowering.


  • What is the shelf-life of Athena nutrients?

    Athena Nutrients, when stored properly in a cool, dark place, have a shelf life of approximately 2 years. However, always check the product packaging for specific expiration dates or best-by dates.

  • Are Athena nutrients organic or synthetic?

    Athena Nutrients are primarily mineral-based, meaning they are synthetic or inorganic. While they focus on high purity and quality, they are not certified organic.

  • Can you use Athena nutrients in soil?

    Yes, Athena Nutrients can be used in soil, but they are designed and optimised for hydroponic and soilless growing methods. Adjustments to feeding schedules and concentrations may be necessary when using soil.

  • How to use Athena nutrients?

    Follow Athena's feeding charts for your specific growing medium and plant stage. Begin with lower concentrations and gradually increase as needed. Always mix nutrients thoroughly in water before adding them to your system. Monitor pH and EC/TDS levels regularly.

  • Do I need Cal Mag with Athena Pro?

    Depending on your growing conditions and water source, you may need to supplement with CalMag (Athena CaMg) when using the Athena Pro Line. Always monitor your plants for signs of calcium or magnesium deficiencies and adjust your feeding accordingly.

  • Are Athena nutrients salt-based?

    Yes, Athena Nutrients are primarily salt-based, which allows for precise control of nutrient concentrations. It is important to flush your growing system periodically to prevent salt buildup.

  • Do Athena nutrients expire?

    While they don't necessarily "expire" in the sense of becoming toxic, their effectiveness can degrade over time. It's best to use them within 2-3 years of purchase and to store them properly.
