Athena Nutrients Blended Line Balance – pH Buffer & Silica Supplement for RO Water
Athena Balance is a potassium silicate-based additive designed to stabilise pure or reverse osmosis (RO) water before mixing nutrients. Because RO water has an unstable chemical structure, it can bind to and “trap” added nutrients, causing lockouts and pH swings. Balance buffers the solution, creating a more stable environment for fertilisers to dissolve evenly, while also providing the added benefit of silica to strengthen plants. The result is a more consistent feed and reduced need for constant pH adjustments.
Key Benefits
- Stabilises RO water; buffers pure water to prevent nutrient lockout and improve mixing
- Acts as a pH up substitute; reduces the need for extra pH adjustment after nutrients are added
- Fortifies plants with silica; supports stronger stems, better nutrient uptake, and improved stress resistance
- Improves consistency; helps create a homogenous nutrient solution across the tank
- Flexible use; works in coco, hydro, rockwool, or soil systems
Why You Need Athena Balance
Reverse osmosis (RO) water is stripped of minerals, which makes it chemically unstable. When nutrients are added without a buffer, the water can “steal” or bind key elements, reducing availability to your plants. Athena Blended Line – Balance solves this by adding just enough potassium silicate to create stability, ensuring nutrients stay available and evenly distributed. The silica also strengthens plant cell walls, improves tolerance to heat and stress, and supports overall growth. By buffering up front, Balance saves growers time by reducing the need to constantly adjust pH after mixing.
How Athena Balance Works
Potassium silicate acts as both a stabiliser and a plant supplement. When added first to RO water, it raises the alkalinity slightly, creating a stable base for fertilisers to dissolve into. This not only prevents precipitation and pH swings but also delivers silica directly to the plant. Silica strengthens stems and branches, helping crops handle heavy fruit and flower loads while improving stress resilience throughout the grow cycle.
How to Use Athena Blended Line – Balance
- When using RO water: Add Balance first to stabilise before mixing in any nutrients or additives.
- As a pH up substitute: Use Balance in place of traditional pH adjusters to achieve stability and supplement silica.
- Soil guidance: Apply at lighter rates when using soil to prevent over-alkalisation.
- General tip: Always mix Balance into clean water before other fertilisers for best results.
Tech Specs
- Type: Potassium silicate-based buffer and supplement
