- Media compatibility; works in coco, hydro, rockwool, or soil
Why You Need Athena Stack
Even with a strong base feed, plants sometimes need an extra push to unlock their full potential. Stress, minor nutrient imbalances, or limited genetic expression can hold them back. Athena Blended Line – Stack solves these issues by delivering a natural boost that improves photosynthesis, enhances root and shoot development, and stimulates flowering. Whether you’re looking to improve germination rates, strengthen plants in veg, or push flower quality, Stack is the natural performance enhancer that fills the gap.
How Athena Stack Works
Stack harnesses the power of kelp extract—a natural source of auxins, cytokinins, gibberellins, and trace elements. These compounds stimulate cell division, improve nutrient uptake, and increase resilience to stress. When applied as a foliar spray, Stack delivers these compounds directly to the leaves for rapid absorption. As a root drench, it enriches the rhizosphere, correcting minor potassium deficiencies and fuelling plant metabolism. Even at the earliest stage, a Stack seed soak improves germination rates and kick-starts plant vigor from day one.
How to Use Athena Blended Line – Stack
- As a root drench: Mix 0.5 ml per litre of water and apply weekly. Add Stack last to your reservoir, and it may be mixed with your regular fertiliser recipe.
- As a foliar spray: Apply weekly from the final week of veg through week 4–5 of flowering, or until vertical growth slows. Spray thoroughly for best uptake.
- As a seed treatment: Mix 1 ml per litre of water and soak seeds for 1–2 minutes before planting to increase germination rates and seedling vigor.
- System use: Safe in irrigation systems; Stack contains organic ingredients, so shake well before use to prevent settling.
- Soil guidance: Run lighter feed rates in soil to avoid over-fertilisation.
