Description
Hydroponic Research – Stax
Hydroponic Research Stax (formerly known as Stackswell) is a high-performance powdered additive designed to maximise plant growth and efficiency. It combines humic acids, calcium, sugars and magnesium into a single, easy-to-use formula, replacing multiple additives with one powerful product.
Developed specifically for large-scale and professional growers, Stax delivers measurable improvements where small gains can make a significant difference. By improving nutrient uptake and root efficiency, it supports faster growth, stronger plants and increased resilience. As a result, crops develop more consistently across all growth stages.
In addition, the humic acids in Stax help improve nutrient availability, while calcium and magnesium support structural strength and metabolic function. The added sugars further enhance plant performance and stress tolerance. Together, these components improve drought resistance and overall plant health.
Stax is fully compatible with the entire Hydroponic Research nutrient range and performs reliably across hydroponic systems, coco coir and soil. Manufactured in California, it meets the demands of modern commercial growing environments.
