The Athena Pro Mix Kit 2.5 Gal is a complete 3-part dry-soluble nutrient starter system containing pre-measured 5 lb pouches of Pro Core, Pro Grow, and Pro Bloom, plus three labeled 2.5-gallon mixing bottles with dispensing spigots. It uses Athena’s concentrate-first workflow, allowing each nutrient to be prepared separately at a consistent concentration and then dosed into feed water without weighing individual powders. The larger format is designed for commercial operations that need more concentrate per mixing session than the 1-gallon kit.

Key Advantage: The 2.5-gallon kit provides the same concentrate-first, standardized mixing workflow as the smaller 1-gallon kit but produces substantially more concentrate per batch. The pre-measured 5 lb pouches eliminate weighing errors, while the dedicated spigot-equipped bottles make dosing cleaner and easier for higher-volume commercial fertigation.
