EI Dosing Starter Pack – Macros & Micros

The Estimative Index dosing method can seem intimidating to hobbyists accustomed to all-in-one products, but this starter pack removes the guesswork by bundling a pre-calibrated macro solution and micro solution in 250ml bottles alongside a clear printed dosing guide. Both solutions are formulated to EI-method target concentrations, so following the guide produces the correct nutrient levels without any measuring or mixing.

The macro solution contains nitrate and phosphate at standard EI ratios with an elevated potassium component. The micro solution contains DTPA-chelated iron and a full trace element profile at EI-appropriate concentrations. Used together three times per week with a 50% weekly water change, they provide the nutrient saturation that drives the lush, fast growth EI is famous for.

This pack is the ideal entry point into two-part dosing for hobbyists upgrading from all-in-one products and wanting to understand how individual nutrients work.
