Hydroponic Nutrient Calculator

Estimate the dose needed to raise a reservoir without overshooting the target EC.

EC depends on temperature and meter calibration. Add 70-80% of the calculated dose first, then recheck.

Reservoir volume (L) Current EC Target EC ml/L to raise EC by 1.0

GUIDE

How to use it

Calculate nutrient ml from reservoir size, current EC, target EC, and product strength.

The calculation is a starting point. Check drainage, soil condition, plant condition, and season together.

Is the result exact?

It is a reference based on simple presets and volume formulas. Adjust to the real growing conditions.
