This is a simplified mixing screen. It does not balance individual ions or predict EC precisely from fertilizer mass. Recheck with a calibrated meter after mixing.

HOW THIS RESULT WAS BUILTDeterministic calculationEngine calculator-core-1.0.0

Method: The calculator applies the entered measurements and visible formula as a planning estimate.

Inputs used: Reservoir volume = 100 L; Current EC = 1.2 mS/cm; Target EC = 1.8 mS/cm; Stock-solution EC contribution = 20 mS/cm

Assumptions: The result uses the values, units and options shown in the input snapshot.

Scope and warnings: This is a simplified mixing screen. It does not balance individual ions or predict EC precisely from fertilizer mass. Recheck with a calibrated meter after mixing. Rounding and excluded real-world terms can make an external result differ.

UNDERSTAND THE RESULT

How this hydroponic ec and ppm target adjustment calculator works

The calculator applies the entered measurements and visible formula as a planning estimate.

A worked example

Use actual reservoir, growing-area, equipment or crop data to test a scenario.

Can this be used as a growing instruction?

No. Verify water, crop, equipment and local conditions with measured data and qualified horticultural advice.

Calculations run on your device. Review your results before exporting or sharing them.

Measure before and after every adjustment

Current EC, target EC and stock contribution should come from the same calibrated measurement basis.

EC does not reveal ion balance, so use this only as a mixing screen.
