Before comparing feeding routines, compare what comes out of the tap. Compare product measurements alongside your feed chart.
The acidity or basicity of the sample at measurement.
The water’s acid-neutralising capacity. It is not another name for pH.
A conductivity reading—not an ingredient list.
Read calcium, magnesium, sodium and chloride individually.
Two waters can share a pH and react differently.
Starting pH alone does not describe buffering. A water with greater alkalinity can require more acid to produce a similar pH change. Knowing only “my water is pH 8” does not tell us the final pH after adding a particular feed.
Make your report useful.
- Keep the source, sampling date and laboratory name.
- Keep units beside every result. Alkalinity expressed as CaCO₃ and bicarbonate are different reporting bases.
- Record the complete recipe and water volume.
- Measure the finished mix and note when the reading was taken.
- Repeat consistently when the source or recipe changes.
This is a useful first conversation with us: your water report, medium, current feed, crop stage and what you are observing. A pH number by itself leaves too much unanswered.
See the difference for yourself.
Compare our separate-product measurements in tap and purified water. Use the results to understand the tests, then measure your own complete mix.
