Three kinds of information.
- Product guidance
- The current label and feeding chart guide use of the finished product. General ingredient articles are not replacement instructions.
- Our measurements
- The water tool reproduces the supplied single-product pH worksheet. Starting water differs between some product tests. Paired readings remain visible. Missing alkalinity, calibration and test-date records limit the conclusions.
- Published research
- Research is identified by material, crop and conditions where discussed. Findings for an ingredient are not automatically findings for a Crazy Hills formula.
Read a comparison carefully.
Same product and dose, two recorded waters: useful observation. A complete feed, another water source or a claim about a competing brand: a different question requiring its own evidence.
Keep a record worth sharing.
Include date, product and batch, water report, full recipe, water volume, temperature, meter calibration, mixing order, measurement timing and every reading. Repeat observations and retain unexpected results. Describe which conditions were kept the same.
