Owner

Packages the stock solubility data approved by the owner on 2026-10-23, so flahax mix and flahax batch check that each concentrate dissolves at the entered temperature (the checker came in #94; until now every product was "not checked").

Data (src/flahax/data/solubility.json, 20 products, 0-40 °C)

  • 18 products: CRC Handbook of Chemistry and Physics, aqueous solubility of inorganic compounds at various temperatures (pp. 8-112 to 8-117).
  • Calcium nitrate (ag grade): Yara CALCINIT sheet, 1200 g per L of water at 20 °C; used as a floor from 20 to 40 °C (solubility rises with temperature); not checked below 20 °C.
  • Urea: U.S. Coast Guard CHRIS / NOAA CAMEO compilation (not a primary measurement).
  • Conversion: g of product as sold (hydrate water included) per L of stock at density 1 g/cm3. This understates solubility, so a stock that would not dissolve is never passed.
  • No sourced data: the six chelates, CH - micro, potassium citrate. They stay "not checked" and are named on the sheet.
  • Still single salt in pure water; no hidden safety margin.

Tomato (Howard Resh), RO, 100:1, 25 °C

Every sourced product dissolves with a wide margin (potassium sulfate 51.5 of 107.0 g/L; calcium nitrate 93.0 of 545.9 g/L); Mn EDTA and potassium citrate are not checked. At 200:1 and 10 °C potassium sulfate (103 g/L needed, 84.6 available) blocks the sheet.

Validation

505 tests with live PHREEQC required; strict Sphinx build clean; tools/verify_distribution.py PASS (the JSON ships in the wheel); LF.
