Question: can N. ventricosa tolerate 218 ppm TDS water?
Jeff Dallas: 218 ppm is pretty hard. Will tolerate, but supplement with rain/distilled water. If using tap regularly, repot annually. Mention: "Zero Water" pitcher filter (ion exchange) removes minerals—cheaper upfront than RO for small amounts.
Good Growing!
