Dillon asked if total dissolved minerals = water hardness, and if aquarium hardness test strips work for carnivorous plant water testing.
Jeff Dallas: Generally yes, but hardness specifically measures carbonate (calcium carbonate) hardness. For carnivorous plants, TDS (total dissolved solids) is most useful—we want water as pure as possible. Test strips give a good hardness indication; target ≤50 ppm.
Good Growing!
