Is distilled water good for indoor plants?
From what i know, some people say it's good, others don't agree .
Any advice/info/experience will be appreciated

  @Ungrimironfist Distilled is not good as the substrate and fertilizers are produced to combine with tap water. But usually you'll want to reduce the general hardness. ➡️ https://en.wikipedia.org/wiki/DGH?wprov=sfla1
  To find out your degree you can purchase test material in a aquaristic shop. If you have no rain water at hand you can filter tap water with the same techniques like you'd do for coffee/tea water. The same is used for pools.

    DGH
    
    Degrees of general hardness (dGH or °GH) is a unit of water hardness, specifically of general hardness. General hardness is a measure of the concentration of divalent metal ions such as calcium (Ca2+) and magnesium (Mg2+) per volume of water. Specifically, 1 dGH is defined as 10 milligrams (mg) of calcium oxide (CaO) per litre of water. Since CaO has a molar mass of 56.08 g/mol, 1 dGH is equivalent to 0.17832 mmol per litre of elemental calcium and/or magnesium ions. In water testing hardness is often measured in parts per million (ppm), where one part per million is defined as one milligram of calcium carbonate (CaCO3) per litre of water. Consequently, 1 dGH corresponds to 10 ppm CaO but 17.848 ppm CaCO3 which has a molar mass of 100.09 g/mol. See also Carbonate hardness Hard water dKH References Frank, Larry (1997-12-16).

  @Irisfreundin As ferzilizers do. You need to repot frequently of course.

  The filter for coffee/tea are ion exchangers. They exchange calcium ions for sodium ions. This salinizes the soil.

  @Irisfreundin Yay, salts are the enemy.

  Good fertilizers do not contain sodium. This is poison for plants.
  I do not repot frequently. My older plants only every 5-10 years. There was never a salination of the soil. It's a question of the fertilizer's quality I think.
