Final answer:
Water that is artificially softened using a water softener is not suitable for regularly watering house plants due to its higher sodium content and lack of essential minerals for plant growth.
Step-by-step explanation:
Water that is artificially softened using a water softener is generally not suitable for regularly watering house plants.
The process of water softening involves the removal of calcium, magnesium, and other metal cations in hard water, usually through ion exchange or reverse osmosis.
While soft water is beneficial for household use, it contains higher levels of sodium and lacks essential minerals that plants need for growth.
As a result, using artificially softened water can negatively impact the health and growth of house plants.
