Can you use dehumidifier water to water your plants?

Dehumidifiers are often used to reduce the humidity levels in our homes, offices and other enclosed spaces. They work by drawing in air from the environment, extracting moisture from it, and then releasing the dry air back into the room. However, did you know that the water collected by dehumidifiers can also be used to water your plants? In this article, we will explore the benefits and drawbacks of using dehumidifier water for your plants.

The benefits of using dehumidifier water for your plants

One of the main benefits of using dehumidifier water for your plants is that it is free of charge. You are already paying for the electricity needed to run the dehumidifier, so you might as well make use of the water that is collected. Dehumidifier water is also generally free of contaminants like chlorine and other chemicals that are found in tap water. It is therefore ideal for plants that are sensitive to such substances.

In addition, dehumidifier water is often slightly acidic, which is beneficial for plants that grow best in acidic soil. If your tap water is alkaline, using dehumidifier water can help you to balance the pH levels in your soil. Finally, dehumidifier water is at room temperature, which can be an advantage in the summer months when the cold water from the tap can shock your plants.

The drawbacks of using dehumidifier water for your plants

One of the main drawbacks of using dehumidifier water for your plants is that it lacks the valuable nutrients that plants need to grow. Tap water contains minerals like calcium and magnesium that are essential for the healthy growth of plants. While dehumidifier water may be free of contaminants, it is also free of these essential nutrients. You may therefore need to supplement your plants with fertilizer to make up for this deficiency.

Another drawback of using dehumidifier water for your plants is that it can be high in salt. This is because the dehumidifier extracts moisture from the air, which can contain salt particles from seawater or other sources. Over time, the accumulation of salt can damage your plants and make it difficult for them to absorb water and nutrients. You should therefore limit your use of dehumidifier water and flush out your soil with tap water periodically to remove any excess salt.

Conclusion

Can you use dehumidifier water to water your plants? The answer is yes, but with some caveats. While dehumidifier water is free of contaminants and may be slightly acidic, it is also lacking in essential minerals like calcium and magnesium. Moreover, it can be high in salt, which can damage your plants over time. If you choose to use dehumidifier water, be sure to supplement your plants with fertilizer and flush out your soil with tap water periodically to remove any excess salt. With these precautions, you can enjoy the benefits of using free and chemical-free water for your plants.
