Can I water my plants with water from the dehumidifier?

Dehumidifiers are a great way to reduce the moisture in your home, but have you ever wondered what you can do with the water that they collect? Instead of just pouring it down the drain, you might be able to use it to water your plants. But is it safe to do so? Let's take a closer look.

What is dehumidifier water?

Dehumidifier water is the condensation that forms on the machine's cooling coils as it removes moisture from the air. This water is usually collected in a reservoir or directed through a hose to an external drain. It's important to note that, unlike tap water or rainwater, dehumidifier water doesn't contain any minerals or chemicals that plants need to grow.

Is dehumidifier water safe for plants?

Yes, dehumidifier water is safe to use on most plants. Because it's free of minerals and chemicals, it won't leave behind a buildup of salts or cause soil pH to become unbalanced. However, if the dehumidifier is located in an area that's contaminated with mold or other pollutants, the water it collects may not be suitable for watering plants.

What type of plants can I water with dehumidifier water?

Dehumidifier water can be used on virtually any type of plant, from houseplants to outdoor gardens. However, plants that are sensitive to chlorine or fluoride (such as some orchids) may not do well with dehumidifier water if the machine uses an air filter that contains these elements.

How should I use dehumidifier water on my plants?

Dehumidifier water should be used just like any other type of water. Simply pour it over the soil until it drains out of the bottom of the pot. Be sure to water thoroughly, but don't let the soil become waterlogged. If you have a large garden, you may want to consider a soaker hose or drip irrigation system to distribute the water more evenly.

Are there any drawbacks to using dehumidifier water on plants?

One potential drawback of using dehumidifier water on plants is that it may not contain enough dissolved oxygen. Unlike tap water, which is aerated as it flows through pipes, dehumidifier water is still and may not have enough oxygen to nourish your plants' roots. To avoid this issue, you can let the water sit for a day or two before using it, or add an oxygenating agent to your watering can.

Conclusion

In summary, dehumidifier water can be a safe and effective way to water your plants. It's free of minerals and chemicals, won't cause soil pH issues, and can be used on virtually any type of plant. However, if your dehumidifier is located in a contaminated area, or if you have chlorine- or fluoride-sensitive plants, you may want to stick with tap water instead. Additionally, be aware that dehumidifier water may not contain enough oxygen, so take steps to aerate it before using it on your plants.
