Pulling Water Out of Thin Air

If it's dry outside but humid in your basement or bathroom, then you can use a dehumidifier to lower the humidity levels. The dehumidifier essentially cools the air in a small space. By lowering the temperature, the water vapor condenses in water droplets, thereby lowering the humidity level in a room. You can see the same occur when you have an ice cold drink outside on a hot day. When your dehumidifier's tank is full, take the tank out and water some of your plants. While this another way to reduce the amount of tap water used on irrigation, do not use your dehumidifier in rooms with open windows. The humidity levels inside will not decrease by much since you will have more water vapor coming indoors from the outside air. Do you have other ways to reduce the water used on irrigation? Feel free to share. I'd love to try them out.
