Condensate water is a great resource for plant irrigation. The best source for condensate water for your plants is your home's air conditioning unit. Depending on the type, a home air conditioning unit produces anywhere between one and 20 gallons of water per day as it cools the air. The water is naturally sterile, low in mineral content and unchlorinated, which makes it perfect for watering your plants. Plus, recycling this water is a great way to cut down on your utility bills during the hot summer months.
Locate the point where the condensate water leaves your air conditioning unit. It will be located somewhere on the back corner of your unit, either dripping directly out of the unit or directed through a condensate tube.
Cover the top of the bucket with cheese cloth or some other mesh material to keep any debris out. Secure it with a length of string and then press the center of the mesh down until it is 4 inches beneath the lip of the bucket.
Set the covered bucket beneath the condensate drip.
Use the condensate water to water your plants as needed.
