How Do You Dechlorinate Tap Water For Plants?

Should your tap water have an excessive amount of chlorine, this could pose a challenge for your vegetation. Chlorine, not a natural component of water, may be toxic to plants, potentially causing conditions like drooping or mortality.

However, it’s possible to dechlorinate your tap water and make it safe for plants. Whether you use it for drinking or hydroponics, there are several methods available that will help get rid of chlorine from your system.


In North America, tap water is treated for safety with chlorine or chloramine (a chemical mixture of chlorine and ammonia). Chlorine kills bacteria and microorganisms that could pose a danger to humans or animals.

But chlorine can also be hazardous to plants. Before using it to water your garden or indoor potted plants, make sure the water has been dechlorinated first; excess chlorine can damage plant leaves.

Fortunately, there are several effective methods for dechlorinating tap water for plants without harming your plants’ health. Which method you choose will depend on the volume of water need to be treated.

Boiling water is an efficient way to eliminate chlorine from water. This process creates heat and aeration, both necessary for dissolving volatile chlorine molecules. Unfortunately, this step takes at least 20 minutes and may not be ideal if you need to dechlorinate a large volume of water quickly.

Another way to dechlorinate tap water is by evaporating it. This method can be especially efficient if the water is stored in a container with an expansive opening, as this exposes more surface area to sunlight and accelerates chlorine gas release and dissipation.

For serious hydroponics enthusiasts, dechlorinating your tap water can help maximize yields and minimize downtime. Commercial growers have long employed this method as a practical solution to many issues.

Dechlorinating your water is important because it can affect the pH level of your soil. Plants typically thrive best between 5.5 and 7.0, so if your water has a pH below that range, it could lead to phytotoxicity and eventually plant death.

You can try dechlorinating your water using various methods, such as adding vitamin C or sunlight or chemical treatment. All these options are cost-effective and simple to do but may not be as efficient in the long run. For a more permanent solution, consider investing in a carbon filter.


Sunlight is a vital source of energy that plants use to grow. It comes in the form of visible, ultraviolet (UV), and infrared (IR) light rays. These different wavelengths of light are necessary for photosynthesis – the process by which plants absorb carbon dioxide and water to make carbohydrates.

Carbohydrates are essential in the growth of new tissues and support new leaves and roots, without which plants would not be able to flourish.

The sun emits a variety of wavelengths, meaning all parts of plants can receive precisely the right amount of light they require. This is an enormous advantage to both plants and gardeners alike.

Additionally, plants don’t need to spend time and energy learning how to get enough light for growth; they can simply adjust their pots and windows accordingly for optimal illumination.

This is an excellent idea and makes sense since the sun revolves around Earth each day, providing constant light. How much of that sunlight reaches us depends on weather conditions such as cloud cover, and also on atmospheric composition.

As you can see, sunlight is an effective way to dechlorinate tap water for plants. The light will penetrate through the water, causing it to bubble and release chlorine into the air.

When water is at room temperature, it will quickly evaporate into the air and reduce its chlorine content. This occurs since chlorine gas weighs less than air at that temperature and will escape into the atmosphere over time.

One way to accelerate chlorine dissipation in water is by leaving it exposed to sunlight. To do this, place a container of water outside with an open top so UV rays from the sun can interact with it and speed up dissolution.

Baking soda

Are you searching for an economical way to dechlorinate tap water for plants, baking soda may be just what the doctor ordered. Not only is it an effective deodorizer and cleaner, but it also has several health advantages like relieving heartburn. Plus, baking soda has been known to enhance exercise performance as well as whiten teeth.

Baking soda has the power to neutralize acid in the body and restore pH balance, making it a popular remedy for digestive problems like heartburn or acid reflux. You can also drink a small amount of baking soda mixed with water as an effective way to keep your pH levels balanced; just remember to start slowly and increase dosage as needed.

Baking soda can also be used to effectively treat and prevent weeds. Unlike chemical weed killers, baking soda kills the weed without harming nearby vegetation due to its high sodium content that creates an unfavorable environment for weeds to flourish in.

Additionally, a combination of baking soda, water and horticultural oil can help control fungal infections that affect plants. Mix one tablespoon (2.5 ml.) baking soda with dormant oil and some liquid dish soap into one gallon of water then mist the leaves several times a week to prevent fungal blooms.

Baking soda’s antifungal properties make it a perfect remedy for bug bites and parasite infections. Simply mix baking soda and water together, apply it topically twice daily on the affected area for temporary relief.

For a cheaper and safer alternative to chemical weed killers, sprinkle some baking soda over weeds in your yard or garden. However, be sure to only use it on small areas; not extensive gardens and lawns as this could harm other plants.

Baking soda can also be used to create your own spray for controlling insect pests. It works especially well on aphids and other sap-sucking insects that feed on flowers and vegetables. Simply combine baking soda, water and canola oil in a spray bottle then mist both undersides and tops of leaves to eliminate these pesky creatures.


Chlorine is a common chemical added to tap water to prevent bacterial contamination. While not toxic in itself, chlorine can have adverse effects on plants; so, before adding it into your hydroponic or aquaponic system, make sure the chlorine has been removed from the water.

Vinegar is a tart liquid created by fermenting sugar-containing substances, like fruit or wine. It can be used as an adjutant to enhance flavor or as a preservative in pickling processes.

Acetic acid, along with trace compounds and flavorings, make up vinegar. On average, it contains between 4%-8.0% acetic acid by volume, though it may also contain other acids, alcohols, vitamins, mineral salts, amino acids and polyphenols (some of which possess antioxidant properties).

Vinegar’s distinctive flavor and pungent aroma come from a two-step fermentation process: yeasts convert simple sugars to ethanol and bacteria convert the latter back to acetic acid. Different types of vinegar are created through this double fermentation; balsamic vinegar in particular has distinct flavors and characteristics that set it apart.

Other commonly-produced vinegars include distilled vinegar, cider vinegar, malt vinegar, rice vinegar and wine vinegar. Distilled vinegar is the most accessible type and usually the best choice for cooking; however some ‘craft’ or premium varieties can be found at gourmet food stores and online retailers.

Vinegar, with its tart, flavorful, and aromatic qualities, makes an excellent disinfectant. You can safely use it to clean surfaces in and around your home including carpets and upholstery without fear of damage or staining.

Vinegar can also be used to dechlorinate tap water for your plants, an easy and secure method that eliminates chlorine from the water. To begin, leave the water out overnight or two. This allows chlorine to dissipate into the air, making it less toxic and better suited to your plants’ environment.

Boiling tap water to dechlorinate it faster is another option. This method is safer than simply leaving it outside in the sun, since heat accelerates chlorine gas release into the atmosphere. Furthermore, this faster process means your water will be dechlorinated in less time than sitting in direct sunlight for a day or two.
