Ro water for plants is a type of water that you can use if you are passionate about gardening. Ro water, or reverse osmosis water, is possibly the purest form of water produced by a unique reverse osmosis process and is very useful for the healthy growth of plants.

Reverse Osmosis Water for Plant Cultivation

Virtually, you cannot have a better option to water your outdoor or indoor plants, especially if they are delicate, because it permits you to have almost total control over the nutrients your plants absorb. Keep reading the article to know all the necessary information on reverse osmosis water for plants

What Makes Reverse Osmosis Water Special?

⚡️ Reverse osmosis water is special because it is the purest form of water that can be produced after putting it under pressure, which reduces the amount of minerals in it. On that note, plants and crops that are irrigated using this type of water will thrive.

– Purifying Water

During this process, a semi-permeable membrane which is also known as the synthetic lining, pushes water with the use of pressure to point out and clean unwanted molecules and large particles, including contaminants and residues like chlorine, salt, and filth, from the water to purify it. 

Purifying Water for Better Health

Due to this procedure, most of the pollutants discovered in the water are removed, including thrash metals, salts, chlorine, and more. We all know distilled water is very pure, but interestingly reverse osmosis water is more refined than that. 

The reverse osmosis process eliminates some minerals as it holds more giant molecules than water carries. While the water gets through the semi-permeable membrane, the membrane catches minerals and removes them. Minerals get dragged along with nutrients as it eliminates 90 to 99.99 percent of water pollutants, and the process considers minerals one of the pollutants. 

– Soft Water

As minerals make hard water and reverse osmosis removes minerals from water, reverse osmosis water is regarded as soft water. Some homeowners establish a whole-house water softener to soften the water before it is purified by reverse osmosis, reducing supervision expenses throughout their houses.

This pure of water also removes the chlorine from the water, but only the reverse osmosis method cannot eliminate all of the chlorine in the water. To remove chlorine, you will need to add a block of activated carbon as an element of the reverse osmosis process that can eliminate 98 percent of water chlorine.

– Water Acidity Level

Reverse Osmosis water usually has a pH of between 6.0 and 6.5 at the final stage, but sometimes reverse osmosis water has a pH of 7.0 to 7.5, which are acidic comparatively.

What are the Advantages of Using Reverse Osmosis Water for Plants?

The advantages of using reverse osmosis water for plants is that the plant would receive the full nutrition, it has reduced chlorine which would boost the roots’ health. Additionally, the roots will absorb water quicker, and the plant will have fewer pollutants. Also, this water is great for every plant.

– Plant Receives Full Nutrition

Using reverse osmosis water for your plants ensures the permanent management of clean and unpolluted water. The most significant benefit of using the water is getting the full grasp of your plants’ nutrition, as you can control what is in the reverse osmosis water and what you give to your plants. 

On another note, significantly this water for plants is a blessing for serious gardeners, and plants love it more than distilled or tap water because it is adaptable to their fertilizer and pH levels because of the absence of heavy metals or other contaminants.

– Reduced Chlorine Boosting the Roots

RO water is also helpful for the thriving of indoor plants or house plants. Regularly providing adequate sunlight and water to the plants is necessary for indoor plants’ healthy growth. But tap water has too much chlorine, so using tap water frequently can harm plants.

Reduced Chlorine on Stronger Plant Roots

In such cases, you can purify tap water with a reverse osmosis water filter system to ensure your indoor plants’ well-being.

– Roots Absorb Quickly

As there are several contaminants that exist in the water, the plant food needs to fight for space in the water, and the absorption process gets delayed. But when there are no contaminants in the water, the plant food or nutrition can be absorbed faster, which makes your plant healthier and more lively.

The reason why the roots would absorb the water quicker is that there is no blockages that would be standing between the root passages and the soil. RO processes can remove up to 99 percent of all pollutants and contaminants in tap water, including metals like VOCs, arsenic, fluoride, and chromium, along with substances like bacteria and viruses. 

As this type of water and the cleansing process turns water purest and returns it to its basic form, plants get the opportunity to receive all necessary nutrients from the water

– Less Pollutants

Reverse osmosis is perfectly satisfactory for plants due to not having heavy metals or other pollutants that create problems with their fertilizer and pH levels because of its high-quality water filtration method. The less pollutants are found in water, the better the quality of the new bloomers will be, as the plant would not feel the harshness of the water that would be bothering it. 

Effects of Pollutants on Plant Life

However, you can always dilute it at first with regular tap water before watering your plants as this water is high in TDS, and high TDS water for the long term can decrease the fertility of your garden’s soil, which would mean that it would have fewer pollutants.

– For All Plants

The greatest deal here is that this water is all good for all kinds of plants, whether outside or inside plants. You can use this water for outdoor flower beds, inside containers based flowers, or even for tank farming and aquaponic water puddles. Due to holding a more stable pH than tap or distilled water, it’s the better watering solution for your plants.

What are Some Drawbacks of Reverse Osmosis Water for Plants?

There are two major drawbacks to reverse osmosis water for plants which are the plants would lack nutrients when they are growing. As a result of the latter, in the later run, the plants may be killed, because of their weakness.

– Lacks Nutrients

Reverse osmosis water has different drawback as it would aim to remove every element from the water, including good vitamins, nutrients, and other beneficial minerals, which can create a lack of nutrients problem.

Another disadvantage of reverse osmosis water is maintaining the system for producing this water is too much expensive. If you have a tight budget, you have to leave the idea of giving your plants ro water.

– Kills Plants

Yes, ro water can kill your plants as it doesn’t have the necessary minerals, including calcium, magnesium, nitrogen, potassium, which are essential for the growth of plants.

Water Can Be Harmful to Plants

You can avoid the death of your plants by mineralizing the ro water sometimes and by giving your plants not only ro water always, hence if you are wondering does ro water kill plants, then you should be careful.


Reverse osmosis water is simply the best option to water your plants. Now you know how it gets produced and what is the benefits and disadvantages of using this water but let’s summarize the points to keep in mind from this article before wrapping up the write-up.

  • Reverse osmosis water is usually considered the cleanest and best water for your plants.
  • This water contains a very trifle amount of contaminants as the ro process removes up to 99.99 percent of pollutants, including minerals and chlorine.
  • As there are almost no contaminants in reverse osmosis water, plant food gets absorbed faster with this water while provided to plants which ensure healthier plant growth and helps them to be more lively, comparable to the plants getting tap water or distilled water.
  • Though it’s one of the most nutrient water for plants, spring water is the most nutrient or oxygen-enriched water.

Though ro water has some drawbacks, being a better choice than distilled water and filtered water allows you to have complete control over the nutrients you give to your plants. As the cleanest and purest form of water, reverse osmosis water can be a blessing to your garden.
