Hydroponic orchid growing is a popular method for propagating plants, as it eliminates the need for soil and reduces the risk of fungal diseases. However, it is not necessary to grow most orchids in water, as it is dictated by the plant’s natural requirements. Water-based growing has many advantages, including eliminating the need for soil and creating an attractive orchid display.
Common challenges faced when growing orchids in water include algae growth and water quality. To overcome these issues, it is essential to monitor water levels, provide adequate light, and prune and replace water roots. Many orchids and plants will thrive with more pure water like RO, as long as they add back minerals and nutrients. However, the benefits depend on the tap water quality.
Water shortage can be a problem in summer due to the unit not meeting increased water requirements. Plan ahead and buy a bigger unit than needed. Reverse Osmosis (RO) systems can help provide the correct pH and water softness for orchid care watering needs. A standard residential system is a 4:1 system, where 4 gallons of incoming water will produce 1 gallon of pure water, with the remaining gallons being used for RO water.
Aerating a RO reservoir can have some benefits for growing orchids, but it is not always necessary or beneficial in every situation. RO water is a form of pure water, similar to rain water, and fertilizers that contain Urea as a nitrogen source when used with pure water can become too acidic and negatively impact the plant’s growth.
In conclusion, hydroponic orchid growing offers numerous benefits, including reduced soil requirements, improved water quality, and the ability to create an attractive orchid display.
📹 Can You Use Tap Water for Orchids? Do I Need an RO Unit? – Water Quality Test: pH, TDS, Hardness
Watering orchids should be a simple task, but the more you learn, the more complicated it can get. Can you use tap water to water …
Is tap water ok for orchids?
Rainwater or melted snow is the best water for orchids due to its nitrogen content and lack of chemicals used to treat tap water. Regular tap water is suitable if not softened with salts. Room temperature water is ideal, but ice cubes can be used to water orchids without harming the plant. Place up to three ice cubes on the potting medium once a week, preferably not touching the leaves. Misting orchids by hand is not recommended, but placing them on a humidity tray or running a humidifier in the room can help maintain higher humidity levels. Misting by hand is not a recommended method for orchids, but placing them on a tray with pebbles can help humidify the air around the plant.
Is distilled water ok for orchids?
The pH of an orchid mix is influenced by two main factors: the pH of the fertilizing solution and the pH of the orchid mix. Over time, the orchid mix breaks down, releasing fertilizer and water with their own pH, leaving residue. To test the pH of the mix, commercial growers typically test it every few weeks. One method is the “pour-thru” method, which involves pouring RO water through the plant until a few ounces come out the bottom. This water, called “leachate”, is then tested for pH using a pH test strip.
To maintain optimal nutrient absorption, it is recommended to keep both the pH of the fertilizing solution and the orchid mix within the optimal range. For most orchids, a pH between 5. 5 and 6. 0 is recommended. To lower the pH, use Citric Acid, while Lime or Oyster Shell can be used to raise it. Too high an orchid mix pH can lead to micronutrient deficiency, while too low it can cause toxicity.
Do you really need RO water?
RO filters have been marketed as the only solution for household drinking water in the past 10-15 years. However, public tap water in Europe and North America is generally not required for RO filters. Common reasons for purchasing RO filters include concerns about PFAS, Fluoride, and Heavy Metals. High-quality faucet filters like EcoPro can remove most of these contaminants. RO filters offer proven technology for pure drinking water, high-quality filtration for non-potable tap water with bacteria or heavy metals, and can make tap water with extremely high mineral content drinkable. It is essential to check the quality of local tap water before purchasing any water treatment equipment.
What is the best water to water an orchid with?
Gail Pabst, marketing director for the National Garden Bureau, advises against using salt-softened or distilled water for orchids. Rainwater vs tap water doesn’t matter. Green leaves indicate happy orchids, while silver or white leaves need a drink, especially if wrinkled. Brown leaves indicate overwatering. Pruning leaves removes dead or decaying ones, directing energy to healthy foliage and flowers.

Do orchids need RO water?
Orchid care watering needs vary by species, grow medium type, plant size, climate, and season. Water sources for orchids include rain, tap water, reverse osmosis, and distilled water. It is crucial to check the total dissolved salts and pH level of the water before watering. Temperature is also a significant factor in orchid care.
Rainwater, obtained from rainfall, dew, and humidity, is ideal for orchid care watering. If you don’t have a built-in water catchment system, consider using a rain barrel to harvest rainwater. Tap water is the most common source, but it should be rated as hard or soft based on total dissolved salts. A rating of less than 100 parts of total dissolved salts per million is considered soft, between 100 and 200 parts per million tds is medium soft, and above 200 parts per million is hard water.
To determine the PH level of tap water, use a TDS PPM meter or ask your local water municipality for a report. A neutral to acidic PH level of PH 7 or lower is ideal, and hard water usually has a higher more alkaline Ph level. Orchids respond best to softer water and lower Ph values.
In conclusion, orchid care watering needs vary by species, grow medium type, plant size, climate, and season. It is essential to check the total dissolved salts and pH level of tap water before watering.
Is rain water bad for orchids?
Rainwater is a natural source of moisture for orchids, as it is free from chlorine and fluoride, and contains nitrogen and oxygen.
Is distilled water better than RO water for plants?
Rainwater is the best water for plants due to its clean, chemical-free nature and high oxygen content. It promotes faster nutrient intake and plant growth by forming larger roots. Rainwater should be warmed to room temperature. Water purified without salt is ideal for cacti, succulents, tropical plants, and other houseplants. Filtered water removes toxins while retaining essential minerals and nutrients. Despite its muddy appearance, used water from fish tanks can be beneficial for plants, as it can be recycled and fertilized with nutrient-rich, chlorine-free water.
Should I use RO water for my plants?
Reverse osmosis water is ideal for serious gardeners as it allows precise control of nutrient flow to plants. It is suitable for delicate plant life, while hard water is suitable for normal house plants. Culligan can help revive gardens by checking water quality and finding the right treatment solution for common household water problems. Switching to reverse osmosis water provides cleaner, consistent water for plant growth and thrive.
Should you use filtered water for orchids?
Orchids thrive in pure water with appropriate fertilizer, but it’s important to assess the water supply. Hard water, which contains high levels of calcium, magnesium, and iron carbonates, can be harmful to plants due to buildup on faucets, cooking utensils, and pots. This can interfere with nutrient uptake and may cause dull leaves. To ensure optimal orchid growth, it’s crucial to check the water supply, whether it’s hard, chlorinated, or softened.
Can I water my orchid with coffee water?
Coffee, rich in nitrogen, antioxidants, and other nutrients, can help an orchid grow. Orchids are beloved flowers due to their calm, collected, and colorful appearance. However, the author did not inherit their grandmother’s green thumb. When their Romanian mother brought them an orchid, they obsessively watered and hovered over it to keep it alive. When the orchid started turning brown and withering, the author decided to research it, just like they do for their job. However, orchids only need a bit of attention once or twice a week when they need water.
📹 Storing My RO Water for Orchids – A New Discovery Which Needs Monitoring
Although I check my feed levels all the time, because I start with RO water and use similar amounts of feed, I rarely check my PH …
Never tested my tap water and have used right from the get go. My orchids love it and I flush my orchids about once a week and fertilize them every time I water until the watering can is empty then I just use water till the watering can is empty then I switch up my fertilizer the next time. On and on it goes and they seem to be happy. Loads of information on this article. I fee at this time too much for me to do the ph and tds stuff so I just do what I do. Have a great day and enjoy your orchids.
I use RO water now because my tap was at around 170ppm… I didn’t see much of a difference as of now but I did notice that they love the 0ppm flushes of pure pure water… I think as you said you can still have great results with tap/well water. My parents live in another neighborhood and their tap is at 25ppm only, so lucky!
……the science is the best part……Did the ppm drop with the ph or did it stay the same?…….although the ph of air or atmosphere can effect water……it would take a long time and would be very very gradual, …….the more likely answer is….. due to your high temps and vigorous growth……. the plants pulled more N from the nutrient mix…..and they left more P & K behind in the remaining mix………P & K will drop the ph of a solution…….this is very common in hydroponics …In a full hydro operation, ..that’s how they monitor the plants health…..by perusal the fluctuation of the PH and the TDS of the nutrient solution …..using monitors in the mixing rooms, or meters in your hands………you can tell what the plants are feeding on and how much.. …raising the ph may buffer your water, and help them absorb the remaining nutrients better…….but doesn’t replace the missing nutrients……just keep that in mind if your wanting them to get certain nutrients at certain times……like N during heavy growth….even though they are soaking, there may not be enough N in the mix anymore……nothing wrong with reusing nutrient mixes……but you may have to adjust them a bit…….. …..this is where a mix that uses separate Calcium nitrate…….comes in handy…….a little sprinkle and your back to growing again… …..FYI…Cannabis grower pump C02 into there grow rooms to boost growth and flower production…..but Ive never seen it effect the ph of the solutions much.
Roger! Check your instruments so that they are properly calibrated, the calibration value can change, it may be the reason you have the change in your pH value, I calibrate both pH + TDS meters once a week, I do not use powder, I use APERA instruments, cal. liqid 4.00 7.00 10.00, for TDS cal.HMs 342 ppm liqid! Happy growing!
This is the main reason why our oceans are becoming more and more acidic.I’m not a chemist,but the chemistry dehind it is pretty simple.The dilution of CO2 from the atmosphere to the water is based on the chemical reaction CO2(g)+H2O(l)–> H2CO3(l), with the final product being an acid with two hydrogen atoms. As the H2CO3(Carbonic acid) gets further diluted in the water,the final reaction is an equilibrium: H2CO3+H2O <=> HCO3 + H3O+. The H3O+(oxonium) is what actually makes the water acidic and it’s concentration becomes greater as the temperature increases(based on the Le Chatellier principle ). That’s exactly the reason why the medium goes acidic as it breaks down. Things get pretty complicated when the water is not pure and contains diluted salts(especially CaCO3) and fertilisers,then we literally talk about an unpredictable soup.
What rick says makes sense and and the science to me would suggest why would co2 bond with water h2o is already happy with its bonds so pulling co2 from the air sounds unlikely and generally greater surface area is used to off gas co2 from water not vise versa because in planted aquariums people often pump co2 in because it gernally off gases readily
