How to Lower the pH in Hydroponics? Know the Easy Ways!
Let’s face it, you should not expect your plants to grow to their full potential in any system if the surroundings are not optimal. Hydroponics system is also no exception in which you grow plants without soil. Since there is no soil to provide nutrients to the roots, this role is fulfilled by the liquid nutrient solution. But what if I tell you that the nutrients in the nutrient solution won’t matter if the pH is not in the optimum range (Reason is being described later in this article).
Generally, liquid in hydroponics has higher pH and you have to take some measures to reduce it. So, How to Lower the pH in Hydroponics without spending a huge sum of money?
Here, I am describing to you three easy ways in which you can reduce the pH levels in hydroponics easily and swiftly. So, if you own a hydroponic system or planning to build one in the future, then this article might be the most important thing you will read today. So sit back, relax, and read every word carefully!
Why You should adjust pH?
Most of the plants like to grow in a slightly acidic surrounding (5.5 to 6.5). So, it becomes necessary to slightly reduce the pH to provide those plants a perfect condition to grow.
Moreover, if you are growing plants in a higher pH range, then prepare yourself mentally to witness a decline in plant quality. If the pH is up or down, nutrients available around the roots of the plants become useless. How? Well, in an undesirable range, nutrients are literally “locked,” hence, plants are not able to uptake any nutrients even if they are present in a large amount.
Even if you keep adding fertilizers in such pH, it will do no good for plants as roots have no power to absorb the nutrients in such conditions. That is why experts stress that plants should be grown in such an environment where the pH is according to their needs.
In Hydroponics, the situation gets even more critical as the soil is not used as a source of nutrients here. You supply a nutrient solution that should have an ideal pH.
If it does not, then roots can’t do much and plants will turn out to be weak and susceptible to diseases. That is why keep on checking the pH of the solution when you are making a nutrient solution. The reason is that as you add nutrients, the pH of the solution starts changing. So, keep on your toes during this process and keep measuring the pH.
But what if you end up with a higher pH which happens in most cases. Don’t worry, it is not a reason to panic as I am here to tell you about how to reduce pH in hydroponics.
How to Lower the pH in Hydroponics?
In search of an answer, people search how to lower pH in Water for hydroponics plants. Well, it is hard to find authentic ways to do this on the internet. That is why I am here to help you get out of this misery. Below are the three proven methods to reduce the pH in hydroponics:
How to Lower the pH in Hydroponics with pH Down?
pH Down is a General Hydroponics product that is widely used by hydroponics growers to increase acidity. pH Down liquid contains phosphoric acid that effectively reduces the pH of the nutrient solution.
The manufacturer General Hydroponics recommends using it carefully in a small amount at a regular interval until you reach the desired pH.
To do this, you need to have pH measuring strips or a pH meter. Add a little liquid to the nutrient solution or water and then measure the pH. Keep doing this until you get the pH you are looking for. This is the quickest and most reliable method among the ones I am describing in this article. So, whenever a person asks, How to Lower the pH in Hydroponics, the first answer that comes to my mind is pH Down.
pH Down Hydroponics is an effective hydroponic pH stabilizer when you grow these plants:
- Vegetables
- Herbs
- Fruits
- Flowers
If you are growing plants in the following growing media, then pH down will be highly effective:
- Rockwool
- Coco
- Peat moss
How to Lower the pH in Hydroponics with Lemon Juice (Citric Acid)?
People often ask me, how to lower pH in water naturally and the answer is very simple. Take a lemon, cut it, and squeeze the juice in a cup or spoon. Mix 2 tablespoons of lemon juice in a gallon of water and then mix it in the nutrient solution to increase the acidity.
Lemon juice is acidic in nature and is used to make pH-lowering solutions to reduce the pH. But just like pH down, you have to keep checking the pH here as well to avoid “extra-reducing” the pH.
How to Lower the pH in Hydroponics with Vinegar?
In addition to lemon juice, if you want another answer to how to naturally lower pH in the hydroponics question, then I recommend vinegar.
You can add vinegar to increase the acidity of the liquid naturally in the hydroponics. The application of vinegar is also pretty straightforward too.
Two cups of vinegar in a 10-gallon liquid reduces the liquid pH by 0.35 to 0.5, which you can measure from pH strips. If you are growing in a smaller hydroponics system, then adding two tablespoons of vinegar should be enough for the same purpose.
However, it is not a desirable method as it is effects are short-lasting. You will need to add vinegar, again and again, to maintain the pH in the required range.
pH is now reduced more than Requirement: How to raise pH in hydroponics?
If by chance you end up with a pH lower than the requirement, then you should opt for some measures to increase the pH. Want to know how to raise the pH level in hydroponics in an effective way? Well, you can raise pH in hydroponics with baking soda due to its alkaline nature. Keep adding it in small amounts until you reach the desired pH range. To know about this, you should keep measuring the pH with the help of pH strips or a pH meter.
You can add lime to reduce the acidity levels of the liquid. But the best method I know is to add pH Up by General Hydroponics. Its application is similar to the pH down described above.
Final Words
All in all, there is no denying that proper pH levels of nutrient solution are important to growing top-quality plants in hydroponics. Every grower should give special attention when it comes to the acidity and alkalinity of the medium. As most of the plants love a slightly acidic surrounding (5.5 to 6.5 pH), the most common thing a grower does is to make the liquid a little acidic.
But How to Lower the pH in Hydroponics and give plants exactly what they want? You can do this with the help of pH Down by General Hydroponics, vinegar, or citric acid (lemon juice). All you have to do is apply any one of these treatments in the recommended way!
I am certain that if you follow what has been suggested, then you will surely end up with plants giving high yields in the soil-less system.
FAQs about How to lower ph level in Hydroponic System
How do you increase and decrease pH in hydroponics?
You should know how to change pH in hydroponics if you want a higher yield. If the pH is not in the required/recommended range, then you have to take some measures to increase and decrease the pH. Many people ask, how to raise the pH level in hydroponics without harming plants. To increase the pH, you can use, pH Up by General Hydroponics, baking soda, and lime.
To decrease the pH, you should add pH down by General hydroponics, citric acid, and vinegar. That’s how to lower pH in Water for plants.
Can you use vinegar to lower pH in hydroponics?
Yes, you can use vinegar to lower the pH/increase the acidity. Two cups of vinegar in a 10-gallon liquid reduces the liquid pH by 0.35 to 0.5, which you can measure from pH strips. If you are growing in a smaller hydroponics system, then adding two tablespoons of vinegar should be enough for the same purpose.
How do I bring my pH down?
