The Importance of the pH levels in Hydroponics


It is impossible to overestimate the relevance of pH balance in your hydroponics system to the health and vitality of your crop.

If the pH isn’t in the right range, your plant won’t be able to absorb essential minerals and micronutrients. Vitamin deficiencies and, in the worst-case scenario, death might happen as a result of this.

Plants will lose their ability to absorb some of the important nutrients required for long-term development if the pH levels are outside of the appropriate range.

Plants have varying ideal pH values, with the majority preferring somewhat acidic growing conditions yet thriving in the 5.0 to 7.5 pH range.

When a lot of fertilizers and micronutrients precipitate out of the solution and stick to the walls of the hydroponic reservoir, it’s called a hydroponic reservoir.

What are pH levels?

It assesses how acidic or basic a solution is, to put it simply.

According to a more scientific definition, it represents the concentration of hydrogen ions in a liquid. A high pH suggests a lower hydrogen concentration, whereas a low pH indicates a higher hydrogen concentration.

For people with a chemical background, the pH of any material may be calculated using the formula pH = -log [H3O+].

However, this method isn’t the only approach to figuring out the pH of water. This post will go through what causes it, the issues with acidic and basic water, and how to test your water for it at home.

Let’s have a look at the following bulletins about pH

  • The root system can take nutrients from the water, and it works best when the soil and water are balanced, which means they agree or are close to agreeing.
  • The pH is equal to log10c, where c is the mole per litre concentration of hydrogen ions.
  • The potential hydrogen-hydroxyl ion content of the solution is a less technical term.
  •  Positive (hydrogen) and negative (hydroxyl) ions form bonds in solutions. If a solution has more positive ions than negative ions, it is considered acidic and has a pH of 1–6.9.
  •  If a solution contains more negative ions than positive ions, it is considered to be alkaline and has a pH between 7.1 and 14.
  • Maintaining the pH balance of reservoir water can be a difficult challenge for growers at times. This is especially true for rookie hydroponic gardeners who may not realise the need to maintain optimum pH levels in the fertiliser solution. 
  • While it may appear to be a hassle at first, maintaining optimum pH levels provides several advantages for your plants.

What Are the Benefits of efficient pH maintenance?

Proper pH levels in your hydroponics systems may have a significant impact on your plants’ development and health. 

No matter how good your hydroponic nutrients are, it won’t be reflected in your green, leafy growth if you don’t have healthy pH levels. 

Maintaining the pH of your hydroponics system is vital since it can help your plants absorb nutrients more effectively. 

The key advantage of maintaining proper pH levels for your plants is that they will be able to absorb nutrients more effectively, resulting in healthier and stronger plants.

The other benefit is that it allows the grower to examine his or her set-up for any potential issues that may have emerged as a consequence of changes in environmental conditions or plant requirements.

It improves photosynthesis, which is the process by which plants produce their own food from light, water, and carbon dioxide.

When two pigments in plants called chlorophylls (chlorophyll A and chlorophyll B) receive light energy from the sun, photosynthesis occurs. 

This energy is subsequently passed to enzymes in the leaves of the plant, allowing them to convert carbon dioxide and water into glucose and oxygen. 

Plants consume glucose as a source of nutrition. 

Photosynthesis cannot proceed efficiently or at all if there is insufficient light, water, or carbon dioxide.

It’s also vital to check on your plants on a frequent basis because certain plants need slightly different pH levels than others.

About Chemboys pH UP

pH UP by Chemboys is designed for use in both soil and soilless gardening. When added to a nutrient solution, it acts as a pH buffer, raising the pH to the ideal range for plants (6.0-6.8).

It’s no secret that high-quality fertilisers may help you grow plants that are greener, more robust, and yield more. 

However, these nutrients are worthless if the plant is unable to absorb them through its roots due to a pH imbalance. 

Your plants will not be able to absorb all of the nutrients you provide them with without adequate pH management, no matter how high grade they are.

  • The pH UP from Chemboys is used to elevate the pH of the water to the appropriate level.
  • It’s designed specifically for changing nutrient solutions in soilless hydroponics.
  • When combined with alkaline materials like lime or wood ash, Chemboys pH UP acts as an acid neutralizer (buffer).

The Final Verdict

pH levels are critical in hydroponics, as you can see. Because your plants are growing in water, they will require more care than plants grown in traditional soil-based methods.

A pH that is even a few degrees higher or lower than the optimal pH can be devastating.

If you’re ready to venture “beyond soil” into the world of hydroponics, you’ll need to understand what equipment you’ll need and how pH levels will play a role.
