The Importance of pH in a Hydroponic System
In recent years, hydroponic systems have gained a lot of popularity, and it's not hard to figure out why that is. Hydroponic systems are advantageous for a variety of reasons due to their capacity to cultivate plants without the need of soil. These advantages include increased agricultural yields, reduced water use, and accelerated rates of plant development. Hydroponic systems do require a certain degree of attention to detail, though, just like any other technique of producing plants, particularly when it comes to the pH levels.


How would you describe the pH scale?
A solution's acidity or alkalinity can be measured using the pH scale, which is used in chemistry. On the pH scale, values range from 0 to 14, with 7 representing neutrality. A pH level that is lower than 7 is considered acidic, and a pH level that is higher than 7 is considered alkaline. In a hydroponic system, the pH of the nutrient solution should be carefully monitored and kept within a certain range. This range is normally between 5.5 and 6.5, however certain plants may have a prefered range that is different from this.

Why is the pH Value so Critical in Hydroponic Systems?
It is absolutely necessary for the health and vitality of your plants to maintain the appropriate pH level in a hydroponic system. If the pH of the solution is too high or too low, the nutrients in the solution will become less accessible to the plant. This will eventually lead to nutritional shortages, which can cause the plant to die. In addition, pH values that are too high can cause particular nutrients to precipitate out of the solution and adhere to the walls of the reservoir, which renders them inaccessible to the plants. This can happen when the pH level is too high.

The Value of Conducting pH Measurements
In order to keep the pH of the nutrient solution within the ideal range in your hydroponic system, you will need to do pH tests on a regular basis. There is more than one way to determine the pH of a substance, and these ways range from easy and cheap to difficult and expensive. Using a paper test kit is the most fundamental method, which includes dipping a strip of litmus paper into the solution and comparing the resulting colour to a chart to establish the pH level. This is the most straightforward method. Paper test kits, on the other hand, can be less precise than other techniques and might not offer an accurate measurement of the pH.

The Importance of Testing pH
You may also determine the pH of a solution by using a liquid test kit. This approach entails adding a few drops of the nutrient solution to a vial of indicator liquid and comparing the colour of the mixture that is produced to a chart. The accuracy of liquid test kits is higher than that of paper test kits; nevertheless, liquid test kits still require careful attention to color-matching, and they can be more expensive than paper test kits.


A digital pH pen is used by many hydroponic gardeners because it provides more precision and is simpler to operate. These gadgets have a straightforward operation and give a digital display of the pH level. Yet, digital pH pens need to be calibrated on a regular basis to ensure reliable readings.

Hydroponic pH Level Regulations and Adjustments
There are a few different approaches you may take in order to modify the pH level of your hydroponic system in the event that it falls outside of the recommended range. The nutrition solution can have modest amounts of pH adjusters, such as solutions that raise or lower the pH, added to it in order to restore the pH level back within the acceptable range. These adjusters may be applied by hand or mechanically with the use of a pH dosing pump. Since they provide the highest level of accuracy and provide continuous monitoring of pH levels, automatic pH dosing pumps have become a popular option for use in larger hydroponic systems.

Improving Nutrient Uptake with Humic and Fulvic Acids
Humic and fulvic acids have been shown to improve nutrient absorption.
There are other ways to improve nutrient absorption in hydroponic systems, in addition to monitoring and altering the pH levels in the solution. Using humic and fulvic acids is one example of such a strategy. The absorption of nutrients by plants can be aided by these naturally occuring organic compounds, which also makes those nutrients more accessible in the nutrient solution. You may get humic and fulvic acids in ready-to-use solutions like Green Planet Nutrients GPH and GPF. These are products that include humic and fulvic acids and can be used right away. RAW Another possibility are the humic and fulvic acids.
