If you have been examining your hydroponic system for more than two weeks, you have probably already observed pH fluctuations in your hydroponic reservoir. The two numbers will identify whether a hydroponic system is feeding your plants or your plants do not absorb nutrients; you should get a hydroponic EC and pH guide that can help you grow your plants.
If you get EC and pH readings wrong, you will see deficiency symptoms such as slow growth and root problems; without understanding why this is happening, you cannot find an effective solution. The Hydroponic EC and pH Guide explains why potential hydrogen and electrical conductivity are important in a hydroponic context.
pH measures whether your solution is acidic or alkaline on a scale of 0 to 14. If your solution’s number is below 7, the solution is acidic; if it is above 7, then the solution is alkaline; whereas if it is exactly 7, then your solution is neutral.
In hydroponics, pH can affect nutrient availability, and it may happen if your solution contains all the nutrients required for plant growth because plants can absorb those nutrients within a specific range. If your solution’s pH value gets outside the pH range of 5.5 to 6.5, these nutrients become chemically unavailable in the solution, and the plant will not absorb them.
What Is the Reason Behind pH Fluctuations?
In a hydroponic system, pH fluctuations in hydroponic reservoirs are common because the reservoir is active chemistry:
- Plants take up water and ions
- Roots exchange charged particles
- Source-water alkalinity buffers the solution
- Microbes transform compounds
- Growers add water and nutrients
- Rapid, repeated, and extreme movements deserve investigations
Start by asking Hydroponic EC pH Guide Questions
- Is pH rising or falling?
- How quickly can it change?
- Does it change after or before specific addition?
- Are plants and roots healthy?
It is not the right method to solve every change by adjusting the pH level; verify the reading, record the trend and identify the driver.
How to Test and Adjust pH and EC
- pH Testing
pH can be tested with pH paper, and the cost of paper is low, but it has low to moderate accuracy; or the pH level can be tested with a pH meter, which is more accurate and needs calibration.
Digital meters require calibration with buffer solution within 1 to 2 weeks, and probes should be stored in electrolyte solution. To lower the pH level, generally phosphoric acid or citric acid products are added to the solution, whereas potassium hydroxide can be added to increase the pH value of the solution.
- Testing EC
Electrical conductivity meters are inexpensive and simple to use, as you dip the probe in the solution and read the value; calibration is suggested every few weeks in a standard solution. Add more nutrient concentrate to increase the EC level of the solution and add plain pH-adjusted water to lower it.
- How Often To Test
For most hydroponic systems, testing every two to three days is ideal to get proper knowledge about your solution, and pH drifts faster than EC in most systems. Follow a few steps for testing, including:
- Test pH and EC at the same time of day
- Twice a week
- Write both numbers with the date
- Add nutrients if EC has dropped
- Need to adjust if pH level is out of range 5.5 to 6.5
- A tub or bucket is enough for a daily glance
Conclusion
Hydroponics is a method of crop production in which no soil is needed, and nutrients are supplied through a liquid solution. In this method, plant roots may or may not be supported by artificial substrate such as perlite, vermiculite and coconut coir or a mixture of these, Hydroponic EC pH guide Coventry, which helps to improve productivity without harming the environment.
In hydroponics, management of nutrients is a very crucial step, and there are four main characteristics to focus on:Total salt concentration, pH, alkalinity, and nutrient concentration ratio.
