The Growth Technology pH buffer solutions are each of a known and fixed pH – 4 and 7 respectively. These can be used to check and calibrate your pH meter and should be done regularly to ensure accuracy from your pH meter.
Simply pour out a small amount to calibrate, and discard the used solution afterwards to avoid any contamination.
pH buffer 7 will calibrate your meter to neutral. It is recommended to also use pH buffer 4 to calibrate your meter so you have a two-point calibration, rather than just calibrating to one level. This just gives more reliability.
Incorrect acidity/alkali levels can damage your plants and stop them from feeding as they should be.
Pour out a small amount to use for calibration and remember to discard the used solution when finished, do not pour it back into the container as it will contaminate your new solution.
First use the PH buffer 7 solution to calibrate your meter to neutral, once this is done we recommend you then use PH buffer 4 to calibrate your meter to this level, this will give you a two-point calibration and be far more reliable than just calibrating to one.

The pH levels in small hydroponic systems can often be overlooked if a grower is focusing more on monitoring a solution’s electrical conductivity or TDS level, balancing nutrients, providing beneficial additives and avoiding algae and plant pathogen problems.
However, overlooking pH control can be perilous for plants, particularly those that rely on water supplies with high alkalinity.
The pH of the nutrient solution is a major factor in determining the uptake rate of many essential nutrient ions.
Run pH too high and the dreaded nutrient lockout looms. Often, the first sign that pH has drifted out of range is a slight paling or yellowing of the younger foliage as the plants struggle to take up certain essential nutrients.
Many inexperienced growers tend to misinterpret this so a quick check of pH is always worthwhile when troubleshooting growth problems.
Causes of pH Fluctuations in a Garden
In a healthy, well-run hydroponic system, pH fluctuations are normal and in some instances, such as recirculating nutrient film technique with a large crop of mature plants and small nutrient volume, pH changes can be quite rapid and require frequent adjustments to stay within a narrow range for optimal nutrient uptake.
As plants remove nutrient ions from the solution, the solution’s pH drifts up or down. If left uncontrolled, the pH will often drift downwards for several days after planting a new crop, after which the pH will steadily increase.
This is due to the differential uptake of ions from the solution, with the release of hydrogen (H+) or hydroxyl (OH-) ions from the root system.
As positive ions such as cations Ca2+, K+, Mg2+ are removed from the solution, hydrogen ions (H+) are released from the root system to equalize the ratio of anions to cations in the root zone and this lowers the pH of the solution.
When the crop begins an active growth phase, anions such as NO3 are taken up, which increases the pH through the release of hydroxyl ions (OH-) into solution.
Once plants are well established, most hydroponic systems tend to see a gradual and continual increase in pH over time, which is countered with doses of diluted acid.
“Excellent customer service. pH buffers arrived very, very promptly. Staff was extremely helpful in sorting out a delivery issue caused by me. Very pleased with my pH buffer 4 & 7 too. Would definitely use again.”
“Today was the first time we visited the GTP Hydronpics shop in Peterborough. We were very impressed by all the amazing nutrients, soil selections, growing pots and growing tents, tools and other gardening items! The cashier and floor staff were very helpful. We will be coming back again soon!”
William & Mags:
“ We recently visited your place last year when it was snowing. I was impressed with what I saw and help that your staff showed us. It was a Saturday morning with bad weather, you still had customers and you stayed open for us which considering the weather, was very nice of you. We bought a few items and are looking forward to getting back that way soon.“
