A significant step on the way to optimal yield is optimal growing conditions for your plants. This already starts with the right pH values. By using a pH meter correctly, you can ensure optimal conditions for your plants at every stage of their growth. The cultivation of cannabis is indeed an art form, but primarily it is a science. To thrive, your plants need precisely the right conditions. This already starts with the correct chemical composition of the soil and the water around the plants.
Due to soil contamination and chemicals being dumped in to the water for public safety reasons, the basics of your plantation may not be the best. Cannabis plants are susceptible to such inconsistencies. As a consequence, and to determine if your growing conditions are the way they should be, you must use a pH meter. Also, you should check your plants throughout growth again and again. You measure the pH value. It affects the ability of plants to transport their nutrients and carbohydrates. Cannabis thrives at a pH of about 6.5. Your task is to organize the cultivation medium and water in this area.
It’s easy. Changes in the pH of soil and water stress your plants. Even if the pH of the soil is right, but the pH of the water does not match, the whole plantation is endangered. The growing plants absorb water, which is transported via the trunk to the leaves. There it evaporates. Water is exchanged for carbon dioxide. In combination with light, CO₂ is used to produce vital sugar for the growth of the plant.
This process is called photosynthesis. If soil and water do not have the correct pH, photosynthesis is less active. This, in turn, leads to far from optimal plant growth and reduced performance of the plants. It also means less income. Another critical point is that cultivation without soil requires a different pH. That’s why you have to adjust your pH meter. The ideal pH of the earth is between 6.0 and 7.0. In an alternative growing medium (such as coco substrate ) or hydroponic plants, it is between 5.5 and 6.5. That’s why it’s so important to be able to adjust correctly and work with a pH meter.
The easiest way to adjust the pH of your soil and water is to use a pH meter. Most are pretty easy to handle. Just move the pH meter back and forth in the water or put it in the ground to measure the pH. The problem is that they often have to be calibrated first, and you have to readjust them regularly.
We’ll give you some essential tips on how to calibrate your device correctly. Depending on whether you test with a “pen” or manually, the procedure may vary slightly. You need to make sure your device measures the pH accurately.
- Study the user manual for your device. The omission of this first and most crucial step is the main reason why some pH testing attempts “fail.”
- Calibrate regularly.
- Always wear gloves when testing and calibrating, as your body can influence the test results.
- Put a small amount of the test solution in a separate container. You can either buy the answer in a shop or use a substance with a known pH. Commercially available solutions contain several pH test solutions. For example, a set may include pH solutions with values 4, 7, and 10.
- Clean the tester and always use a fresh solution for checking.
- Immerse the tester in the first pH solution to adjust the pH meter.
- Clean the tester after the first test and test two more times.
- Now put the calibrated pH meter in the medium or liquid you want to measure.
- Read the value.
- Adjust the pH accordingly, depending on the result.
There are a few proven rules to make sure your calibrations are correct.
- Use the right buffer solutions. PH meters work best when set slightly above or below the desired test range.
- Learn what the chemical composition can quickly change in both directions. Garden lime, for example, can make soil and water more alkaline, while white vinegar makes both substances more acidic.
- If the pH does not fit, rinse your plants with suitable water. This also regulates the pH of the earth.
- Pay particular attention to hygiene when testing. Always use a fresh buffer solution. The pH meter must also always be clean. Any contamination will affect the test result.
- Proper storage is crucial. All pH meters contain a very sensitive pH electrode. If it is damaged, you can no longer rely on the test results.
- Do not use distilled or deionized water at any time. This can damage the glass sensor.
