Why pH is so crucial in Cannabis indoor cultivation

Several factors must be considered when cultivating plants, and cannabis is no exception. In all these factors, one that strongly influences the development of cannabis and is also essential to optimize the growth and flowering of cannabis is the potential of hydrogen (pH). Particular attention should be paid to the importance of pH since this indicator is crucial in plant life for reasons. To help you understand the importance of pH in cannabis cultivation, it is essential to know that the hydrogen potential (pH) is measured on a scale of 14. Values from 1 to 7 are considered acid whereas 7 to 14 are considered basic. The average value of 7 on this scale determines the neutral medium.

The ideal pH for cannabis growth

The importance of pH is something cannabis growers must pay particular attention because a too acidic or basic environment can lead to the nutritional blockage of their cannabis plants. This blockage effect is preventing the root system from absorbing the different nutrients available in the soil and thus leading to slower growth of cannabis.

Relying on this scale, cannabis has an optimal growth point between 6 and 7 (pH). On the other hand, during the two main growth phases, vegetative and ph-cannabis-scale-pivertoflowering, the pH differs somewhat. For the vegetative stage, a pH between 5.8 and 6.2 should be targeted while for flowering, between 6 and 7 would be appropriate. You don’t have to worry about any of that if you use distilled water combined with Piverto’s revolutionary soil & nutrients kit.

A pH below 5 (acid) has the effect of increasing the substrate absorption. This can lead directly to the excessive consumption of manganese, iron or zinc by cannabis. In the opposite case, it can see its solubility decreasing drastically which will limit the filtration of phosphoric acid, calcium, and magnesium. A constant temperature of 26 ° C (and above) combined with a potting soil with pH between 3 and 5 becomes the perfect playground for fungal diseases. Likewise, a pH that is too alkaline (greater than 7.5) prevents the root system from gaining access to the available ions in the soil, namely zinc, copper, iron, manganese, and boron, which, once again, harms to the growth of cannabis.

How to measure pH

The easiest and cheapest way to measure a solution is to insert a sunflower paper. Using a color chart, the sunflower paper, once soaked in the solution to be analyzed, changes color depending on the pH of the liquid. You only have to associate the color of the sunflower paper with the color chart to estimate the pH of the solution. However, this method is not always accurate and can mislead the user of one or two units. The second method is to use a pH meter. Usually more expensive, but much more accurate than sunflower paper, this tool makes measurements enormously more reliable and provides the necessary precision for this type of use.

How to adjust the pH

The best way to adjust the hydrogen potential (pH) of the soil is through the watering solution. The more acidic the solution, the more the pH of your soil will tend to decrease and vice versa.

To increase the pH of the watering solution

You must use horticultural lime. No precise measurement is available, namely the exact amount of lime to be dissolved in a given quantity of water since the different soils have different pHs. It is your responsibility to test and measure the amounts specific of your environment to adjust the pH properly and thus to see your cannabis plant grow exponentially.

To reduce the pH of the watering solution

You must use white vinegar. You mix a small amount of vinegar in a quantity of water and measure with a ph paper or the appropriate tool. Repeat as necessary to further reduce the pH of the solution.

The importance of pH is crucial in the indoor cultivation of cannabis. For professional results, make sure you have the right pH for each of the different periods of cannabis growth. Or if you never want to worry about it, maximize your chances of success and use Piverto’s soil and nutrients kits with distilled water solution.
