The influence of ph:

Generally, low pH value can easily cause root rotten, yellow leaves or fall off for most hydroponic plants.

- 1. PH value affects the activities of plant roots:

Plant roots can carry out normal metabolic activities only within a certain pH range, including respiration, ion exchange, absorption of various nutrients, etc. Although different plants adapt to different pH ranges, the pH of the rhizosphere of general plants is required to be between 5.4 and 6.3. If it is higher or lower than this range, the activity of the plant root system will be inhibited, and it may even cause root necrosis in severe cases, resulting in the death of the entire plant.

- 2. PH value affects the effective release of nutrient elements in the cultivation substrate:

The nutrient elements in the cultivation substrate exist in a variety of forms, such as compounds, ions, chelates, etc. Some forms of elements cannot be absorbed and utilized by plant roots, such as Fe, Ca, Mg plasma if it is at a high pH value In the matrix, they will combine with OH roots to form insoluble or slightly water-soluble compounds, so these elements cannot be effectively absorbed by plants.

3. The influence of PH on rhizosphere microbial activity:

Some microorganisms in the substrate are beneficial to the growth of plants, and some even have a symbiotic relationship with plants, such as mycorrhiza; the life activities of microorganisms are also carried out within a certain pH range, and beneficial microorganisms can help plants absorb nutrients and decompose Organic matter, secretion of organic acids to improve soil quality, etc.

The influence of ppm:

Hydroponic nutrient solution is the core part of hydroponics, and it plays a vital role in the success or failure of hydroponics.

- 1. The suitable ppm value of hydroponic nutrient solution affects the hydroponics grow:

The hydroponic nutrient solution should be prepared in strict accordance with the prompt ratio, and the ppm (concentration) should not be increased arbitrarily. Because the tissue structure of the root system that sprouted in the hydroponic environment has changed, it is looser than soil cultivation, the cells are larger, and the cell wall is thinner. In the absence of the buffer effect of the soil on the inorganic elements, it directly absorbs water, nutrients and nutrients from the hydroponic nutrient solution. Oxygen is extremely sensitive to the concentration of nutrient solution. Too high concentration will be harmful to plants. The concentration of macro-elements should be less than 500PPM ( Please refer to the corresponding ppm asking of that plants in the book or web). A lower concentration is beneficial to the growth of most plants. A lower nutrient solution concentration is also beneficial to increase the dissolved oxygen content.

- 2. Stable ppm value of hydroponic nutrient solution can avoid pathological damage caused by hydroponics:

The hydroponic nutrient solution needs to be replaced after a period of use. Since the plants selectively absorb the required inorganic elements during the growth process, the nutrient solution ions are out of balance, which may cause the plant to produce element-deficient physiological diseases.

During the growth and development of plants, the old roots decay and die, and new roots continue to sprout. The roots will secrete wastes, which will deteriorate the quality of the hydroponic nutrient solution and hinder the normal physiological metabolism of plants. Therefore, the hydroponic nutrient solution must be replaced regularly. The time to replace the hydroponic nutrient solution should be changed according to different seasons and temperature changes, according to the approximate ppm value, and pay attention not to damage the root system of the hydroponic plant when replacing it. In addition, the hydroponic nutrient solution should be clear and transparent, and suddenly become turbid due to unknown reasons, or there may be mosquito eggs, larvae, or moths, which should be replaced immediately.



SO, Is there some one interested to test the ph & tds meters please? I am looking for some one to test our ph & tds meter and post a honest review, I can provide you the ph meter and tds meter by free.

By the way, the ph meter and tds meter is very suitable for the person who start their hydroponics.

If interested, please do not hesitate to contact me :) mail: [email protected]

Have you sold any of these on ebay or anything so we can see some reviews?

You haven't posted any pics of mentioned product, pictures can really help.

But IMAO this post smells like honey, you will find everyone here already has what you mentioned from tried and trusted companies.
