serbahidroponik.blogspot.com - What is pH/ppm/tds levels in hydroponic system? - The pH scale is a way to measure the Acid or Basic (base) in a nutrient solution. PH official definition is: the unit of measurement that describes the level of acidity or alkalinity of a liquid solution. It is measured on a scale of 0 to 14. The acid is in the range 0-7, with lower numbers become strong acids. A base is in the range of 7-14, with higher numbers become strong base.

PH essential nutrient solution for plants fireplace because it will affect how well each element can pass through the cell walls and maintain the plant roots. When pH is unbalanced crop nutrient solution was not able to uptake the nutrients in the water, essentially starving them, even when there is plenty of food.
PH requirements for plants that are not the same for all the plant and you do not have to grow crops with different pH requirements in a nutrient solution together. You will end up eating the crops and starve the other, no mater what you save on the pH level.
We have listed some of the requirements of crops and categorized them by Fruits, Vegetables, Herbs and Flowers for your convenience. Requirements proper plant highly dependent on many variables, so it's much more important to be in the ballpark rather than a decimal point in terms of pH.
Measuring and adjusting the pH of your nutrient solution is quite simple to do, but it must be done every day to ensure that a constant pH level. Testing can be done inexpensively (under $ 10) using a pH testing kit which generally consists of a small bottle that you put some of the solutions. Then you just add a few drops of it and shake it and comparing the resulting color to the color chart to get results. You can also use pH testing. They work basically the same but small paper strips you dip in a nutrient solution is then compared with a color chart.
If you want to be more accurate you can use pH testing meter. They are electronic and steps down to the decimal point. This testing pH meter can vary in price but are usually under $ 100.
When measuring the pH of the nutrients you want to mix with water thoroughly first to ensure correct readings. If the reading is not at the right level you need to adjust by using a pH adjuster called "pH up" and "pH down," Depending on the weather you read is to high or low. If it is used too high pH down, and if it is used too low a pH up. The pH adjuster can come in the form of dry or liquid, either will work fine but make sure you mix it completely before taking another reading. The adjuster prices vary depending on manufacturing but not that expensive.
