1、 Self making method of nutrient solution

The first is inhibitors, such as adding salt or something to inhibit bacteria. For example, add aspirin or sugar. If you add a single substance to the water, it is difficult to solve the nutritional level

You can make your own nutrient solution at home. You can find a composition table called MS culture solution on the Internet and buy different chemicals according to the composition table. This nutrient solution is to divide the medicine into different proportions, dilute it with pure water respectively, and mix it according to a certain proportion. When using, after completely mixing the medicine, it can be injected into the water body

2、 Precautions

1. Ready to use: these solutions must be ready to use immediately before use, because some chemicals will have various problems after being placed for a period of time, such as precipitation, reaction and denaturation with other substances

2. Concentration mat: some medicaments belong to trace elements, and the amount of application is very small. The concentration to be prepared is very thin, so they must be operated strictly. Once the concentration is high, it may inhibit plant growth and even produce toxin poisoning, that is, excessive poisoning of some elements

3. Operate according to requirements: some chemicals will conflict when put together, so they must be operated according to requirements, prepared into different solutions, mixed before use, and immediately added to the water body in order to play a role and avoid some unnecessary effects. Such nutrient solution configuration requires certain chemical knowledge and operation skills, so there are certain difficulties in the operation process. Of course, there are skilled flower friends and flower friends with certain chemical skills. There should be no too much pressure in the operation
