Homemade soilless cultivation nutrient solution/private formula for reference
When it comes to soilless cultivation, everyone is probably not particularly unfamiliar with it, but it is not necessarily the case that they have a deep understanding of it. Nowadays many people have simply heard of soilless cultivation, but in fact their understanding of it is very shallow. The most important thing in soilless cultivation is the preparation of the soilless cultivation nutrient solution, and generally people have their own formula for preparing this kind of nutrient solution. So what is homemade soilless cultivation nutrient solution all about? What are some good formulas? Let us take a look together below.
Introduction to soilless cultivation
First let us briefly understand what soilless cultivation is. Although everyone often hears this term now, they are still extremely unfamiliar with soilless cultivation itself. So-called soilless cultivation is actually a modern seedling-raising technique that uses lightweight materials such as peat or forest leaf mold and expanded vermiculite as a seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts mechanized precision sowing to produce seedlings in one go. It is used in many greenhouses nowadays and often used in plant hydroponics, and it is a very good technique. It does not need any soil, and without the drawbacks of parasites in soil, using it to raise seedlings is very convenient.

1. The nutrient solution is the main source of mineral nutrients and water needed by soilless cultivation crops, and it plays a very key role in soilless cultivation, so its quality directly affects the results of soilless cultivation later on. Therefore, preparing the nutrient solution becomes the top priority, and every step in it must be treated with caution. Generally speaking, the components of the nutrient solution are all related components needed by plants, such as the major and medium elements nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, and the trace elements iron, manganese, boron fertilizer, zinc and copper, and so on, so when making it yourself these components are what must be prepared and added.
2. Most of the nutrient solution is water, so the water quality in it is very important. The plastic seal must absolutely not contain harmful substances for plant growth, and the water quality cannot be too hard or too soft. Some need specially treated water, while for others tap water is fine; the actual situation decides specifically.
3. When people carry out soilless cultivation, in order to make the plants grow better, they often apply some fertilizer in appropriate amounts, so the nutrient solution must also have good solubility for fertilizer. In the process of making it yourself, you must ensure that the nutrient solution has good solubility.
