Hydroponics" is a plant cultivation technology that does not rely on soil. It is mostly set up indoors, and the planting environment is strictly controlled, including light, humidity, temperature, etc., to give plants the best growth conditions. "Hydroponic planting" is mainly based on off-the-ground planting frames, and water flows in the planting frames. The roots of the plants are directly planted in the water, absorb the nutrient solution and oxygen in the water, and grow through the plant growth lamp to improve the efficiency of photosynthesis. This cultivation method is called indoor "hydroponic planting".
No nutrients are available to the plants in the hydroponic growing medium. The key to hydroponics naturally lies in the nutrient solution. In this way, not only can it be easy to control the substances and nutrients absorbed by the plants, but it can also adjust the EC value of the nutrient solution so that the plants can absorb an appropriate amount of nutrients.
Types of hydroponics:
Nutrient liquid film technology adopts plastic tank. There are holes above to place plants. The plastic tank is slightly inclined so that the nutrient solution can flow into the reservoir, and then circulate continuously through the water pump.
Aeroponics suspends plant roots in the air, uses sprinklers to spray nutrient solution, and then uses air pumps to circulate air. The advantage of misting is that the oxygen supply to the plant roots is abundant.
The use of solid cultivation medium can not only fix the roots of plants, but also protect the roots. But in the same way, solid medium cultivation also depends on nutrient solution, because these solid cultivation mediums do not contain nutrients.
A typical home hydroponics plant will have the following basic equipment: a rectangular container, a reservoir, a water pump, an air pump, and a simple timer. Of course light (either natural sunlight or artificial grow lights) is necessary.
Nutrition solution for hydroponics and general soil fertilizers contain nitrogen (N), phosphorus (P) and potassium (K), which are indispensable substances for plants. We call them "three elements of fertilizer". . The difference between the two fertilizers is that the hydroponic nutrient solution also has many trace elements that plants need. Hydroponic fertilizers are directly dissolved in water without fermentation and are prepared by dissociation into components that can be absorbed by plants.
The difference between hydroponics and organic fertilizer
In contrast, organic fertilizers have ion-type microorganisms that plants can absorb, and decompose nutrients to make it easier for plants to absorb. In recent years there have been some excellent organic fertilizers on the market with refined formulations suitable for hydroponic cultivation.
These important substances can provide normal growth of plants, including calcium, magnesium, sulfur, boron, copper, iron, sulfur, manganese, zinc and so on. If it is insufficient, it will also cause specific physiological dysfunction. If the conditions are good, at best, the production will not be optimal. In the worst case, the plant will die. Therefore, in hydroponic cultivation, the composition of the nutrient solution can be adjusted according to the needs of various crops to provide complete nutrients.
Our hydroponic nutrient solution is formulated according to the law of the nutrient demand of vegetables in their natural growth state, which can provide nutrients for the growth of vegetables more accurately, more reasonably and more effectively. At the same time, no matter whether it is grown in soil or grown in water, vegetables absorb the same chemical ions as nutrients. Even organic fertilizers must be converted into ionic forms before they can be absorbed by vegetables. So there is no need to worry about the low nutritional value of hydroponic vegetables.
