Vegetables that can be hydroponically cultivated are generally mainly leafy vegetables, such as lettuce and water spinach, and of course some fruit vegetables can also be used, such as cucumbers and tomatoes. And their breeding methods are similar, mainly placing the roots of the vegetables in the nutrient solution. And this nutrient solution will provide water, oxygen and other things for vegetables, and these vegetables rely on these nutrients to grow. Therefore, in this way, things such as land preparation, weeding and arable land are also reduced, a lot of workload is reduced, and labor and time are saved.
Hydroponic vegetables are usually grown in boxes with good water storage. There are common wooden boxes and large pots. A clean medium and large plastic foam box is suitable, and a floating board of suitable size is placed at the bottom of the foam box, which can not only store water, but also carry the importance of vegetables, and it is good to colonize vegetable roots. After all, whether it is building a hydroponic tank or preparing a nutrient solution, we all need to learn from scratch.
The upper and lower layers of the inner wall are designed with diversion grooves to allow the nutrient solution to flow fully so that the nutrient solution can be fully circulated; the arc surface is used as the bottom, and the nutrient solution is concentrated at the bottom of the arc when the nutrient solution film is used for hydroponics, so that many roots are exposed to the air to increase the number of roots. Breathable space allows plants to grow well; when used outdoors, the arc surface is used as the top surface. When it rains, the rainwater slides along the arc surface and will not be poured into the sink to affect the nutrient solution; the hydroponic leafy vegetable pipe can make most leafy vegetables production demand.
The characteristics of the leafy vegetable factory: it contains a variety of nutrients required by plants, without fertilization, and has strong water retention and water absorption; the appearance is pleasing to the eye and brings ideal visual effects; using the leafy vegetable factory to cultivate flowers and plants, You can directly observe the process of plant growth, which will help stimulate children's interest in observing nature and cultivate their sentiments.
Supplement or replace the nutrient solution in the hydroponics of the leafy vegetable plant? This depends on the water consumption rate of the plants. If the weather is dry and the plants are larger, the nutrient solution should be replenished once in about 15-20 days, and an appropriate amount of nutrient solution can be added when replenishing. Don't add too much nutrient solution, just add about 1/3-1/2 of the depth of the container. How long does the concentrated nutrient solution for hydroponic flowers last? What should I pay attention to when storing? The validity period of the concentrated solution of hydroponic flowers is almost unlimited, but generally do not use those with a storage period of more than 5 years. The concentrated nutrient solution should be stored as far as possible away from light, and should not be placed in the reach of children.
Nutrient solution is generally not prepared by yourself, because hydroponic vegetables on the balcony of the home need less nutrient solution, but choose to buy it from a gardening company. There are two kinds of nutrient solutions sold by horticultural companies, one is solid nutrient solution and the other is liquid nutrient solution stock solution, which can be prepared by adding water according to the product instructions. The water pump is the driving force for the circulating flow of nutrient solution, and gardening companies generally sell it with a complete set of devices.

When connecting the high-power LED substrate and the heat sink, please ensure that the two contact surfaces are smooth and in good contact to enhance the bonding of the two contact surfaces. The hydroponic vegetable LED plant growth light is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. According to the type, it belongs to the generation of plant fill light lamps! It is recommended to apply a layer of thermal grease on the bottom of the LED substrate or on the surface of the heat sink, apply evenly and properly, and then press and fix it with screws. connecting party.

Therefore, the leafy vegetable factory can automatically control the amount of acid-base or supplementary elements, but this cycle cannot be continued without interruption. The method is to supply enough oxygen to the roots of the plants. When the plants are transpiring vigorously, the concentration of the culture solution increases. At this time, some water needs to be added. The key to the success of the leafy vegetable factory is to manage the nutrient solution used to make it conform to the nutritional state of the plant. needs. The composition of the nutrient solution in the leafy vegetable factory is easy to control and can be adjusted. It can be carried out in places where the light temperature is suitable and there is no soil, such as desert beaches and desert islands, as long as there is a large amount of fresh water supply.
