1. What is hydroponic flower technology?
　　Hydroponic flowers refer to the cultivation technology of directly using water and nutrient solution to cultivate flowers, so as to achieve the purpose of family flower cultivation, and realize the effects of hygiene, environmental protection, and trouble-free.
2. How do hydroponic flowers survive the winter? Can ordinary flowers survive the winter safely?
　　They can survive the winter safely above 0℃ in the south, and they can survive the winter indoors in the north. They can survive the winter in ordinary greenhouses.
3. Is the production environment of hydroponic flowers a greenhouse?
　　They can be produced outdoors in the south and in greenhouses in the north. Since the production cycle of hydroponic flowers is short, they are generally sufficient. For slightly larger ones, they usually have their own flower bases and build their own greenhouses, which is very low in cost, and they start from small seedlings, so the cost is even lower.
4. How long can ornamental fish be raised in hydroponic flowers? How to deal with technical problems such as water changes?
　　Fish can be purchased locally. The nutrient solution does not have a great impact on fish, and the nutrient solution itself also provides some mineral nutrients. Under normal circumstances, depending on the variety, the length of the feeding time can meet the ornamental requirements.
5. Can the nutrient solution be used when it is changed from soil culture to hydroponic culture?
　　The nutrient solution can be used when switching from soil culture to hydroponics. If you are inexperienced, it is recommended to use half a dose of nutrient solution first, that is, dilute the original 200-fold concentrate 400 times before use (or dilute the original 400-fold concentrate 800 times before use), and use a dose of nutrient solution about a month later. Of course, soil-cultured flowers can also use nutrient solution.
6. What kind of technology does hydroponic flower technology refer to? Can flowers and fish be raised together?
　　It is mainly about the domestication technology and precautions of soil-cultured flowers to hydroponic flowers, which can completely achieve flower and fish co-cultivation.

7. Can hydroponics only cultivate certain specific flower species or can it be applied to all popular flowers?
Both specific flower species and popular flowers can be cultivated hydroponically.
8. After the seedlings leave the soil, do all seedlings need the same amount of nutrient solution during the cultivation process in the nutrient solution?
　　Strictly speaking, they are not the same, but in order to simplify the production steps, they are generally regarded as the same, and not much nutrient solution will be wasted. Moreover, the cost of nutrient solution is not high, so it is not important to use the amount of nutrient solution, mainly to save labor costs.
9. Does the addition of flowers, nutrient solution and fish farming conflict?
　　Not at all, the three can coexist peacefully. This is also one of the keys to the nutrient solution formula.
10. Should the seedlings be cultivated in the soil for a period of time before being cultivated in water?
　　It can be directly cultivated hydroponically, or soil cultivation can be converted to hydroponics.
11. Can the roots of flowers fully absorb water by supporting the flowers with a planting basket?
　　Yes, just make sure there is water vapor at the bottom of the planting basket.
12. What should I pay attention to when and how often to change the water?
　　Change it every 20 to 40 days. We provide technical support.
13. If you use ceramsite, colored stones, glass balls, etc. for cultivation, can you use nutrient solution?
　　Yes, it can be used, it will not affect the growth of flowers, but you can't enjoy the roots and fish.
14. Do all kinds of seedlings use the same nutrient solution, how to control the concentration?
　　You can use the same nutrient solution (universal) or a special one. Strictly speaking, you need to use instruments to judge when to add or replace the nutrient solution, but you can also rely on experience. Generally, the nutrient solution is replaced every 20 to 40 days.
15. How long does it take for a seedling to become a finished product?
　　The growth rate of hydroponics is generally 50 to 100% faster than that of soil cultivation. Of course, if the temperature is high and the humidity is high, it will be faster. But you can directly buy finished seedlings to acclimate hydroponics. Generally, they can be sold within 5 to 20 days, and they may even be sold within 5 days, but they may be more unstable. Therefore, when switching from soil cultivation to hydroponics, it is recommended to wait for 15 days of hydroponics and wait for new roots to grow before selling. Such hydroponic flowers are more stable, more responsible to the end customers, and less after-sales service.
16. Can nutrient solutions for any plants be mixed?
　　The universal nutrient solution is suitable for all kinds of plants. When using, first fill the hydroponic pot with enough tap water, then pour a bottle cap of nutrient solution into the pot and stir evenly. 

17. How do hydroponic flowers survive the winter? Can ordinary flowers survive the winter safely?
1 Generally, the flowers selected for hydroponic flowers are mostly foliage flowers and foliage and flower flowers that are slightly shade-tolerant and cold-resistant. Therefore, most hydroponic flowers can survive the winter safely.
2 Pay attention to heat preservation in winter. Flowers should be placed in windows where sunlight can directly shine (avoid cold air outlets from glass windows) as much as possible. At the same time, you can cover the flowers with transparent plastic bags, and open a few small holes in the plastic bags for ventilation.

18. Does the nutrient solution harm ornamental fish?
The nutrient solution used for hydroponic flowers is inorganic minerals that are harmless to fish. There is no problem for fish to survive in the nutrient solution for a long time. Fish and roots in the water have a mutually reinforcing effect: due to metabolism, adsorption and algae activity, the root system will produce and cover a layer of organic foreign matter on the surface, which provides food for fish; fish clean up root attachments, and their small amount of excrement also provides nutrients for plants, which is beneficial to plant growth.
Don't raise too many fish, 1-2 small goldfish are enough. Too many will easily spoil the water, and fish will also easily float due to lack of oxygen. If there is a power supply next to the flowers, it is best to use a 3-watt micro air pump in summer. The power consumption is very small, but it saves the trouble of frequent water changes and is more ornamental.
19. Can hydroponics only cultivate certain specific flower species or can it be applied to popular flowers? Both
specific flower species and popular flowers can be hydroponically cultivated.
20. If ceramsite, colored stones, glass balls, etc. are used for cultivation, can nutrient solution be used?
Yes, it can be used, it will not affect the growth of flowers, but you can't enjoy the roots and fish.
21. How to change water?
When the temperature is around 120-25℃, change the water every 20-30 days. When the temperature is low, the water change time can be appropriately extended, and when the temperature is high, it should be shortened.
2 When fish are kept together, water should be changed frequently. It is best to buy a micro air pump of about 3 watts with very low power consumption. Proper aeration can greatly extend the water change time (generally, the water can be changed once every 1-2 months).
3 Tap water can be used, but it is best to leave it for one to two days. The temperature difference between the original water and the new water should not be too large. Generally, 5 ml of A and B nutrient solution are added to every 3 liters of water. If there is no measuring instrument, a 500 ml mineral water bottle can be used instead, and 2 bottles are 1 liter.
4 Due to the adsorption, metabolism and algae activities of the root system, foreign matter will be covered on the surface of the root system after a period of time. When changing the water, it can be carefully rinsed and cleaned with water. If there are old and dead roots, they should be removed when changing the water.
5 There should not be too much water in the bottle. It is appropriate to immerse about 2/3 of the root length in the water.
6 In winter and midsummer, the concentration of nutrient solution should be reduced (usually 1/3-1/2 of the normal concentration).
22. What are the requirements for temperature and lighting for hydroponic flowers?

1 Generally, most of the flowers selected for hydroponic flowers are slightly shade-tolerant and cold-tolerant foliage flowers and foliage and flower-leaf ornamental flowers. These flowers like warm and humid conditions, are slightly shade-tolerant, avoid high temperature and dry heat in summer, and avoid too low temperatures in winter.
2 "Hydroponics" only changes the cultivation form, but does not change its growth habits and the required environmental factors. In summer, it is best to place hydroponic flowers in a bright, slightly high humidity, cooler, and well-ventilated environment. Avoid strong direct sunlight, but do not shade them too much, so as not to hinder the photosynthesis of flowers and weaken their growth.
3 Generally, the room temperature is above 5°C. As long as you pay attention to heat preservation, most varieties of hydroponic flowers can safely overwinter, but a few varieties, such as Anthurium, Fortune Tree, Brazilian Wood, Golden Queen, Hulk, etc., have difficulty overwintering. 23.
Can hydroponic flowers be placed in air-conditioned rooms? Hydroponic
flowers can be placed in air-conditioned rooms. However, hydroponic flowers should not be placed directly opposite the air outlet of the air conditioner, as excessive wind speed will damage the branches and leaves. Flowers can be placed farther away from the air outlet of the air conditioner. There will be no problem if the temperature difference between day and night is not too big.
