When it comes to vegetables, most people's first impression is that they grow from the soil. When picking vegetables at the market, you can even see the roots still covered in soil.
But have you ever eaten vegetables grown in water?
That's right, vegetables can grow in water! Most of the root system of hydroponic vegetables grows in nutrient solution, and the roots obtain the necessary nutrients through the nutrient solution and water.
Hydroponic vegetables are cleaner, more hygienic, and more environmentally friendly than soil-cultivated vegetables. It is also a particularly advocated vegetable cultivation method in home vegetable planting. In fact, if you look closely at the supermarket vegetable section, you can also find hydroponic vegetables.
What are the advantages of hydroponic vegetables?
Green and pollution-free
Due to the rapid increase in population and the rapid development of industry, soil pollution has become increasingly serious. Pollutants absorbed and accumulated from the soil by vegetables and fruits grown in soil often affect human health through the food chain.
Hydroponic vegetables are vegetables that are planted directly in water, isolated from the soil, and are not affected by soil pollution. Not only that, but hydroponic vegetables also do not have pest pollution during their growth, and can be completely pesticide-free, making them truly healthy, pollution-free, and pure vegetables.
Because the nutrient supply is sufficient and timely, and the growth environment is controllable, various external environmental conditions for vegetable growth meet or approach their optimal growth requirements. Therefore, the growth rate of hydroponic vegetables is faster than that of soil cultivation.
However, hydroponic vegetables do not have lower quality due to their faster growth rate. On the contrary, due to the sufficient and timely supply of nutrients and good environmental control, the efficiency of plant photosynthesis is high, and the amount of nutrients synthesized is more and faster than that of soil cultivation, and the content of VC and other nutrients is significantly improved.
Hydroponics has better controllability than soil cultivation. The content of nitrates in vegetables can be controlled by adjusting the supply amount and time of nitrates in the nutrient solution, which is impossible to achieve in soil cultivation. The nitrate content of hydroponic vegetables is low, only a few tens of one percent of the national standard.
Excellent taste
Soil cultivation has stresses or damage such as drought, waterlogging, nutrient imbalance, insect bites, and pathogenic microbial infection, which will inevitably induce plants to secrete many secondary metabolites such as polyphenols, quinones, and sesquiterpenes to resist these stresses. Over time, a large number of secondary metabolites will accumulate in vegetables, and most of these secondary metabolites are colored or bitter, which will affect the appearance and taste of vegetables.
In contrast, the various conditions for the growth of hydroponic vegetables are more suitable or closer to the ideal state, and plants will not accumulate too many secondary metabolites. Therefore, hydroponic vegetables will have a better taste.
With the improvement of people's living standards and changes in dietary habits, green food is generally favored by people. People are no longer satisfied with the supply quantity of vegetables, but also pay more attention to the appearance, quality, and food safety of vegetables.
However, due to the higher production cost of hydroponic vegetables, the market price is several times that of ordinary vegetables. Coupled with the lack of understanding of hydroponic technology, many consumers are discouraged.
Actually, you can try simple hydroponic vegetables at home! The roots of vegetables such as onions, cabbage, coriander, celery, carrots, and lettuce can be directly used for hydroponics.
Prepare a bottle, pour in nutrient solution, and then put in the roots, and you can start simple hydroponic vegetable growing!
