Traditional Chinese medicine believes that legumes have a sweet and flat taste, and have the effects of dissipating dampness and tonifying the spleen, regulating the digestive system, tonifying the kidneys and stopping diarrhea, and nourishing qi and promoting fluid production. They are particularly suitable for people with weak spleen and stomach. Modern nutritional data shows that beans are rich in protein and carotenoids, with high nutritional value, making them known as the "meat of vegetables".
The nutritional value of beans is very rich, and eating them regularly is very beneficial for the human body. Summer has slowly arrived, and the weather has become very hot. Eating more beans in summer can effectively relieve heat and have a green mouth effect. Some people want to plant beans indoors through hydroponic methods. Is this idea reliable?
Certainly. Beans are planted in hydroponic culture, where their roots are more free and can grow faster and better. Below, we introduce a column system hydroponic method for planting beans.
Generally speaking, beans and kidney beans are easy to grow in hydroponic systems. Choose a hydroponic tower system that can be planted indoors throughout the year. If you want to grow beans on a large scale, or if the types of beans you plant are different, the selection of hydroponic planting equipment will also vary. The most commonly used hydroponic equipment for cultivating beans for beginners is the hydroponic tower system.
Precautions for hydroponic beans:
1. Beans sprout quickly, usually in less than 2 weeks, sometimes only taking 3 to 8 days. The germination time also varies depending on the variety of legumes, seed quality, and environmental factors.
2. Leguminous plants like ample sunlight. Excessive or insufficient light can cause problems, and leguminous plants should not have more than 12-13 hours of light exposure. The hydroponic tower system has LED plant growth lights that can provide light for crops at any time. In addition, the hydroponic tower system is an automated planting equipment that does not require too much effort on hydroponic planting.
3. The growth of legumes requires nutrients, and we need to ensure that sufficient nutrient solution is delivered to the beans during hydroponic cultivation to provide nutrients.
Once everything is ready for the growth of legumes, we can wait for the harvest. Usually, hydroponic legumes grow faster than traditional legumes, and can be harvested in about 60 days. However, the harvest time may vary depending on factors such as variety and environment.
Here is a note for everyone to be aware that raw beans can cause poisoning. When people eat raw beans, the toxin has a strong stimulating effect on the gastrointestinal tract. Mild cases may feel abdominal discomfort, while severe cases may experience poisoning symptoms such as vomiting and diarrhea, especially in children. Although these two substances in beans are toxic to the human body, they have their own characteristics and weaknesses, that is, they are not resistant to high temperatures. Therefore, whether it's parents at home or the chef in the daycare center, when cooking beans for children, it's important to heat and cook them thoroughly to ensure that the beans are fully cooked, and harmful substances will decompose into non-toxic substances.
