In recent days, Shanghai's pandemic prevention and control situation has been severe, and many residents have been locked at home and cannot go out. Some people have been quarantined at home for half a month or even more than a month because of the continuous emergence of positive cases in the community. How to eat fresh green vegetables has become a concern for everyone. As a super-large city with 25 million people, Shanghai's sudden shutdown has posed a huge challenge to logistics, and the distribution of materials has also lagged behind due to manpower problems. Therefore, many Shanghai residents joke about the fact that vegetables have become a luxury now.
To keep vegetables fresh, many people try hydroponics at home for the first time. Hydroponic garlic sprouts, hydroponic carrots, hydroponic Chinese cabbage; some people even plant potatoes on the balcony. Everyone uses all the resources around them to actively save themselves and keep the vegetables fresh as much as possible.
