Chapter 31
Compared with soil cultivation, hydroponics is more tedious and more expensive, and the growth is not as fast and lush as that of soil cultivation. The fact that soil cultivation is still the method used for large-scale planting demonstrates its superiority.
Indoor hydroponics has an overwhelming advantage: it is clean and intuitive, and with the assistance of smart instruments, it takes less time. It can immediately identify which plants are growing abnormally and directly observe the growth of fruits and vegetables in detail.
Just like this time, the rotten lettuce was able to be separated from the others quickly, otherwise the bacteria and contamination media would penetrate into other tanks and cause further losses.
Chao Youqian had no concrete evidence that the red moon caused root rot in vegetables, and searching for keywords yielded no further results, so the idea gradually faded. However, he still moved the smart hydroponic rack further away from the window.
Since buying several sets of electrical appliance repair and replacement equipment, they have been checking the home's fresh air, air conditioning, dehumidifier, air purifier, etc. every one or two weeks.
Whether it is central air conditioning or fresh air system, the pipes are very long. Over the years, thick dirt will form. Not only will bacteria enter the human body through air circulation, but they are also difficult to clean. Therefore, they will use special high-pressure machines to clean them every month.
The air quality outside this week was not optimistic. Lang Xin and Chao Youqian wore masks and gloves and removed the filter, and found a lot of black and gray dirt, and even a few insects mixed in it. However, because of the filter, the house has been very clean and dust-free.
The filter of the air purifier in the house, which serves as an auxiliary function, is also a bit dirty. This is on the 26th floor and the windows are rarely opened. H City has good greenery and there is little traffic on the road due to the epidemic. It is really strange that the air is dirty even though there is so much moisture in it.
Now that life has basically returned to normal, although express delivery is still not allowed into the community, logistics and other things are very smooth. The filter wears out faster than they expected. Because it is a high-efficiency filter and cannot be cleaned, it can only be replaced. They ordered a large box of filters as a backup.
After the replacement, the fresh air system was turned on again. The air quality was not obvious to the human body, but it did bring a refreshing feeling psychologically.
Recently, I have seen some self-media reports that the number of pneumonia patients has increased significantly and respiratory diseases are prevalent, which may be related to abnormal air quality.
This year, all the interns in Lang Xin's work group switched to online internships. One of them happened to be locked up in a school in S City, so he started his summer internship in the dormitory.
In the locked-down city of S, this group of students was stuck at a time when their final exams were over but they still had two weeks to stay. The stay-at-home order was issued too suddenly, forcing at least one-third of the students to stay in school.
Because there were cases on campus at the time, the dormitory was immediately closed. Fortunately, his other roommates had gone home early, otherwise it would have been inconvenient for him to do his internship.
When chatting in their work group, the intern said that the X virus epidemic in City S is now generally under control, and all major universities have issued notices for students to return home in an orderly manner, and many alumni are applying to go home.
The school has limited staff and cannot always deliver meals to students' homes when the dormitories are closed. There are also various management issues. It cannot always detain students during graduation season, and many seniors are locked up in school.
As soon as the policy was announced, arguments ensued. Some people were extremely afraid of Virus X and felt that the movement of college students out of the city would increase the risk of infection, so it was irrational to send them out now.
Some people are also worried about the quarantine issue after returning home, whether to pay for it themselves or how to calculate it. College students generally have no source of income, and the cost of at least 14 days of quarantine is not cheap.
Some extreme people even say that people who return to their hometowns are selfish. The smaller the place, the more likely such remarks are made. There are also extreme reactions like the one in the village where the road was blocked and guarded by an old man with a knife.
The intern said sadly that he was studying in S City and his home was in another city that was under lockdown. He couldn't leave even if he wanted to, so he stayed in the dormitory every day and couldn't go out. Although the quarantine meals were free, they only consisted of a few items, and he hadn't had a Coke for a month.
Everyone in the group also works online, but most of them live in City B. They comforted the intern by saying that other residents in City S still have to scramble for food and daily necessities, and students don’t have to worry about their own life security. They can only endure it for the time being because there are few varieties of food. They believe that the lockdown will be gradually lifted after there are no cases on campus.
Looking at the chat history forwarded by Lang Xin, Chao Youqian ran to open a can of iced cola, poured it into the glacier cup with a sense of ritual, and added half a cup of ice and two slices of fresh lemon.
There was also related news from B University, which he had just left. Chao Youqian’s counselor’s circle of friends posted two or three posts about the school’s epidemic policies every day, as well as several notices criticizing students who did not comply with the epidemic prevention policies.
After taking a sip of ice-cold cola, Chao Youqian looked at the photos of his classmates in his circle of friends who used to travel all over the world and returned to their daily lives.
He posted pictures of his three meals a day, and occasionally complained about not being able to go out because he could hear the sound of children being beaten in the community clearly, and conflicts were easily caused by poor sound insulation between the floors above and below.
A classmate living in a locked-down city posts a screenshot every day of a food delivery platform shutting down and unable to get a KFC meal, accompanied by a bleak caption. Chao Youqian would have believed it if he hadn't known he lived in a single-family house in the suburbs of S City. He left a dog-head emoji under the post, and this brother, Zhao Tian, unleashed a barrage of complaints as if he had found a tree hole:
[Brother Qian, don't believe me! My family is a murderous mess. We can't even order takeout in the suburbs. We have ingredients, but none of them are edible! The cook is quarantined at home and can't leave. My house is a murder scene, filled with the smell of burnt food.]
[You're awesome, Lang Ge is so kind! I wish I could fly to H City and be your housekeeper, cleaning and eating one meal a day would be fine. Please take me in!]
He sneered at Youqian. Zhao Tian was the one who liked to stir up trouble and pair him and Lang Xin together. This unreliable person started to talk nonsense again.
[Go away, go look up a recipe yourself, or buy a food processor. How can a living person be killed by food?]
Zhao Tian still didn't give up and said something stupid, "I'm not here to destroy you, I'm here to join you."
Chao Youqian's slender, white fingers tapped cruelly on the screen, replying that he had taken a screenshot and was about to forward it to Lang Xin. His friends somehow felt a sense of awe towards Lang Xin, and even the most outgoing ones didn't dare to shout in his presence.
Sure enough, the other person immediately sent a tearful cat emoji. Zhao Tian didn't want to interact with Lang Xin. Even Chao Youqian, who had become friends with him, had experienced Lang Xin's extremely low-pressure aura. He was a master of protecting his children. Although his family was based in Hong Kong, they were also well-known in mainland China. The games they played most often were all produced by Lang Xin's company. It seemed they had recently merged with a larger company, but given the impact of the X virus, it was still a good move.
