All of them had experience in making salad containers.
He was one of the best hydroponic cultivation technicians in the country.
A simple understanding was required before creating a vertical cultivation facility.
Although it was a verification task, it was also a task to create a new hydroponic cultivation facility.
All of them have experience building hydroponics, but this is their first vertical cultivation.
I designed a vertical cultivation facility with Min Yo-han and Lee Jang-woo.
I was in charge of explaining to the engineers.
“The hydroponic plant we will be building from now on is different from the one we’ve made so far. The main difference is that the roots of the crop do not come into contact with the water.”
“The roots don’t touch the water?”
Lee Dong-chun opened his eyes and asked.
In a conventional salad container, the roots of the crop were submerged in water. This is because it is a structure in which water and nutrients circulate in one tube.

Oxygen was supplied via an air pump.
“In this facility, the roots of crops do not come into contact with water.”
“Then how do you give them water and nutrients?”
“Water and elixirs will be sprayed.”
“Spray?”
“It’s a method of spraying with a nozzle.”
I turned on the project screen. The prepared image came out.
It was seen that the roots of the crop were exposed in the air. There was a nozzle device that sprayed water and nutrients under the roots.
“Water and elixirs are sprayed like mist from the nozzle.”
Lee Dong-chun and the other engineers tilted their heads as they looked at the atomizer.
I don’t understand why the roots were exposed in the air.
“There is nothing wrong with the roots of crops being exposed outside. On the contrary, there is one advantage.”
“Is it an advantage?”
Lee Dong-chun asked with curious eyes.
“There is no need to supply oxygen with an air pump.”
When talking about the air pump, Lee Dong-chun nodded.
He seemed to understand.
I explained in detail for other engineers.
Crops breathe through root hairs. Just because a crop is buried in the soil doesn’t mean it doesn’t breathe.
There are small gaps between the grains of soil. Air enters through them.
The hydroponic cultivation facility that has been produced so far has a structure in which the roots of crops are submerged in water.
to let u know that i been through a lot then i been going non stop with this practice for nothing
Moisture and nutrients were not a problem, but there were no breathing holes.
Because the water blocked the pores. Therefore, it was a method of supplying oxygen using an air pump.
There is no need to use an air pump by spraying water and elixirs using a nozzle.
The roots of the crop were exposed to the air, allowing them to breathe air into the atmosphere.
“It’s kind of like a bidet.”
Lee Dong-chun said with a smile. People around him were also fed up with his words.
“As I said, it has a similar structure to a bidet. The difference from a bidet is that you have to spray continuously to keep the roots from drying out.”
Everyone burst into laughter when I said that I was constantly spraying.
It was said like a joke, but Lee Dong-chun understood it correctly.
Just as water is sprayed on a person’s buttocks, water and nutrients are sprayed on the roots of crops as well.
It was also the reason why vertical cultivation was possible.
This is because the thin nozzle is connected to the hydroponic plant like a blood vessel.
It is a tube as thin as a human blood vessel. It was not affected by water pressure and water load.
Because the light pipes were closely connected, the facilities could be stacked high.
After the explanation, it is time to go back to our seats.
Lee Jang-woo approached me.
“Now, our representative, look at something else. This is where I will take responsibility.”
“Are you okay without me?”
“Mr. John is there, and I am there, so there is no problem. You have a lot of other things.”
Then Min Yo-han appeared.
“As Jang-woo said, please leave this to us.”
to let u know that i been through a lot then i been going non stop with this practice for nothing
Min Yo-han also said with a confident face.
“Then I’ll leave it to you two.”
As Lee Jang-woo said, there were many things to be dealt with.

I went straight to the office.
There was work to be done regarding patents.
Han Gi-tak was waiting for me.
“Is the creation of the verification facility going well?”
“Yes, it will be completed as soon as possible.”
“It is expected.”
“By the way, did you know anything about patents?”
“I was talking to a patent attorney and reviewing the documents.”
“Is there anything special about it?”
“I don’t think it would be difficult to obtain a domestic patent, but an international patent is a bit tricky, isn’t it?”
Before I entrusted the patent to Han Gi-tak, I also looked into it.
International patents are more difficult than expected.
There is a system called the PCT (Patent Cooperation Treaty).
It is a system to more easily obtain patents between countries.
It is a system in which patents are recognized by designating the country in which you wish to apply to the patent office and submitting an international application.
International applications may be submitted to countries that are signatory to the Patent Cooperation Treaty.
But international patenting is not as simple as it sounds. The process for obtaining a patent is difficult. It took a long time.

Of course, if you met a competent patent attorney, the process and time could be shortened.
“Please don’t waste your money on this. Patent attorneys also hire the best.”
Han Gi-tak thought for a moment. He was also the housewife who managed the finances of the Jirisan farmers.
Be careful about spending your money.
“I know how important this is, too. As the representative said, I will spare no expense.”
Han Gi-tak said in a stern tone.
It’s time to get up and organize the paperwork.
Han Ki-tak asked.
“Then, are you going to start a large-scale funding process now?”
“Yes, I have to go in.”
“Are we supposed to finish the verification of vertical cultivation?”
“I’m going to start promoting it before the verification is over.”
“It’s publicity… … . What else are you planning?
“I want to reveal it on TV.”

The next day, we headed to Yeouido.

On the way to the radio station.
I had something to give to PD Choi Min-seong. This is the video camera he gave me.
The video camera captured the long journey in Antarctica.
From the process of installing salad containers in Antarctica to the installation of bean sprouts growers and hydroponics facilities at the Chilean base, not one was left out.
The angles weren’t as varied as the pros, but I liked it.
It is because it contains all the screens you want without omission.
There were also members of the South Pole Korean base.
This is a video of a scene from playing table tennis at the Antarctic Olympics and a dinner with pork belly. It was nice to see them again.
All were filmed with the consent of the crew. They, too, were expecting their faces to appear through the broadcast.
He said he wanted to show his family that he was in good health.
Arriving in Yeouido, I entered the lobby of the broadcasting station.
A large promotional placard was hung in the lobby.
I doubted my eyes for a moment.
I was promoting a program I knew well.
‘Farmers are hope.’
It was also a show I appeared on.
I heard that ‘Farmer is Hope’ steadily rose in ratings.

On the way home from the airport, Han Gi-tak said as a joke.
It is said that the popularity of the program has been skyrocketing, starting with sprouted ginseng.
I didn’t think the placards would be hung up in the lobby of the broadcasting station.
There was a familiar face on the promotional placard.
Hwang Yu-shin, a master of dried persimmons, and Im Si-baek, a master of green tea.
Although they had a smaller face, there was also Mr. Moon-ho Park of the Beekeeping Association.
These are the people who asked to appear as substitutes. Now he looked like a full-fledged broadcaster.
I went into the conference room.
PD Choi Min-seong and writer Ko Ae-joo were waiting for me.
Go Ae-ju got up from her seat.
“Long time no see. Did you have a good trip to Antarctica?”
“Yes, thanks to you, I went well.”
PD Choi Min-seong also reached out and asked for a handshake.
“You suffered.”
It’s time to sit down.
PD Choi Min-seong was looking at my bag. His eyes are looking for the video camera he has entrusted to him.
“Are you looking for this?”
I took the video camera out of my bag.
PD Choi Min-seong looked at the camera with an excited face.
“Did you have any difficulties while filming?”
“It wasn’t difficult because you were so well informed.”
“If it’s not rude, can I check it for a moment?”
PD Choi Min-seong looked at the writer Ko Ae-joo and asked.
“Sure. Please check it out.”
“Then excuse me for a moment.”
PD Choi Min-seong went out with a video camera.
Go Ae Joo sighed and said.
“When you came with me, you promised to check after the meeting. Deokmyung, please understand.”
“I think PD Choi Min-seong waited more anxiously for the camera than me.”
Go Ae Joo smiled and nodded her head.
“I heard that the broadcast went well even while I was away.”
“I think it worked well because Deok-myung laid the foundation well.”
It reminded me of going to the cast with her.
It felt like a long time ago.
It is a pleasant memory.
“A lot of people are curious about Mr. Deokmyeong’s news.”
“My news?”
“Because articles are posted on the audience’s bulletin board every day. What happened to the farmer who went to Antarctica?”
“okay?”
Good timing. Now is the perfect opportunity to promote the funding of Jirisan farmers.
“Since the Antarctic work is over, do we have to broadcast again?”
“You probably won’t be able to do it the way you did back then.”
“Are you very busy?”
“We are planning to build a large-scale hydroponics facility in the future.”
“That’s too bad. Still, will you tell the viewers the story of Antarctica?”
“Sure. It’s also a video I shot with my own hands.”
“Tell me about your future plans on the show.”
“If you give me a chance, I will.”
Writer Ko Ae-joo made a satisfied expression.
Then the door swung open.
It was PD Choi Min-seong.
He was holding a video camera in his hand.
“Mr. Deokmyeong, this broadcast should go to a special feature!”
two events
PD Choi Min-seong seemed to be satisfied with the Antarctic video.
It’s just not satisfactory.
“Mr. Deokmyeong, I think you will do well in broadcasting.”
He said it with a serious face, not a joke.
“It’s not me who broadcasts, but PD Choi Min-sung is doing better.”
Writer Ko Ae-joo turned to PD Choi Min-seong. I’m curious about what level you’re even talking about.
“Is it that good?”
“The writer will know when he sees the screen. It’s at a level that could be aired as a special feature. Of course, it will need some editing.”
“I’m curious. I saw PD Choi say things like that.”
Writer Ko Ae-ju looked at me and said.
“PD-nim, you’re showing it too much~ Are you exaggerating?”
“It is an exaggeration, not an exaggeration at all. By the way, would you like to appear in this Antarctic episode? Deokmyung must appear.”
PD Choi Min-seong said in a pleading tone.
“Of course, it’s also a video I shot.”
“thank you. We will schedule a recording soon. We will contact you then.”
“I guess I’m not the only one appearing, right?”
“Is it possible? I will be appearing together with Minseo Geum.”
I nodded my head lightly.
A picture was drawn approx. It will be broadcast while watching the installation of salad containers in Antarctica.
It is the moment when you are about to return to Hadong after finishing work in Yeouido.
I got a call from Han Gi-tak.
an excited voice
“Deokmyeong-ah, it’s big news.”
“What news?”
“There is news that industrial plasticizer ingredients have been detected in imported tapioca.”
It is news that 32ppm of industrial maleic acid was detected in tapioca used in bubble tea.
to let u know that i been through a lot then i been going non stop with this practice for nothing
Maleic acid is a chemical that softens plastics. Excessive doses may cause kidney dysfunction.
The company in question is a Taiwanese bubble tea chain. It wasn’t just one or two places. Most Taiwanese companies selling bubble tea in Korea were caught.
The health authorities are said to have taken measures to recover the entire amount.
“And one more piece of news.”
“Is there any more news?”
“The news is that melamine has been detected in Chinese vegetables. Butterhead and Kaifira included.”
to let u know that i been through a lot then i been going non stop with this practice for nothing
Melamine, like maleic acid, is an industrial chemical.
It is mainly used as a raw material for plastics, dyes, and adhesives.
The reason for adding industrial chemicals to vegetables is simple. It is a kind of preservative.
It has the effect of looking fresh even after time passes.
“It’s kind of upsetting news.”
“I also got a little annoyed when I heard the news. Playing with people’s food. Anyway, that makes Jirisan farmers busy.”
Coincidentally, two incidents occurred. Both incidents affect the farmers of Jirisan Mountain.
