Hello everyone! I’m Shohei.
Plant factories are attracting attention as “the future of agriculture.”
They have been increasing in prominence in recent years due to their ability to produce vegetables regardless of the weather.
And supporting these plant factories are the staff working in plant factories.
I have been working on the front lines of the field for over 10 years as a plant factory manager and as a manager who trains other managers.
In this article, I will explain the necessary qualifications, skills, and job duties of a plant factory manager in an easy-to-understand manner for those interested in plant factories.
By the way, for those who are wondering what the merits and demerits of plant factories are in the first place, please read the following article as well.

What kind of job is a plant factory manager?
As the name suggests, a plant factory manager is someone who manages the overall operation of the plant factory. They handle a wide range of tasks centered on crop management and on-site management, and they oversee the entire factory.
Personally, I want many people to know about plant factories.
So, I’m writing about my experiences on this site, and I’ve also written articles like the following:
Reading them together will give you a more accurate understanding of the work involved in a plant factory.

Now, what kind of jobs are there in a plant factory?
I will explain the specific job duties.
[Plant Factory Jobs] 1. Crop Management

Plant factories are truly a “paradise” for plants, unaffected by sunlight or weather. However, creating this paradise depends on the skills of the plant factory manager.
I entered the industry as a complete beginner.
I had no experience in plant factories, agriculture, or production management. It was tough at first because there was so much knowledge required, and I’m still learning.
For example…
- Production Planning and Execution:
Plan when, which varieties, and on what scale to produce throughout the year. Develop and execute detailed plans while considering market demand, sales prices, cultivation periods, and the capacity of the plant factory. - Environmental Control: Controlling the growing environment is the lifeline of a plant factory. Maintain optimal conditions for plant growth, including temperature, humidity, light, CO2 concentration, and wind speed. Daily observation of the growing conditions and data-based analysis, as well as experience-based judgment, are required.
- Point: It is especially important to understand “why” that environmental setting is optimal. For example, you need to understand the optimal light wavelengths and irradiation times to promote plant photosynthesis, and how temperature and humidity affect plant growth rates and morphology, based on scientific evidence.
- Nutrient Solution Management: In plant factories that use hydroponics, nutrient solution management, which is the source of nutrition for plants, is very important. Regularly measure the concentration and pH of the nutrient solution and adjust it appropriately according to the growth stage of the plants. It is important to maintain the balance of essential nutrients such as nitrate nitrogen, phosphoric acid, and potassium, and also to pay attention to the lack of micronutrients such as calcium, magnesium, and iron.
- Point: Experience-based intuition is also important for nutrient solution management. Carefully observe the color and shape of the plant’s leaves and the growth speed, and finely adjust the composition of the nutrient solution if necessary. This is where the “skills of a master” gained from many years of experience come into play.
- Hygiene Management: In a plant factory, if pests or diseases occur, they can cause devastating damage to the entire factory. Therefore, thorough hygiene management is required. In addition to thoroughly cleaning and disinfecting the factory, it is also important to educate employees about hygiene. It is also necessary to take measures to prevent pests from entering.
- Point: Early detection and countermeasures in the event of an abnormality are important. Through daily observation, an eye for spotting even slight changes in plants is required. Also, in the unlikely event that a disease or pest occurs, you need to be familiar with appropriate measures to minimize the damage.
When you hear these stories, you might think, “That sounds difficult…”

In addition to taking safety measures to prevent industrial accidents, we aim to create a comfortable workplace environment where employees feel motivated and can maximize their abilities.
- Point: Employee satisfaction has a significant impact on productivity and quality improvement. It is important to increase employee motivation by creating a comfortable working environment.
- Quality Control: Vegetables produced in plant factories must meet strict quality standards. Therefore, it is necessary to thoroughly check the quality of vegetables before shipping and establish a strict management system that does not ship those that do not meet the standards.
- Point: Quality control is very important to maintain the reliability of plant factories. An attitude of tackling quality control with a sense of responsibility is required so that consumers can eat with peace of mind.
Even though automation is progressing in plant factories, there is still a lot of work that requires human hands.
In large-scale sites, it is not uncommon for there to be more than 100 employees.
If you are skilled at cooperating and collaborating with others, you should be able to play an active role on site.
