Facility Overview

About The Facility

We developed the small cultivation facility called "Veggie" for creating a highly profitable agricultural model. By introducing "Veggie", the agricultural problems can be solved such as "instability", "heavy labor" ,"high risk" etc. In addition,  you can start your farming in various places.

This small cultivation facility is suitable for farm workers, moreover it is also possible for the new entrants in agriculture industry to use it as a trial facility.

  • Minimum size:

    • About W6000 × D2500 × H2500

  • Basic Equipment:

    • Vertical Cultivation Tower, Irrigation Pump, Air Conditioning Equipment, Remote Monitoring System, Hydrophobic Control Equipment.

How We Work

"Veggie" is a vertical type hydroponics gardening system which cultivates vegetables in compact areas. Veggie's production capacity is 60 times larger than soil cultivation's. In addition, By installing air conditioning equipment, it is possible for "Veggie" to realize relatively stable and highly efficient cultivation.

Moreover, less labor is required from cultivation to harvesting because the water circulates automatically in "Veggie". Even people with little agricultural experience can cultivate with less burden.

Also, because of its small size, running cost can be suppressed by only using electricity for air-conditioning.  By connecting and partitioning it with others, it is possible to cultivate multiple crops with low risk of disease and insect pest spreading.

Visit Us

Green River Holdings Co., Ltd. is developing business with the aim of contributing to regional revitalization by providing products and services which combine renewable energy and agriculture.

"Veggie" which we are introducing this time is a small cultivation facility developed to promote growth in agriculture industry. We would like to solve the agricultural problem about instability and hope that a lot of people can use this facility.

We also operate our own farm which is a steel framed vinyl house, it also generates electricity by solar power.  We produce mini tomatoes and sell them to the market. Moreover, we demonstrate experiment about Vertical Type Hydroponics gardening in our farm.

We provide proposals not only about "Veggie" but also about steel framed vinyl house and solar power generation, we will continue to respond to various needs in the future.

Plant Factory

Agriculture > Production Related > Cultivation Environment > Plant Factory


Plant factory is a system that provides an artificial environment to suit the vegetables crops. By controlling environmental conditions such as light levels and temperature, it is possible to make vegetable production efficient and systematic.

Generally, The plant factory adopts solution culture, which provides natural light or artificial light as a light source to grow vegetables.In addition, Methods such as temperature and humidity control, CO2 starvation prevention by adding CO2 are also adopted. By utilizing these technologies, it is possible to plan the production of vegetables throughout the year.

Current Situation

Plant factory has been started and developed in Europe, mainly in the Netherlands. Currently, Plant factory has been turned into more advanced system that using technology to realize not only automatic production process but also manage the production data from environment improving such as humidly/temperature control to personnel management.

In Japan, Central Research institute of Hitachi, Ltd. first started on research and development of plant factory from the 1980s. And they succeeded in building the environment control system and putting it into practical use. In 2009, the Ministry of Agriculture, Forestry and Fisheries and the Ministry of Economy, Trade and Industry of Japan jointly launched the "Plant Factory Working Group under the Agriculture, Commerce and Industry Collaboration", and created the third boom of the plant factory. And now Japan has became the leader in artificial light type hydroponic technology field.

On the other hand, there are still many issues about operating the plant factory. Among 420 companies operating the plant factory, there are 75% of them are in deficit. The reason  may be that initial cost of plant installation and the operation cost such as maintenance cost and management cost are very expensive, but the unit price of vegetables is low, so it is difficult to make plant factory business profitable.

In recent years, there are some undertaking studies about the plant factory. For example, one study about LED high-speed cultivation method is undertaken jointly by Showa Denko and Shigyo Masayoshi professor from Yamaguchi University Faculty of Agriculture.

Technology Scheme

There are 2 types pf plant factories.

1. Sunlight type:

  • This type of plant factory is basically using the sunlight to grow vegetables in a semi-closed environment. It provides supports under the rainy weather and suppresses high temperature under the hot weather.

2. Artificial light type:

  • This type of plant factory is built in a fully closed environment under completely control by people. Without using any sunlight and, it grows vegetables by providing light by fluorescent lights and LED.

In Japan, the artificial light type is more widely adopted rather than the sunlight type. Because the artificial light type is easily to control, and on the other hand the sunlight type is easily influenced by the weather and day and night.

Merit & Strength

1. High-speed production, stable supply and high safety

  • It is possible to promote growth of vegetables by controlling the environment to suit the vegetables crops. Without being affected by climate change, the plant factory can produce vegetables with a certain amount, certain quality and stable price. In addition, there is no invasion of pathogenic bacteria and pests, so it can grow vegetables without pesticide.

2. Easy to manage

  • Different from the general vegetable production method depending on farmers' experience, by standardizing cultivation process, even inexperience people can perform the vegetable production work. Moreover, work in plant factory is relatively simple and easy, so the elderly and people with disabilities can be hired to preform the work in plant factory .

Demerit & Weakness

1. Best practices have not been established yet

  • There are few successful cases related to plant factory. A lot of problems still need to be fixed,

2. Low profitability

  • Initial cost of plant installation and the operation cost such as maintenance cost and management cost are very expensive, but the unit price of vegetables is low, so it is difficult to make plant factory business profitable.
