Hydroponic Cultivation Solution

The biggest advantage of hydroponics in indoor agriculture is that the cultivation area per building area can be increased by increasing the number of cultivation stages to 5 to 6 tiers. can be said On the other hand, management costs such as heating and cooling are higher in vertical multi-layered cultivation than in open-field cultivation.
very advantageous However, in multi-layered cultivation, the height of the building increases is a matter to be aware of. In 6-tiered cultivation, the height of the building is about 5m. Considering the convenience of work, a separate facility should be installed.

In this case, it may be the most convenient and safe method as it has a two-story structure by installing a steel scaffolding for work in the passage at 2.5m in the middle, but it has the disadvantage of being expensive. On the other hand, there are methods such as installing a vertical moving work platform in the form of rails on the structure for cultivation and installing facilities so that the three or more stages can work using these movable work platforms, or a method of purchasing and using a movable safety ladder. You will need to select equipment suitable for the size of the farm in consideration of such factors.

If the height is high like this, there is a problem in terms of temperature management, especially the upper and lower temperature deviations that occur during heating in winter. That is, the heating temperature up to the lower 3 stages is optimal at about 20°C, but the top 6 stages are 25°C.
Heating and air agitation facilities must be added to solve the temperature difference.

The ventilation system is also a part that cannot be overcome. Plants use light from the leaves to use water and CO2 in the air as raw materials to photosynthesize, making glucose and oxygen, and storing the glucose in the leaves in the form of starch, and releasing oxygen into the air through the stomata.

Recently, the concentration of CO2 in the air in the natural state is 420ppm, which is 20ppm higher than a decade ago, and is a major cause of global warming.
Mushrooms are ventilated when the carbon dioxide concentration is excessive, whereas plants need ventilation when the carbon dioxide concentration is insufficient. Ventilation by the interpolar air volume through the poles will suffice, but a small-scale ventilation system is also required because a certain amount of ventilation is also required.

Humidity management is also important, and although there are many facilities inside the cultivation company, such as the culture soil sprinkling device storage tank, that can increase the humidity in the air by evaporating due to exposure to the atmosphere. Humidification equipment is required for humidity control when this is active and after planting of ginseng seedlings. However, in the case of a greenhouse with no cooling facilities or a low number of cultivation stages, the humidifier can be omitted.

Lighting Equipment Light is an unconditionally necessary facility for photosynthesis, and it is a facility that replaces sunlight. It is the most important facility that determines the amount of electricity consumption, that is, the power supply capacity among hydroponic facilities.

Because ginseng does not require much sunlight due to its growth characteristics and its growth is very slow compared to other plants, it is necessary to supply only the appropriate amount of light necessary for optimal growth conditions.
Excessive light quantity increases cost due to over-design. Accurate light quantity design is the most important part because you have to pay expenses that you do not need to pay, such as basic rate, safety management fee, etc. The amount of light should be accurately designed.
Here, the wavelength related to photosynthesis is a blue-red wavelength, and the optimal amount of light is 50 μmol.
