How to manage a blackout greenhouse more effectively?

Jun 11, 2024

Blackout greenhouse is a type of greenhouse that allows growers to control the amount of light that plants receive. This is achieved by using shading materials or systems that can be covered over the plants to completely block out the light.

Compared to ordinary greenhouses, blackout greenhouse are highly efficient. They are suitable for growing crops that have special light requirements or are in special growth stages.

Here are the features and advantages of shade greenhouses.

1. Control photoperiod. Some plants’s growth or flowering phase is triggered by changes in the light-dark cycle. Blackout greenhouses allow growers to manipulate these cycles to induce flowering at any time of the year.

2. Multiple harvests. By controlling the light cycle, growers can harvest multiple times in a year. This can significantly increase yields and profitability.

3. Energy efficiency. Shading materials also provide insulation, helping to keep the temperature inside the greenhouse constant. This can reduce energy costs associated with heating or cooling.

4. Prevent light pollution. In urban areas, light pollution can disrupt the growth cycle of plants. A shade greenhouse protects plants from external light, ensuring that growers have full control over light exposure.

5. Versatility. During periods when shading is not required, the shade system can be retracted and the greenhouse can be operated like a regular greenhouse.

However, the shade greenhouses require careful management to prevent problems such as mold or pests caused by high humidity and high temperatures brought by darkness. Proper ventilation and climate control systems are essential to maintaining a healthy growing environment.

How to manage a shade greenhouse more effectively?

Here are some key methods and equipment for precisely controlling environmental factors.

1. Light control.

Shading system. By installing external shading and internal shading nets, the degree of shading can be adjusted according to the season and crop needs, effectively blocking excessive sunlight and preventing crops from being burned while maintaining appropriate light intensity.

Artificial lighting system. In the case of insufficient light, artificial light sources such as high-pressure sodium lamps are used to supplement light to ensure that crops obtain sufficient energy for photosynthesis.

Intelligent lighting control system. Combine sensors and automatic control systems to monitor the light intensity in the greenhouse in real time, and automatically adjust shading equipment and artificial light sources according to crop needs and light changes to achieve precise light control.

2. Temperature regulation.

Greenhouse insulation materials. Use high-efficiency insulation materials to reduce heat loss and improve the insulation performance of the greenhouse at night.

Ventilation system. By opening the side windows or top windows of the greenhouse, using natural ventilation or mechanical ventilation, adjust the temperature in the greenhouse to maintain a suitable growth environment.

Cooling system. Using the principles of water evaporation and condensation, the temperature in the greenhouse is reduced through specific heat dissipation equipment, especially during the high temperature period in summer.

Heating system. In cold seasons, heating equipment such as hot air furnaces and floor heating are used to increase the temperature in the greenhouse to ensure normal growth of crops.

3. Humidity management.

Humidity sensor and control system. Use humidity sensors to monitor the humidity level in the greenhouse in real time, and combine with automatic control systems to adjust green house small environment, irrigation and other equipment according to crop needs and humidity changes to maintain a suitable humidity environment.

Intelligent irrigation system. Use precision irrigation methods such as drip irrigation and sprinkler irrigation to automatically adjust the irrigation amount according to the water demand of crops and soil moisture to avoid adverse effects of excessive or low humidity on crops.

4. Other environmental factors.

Soil environment monitoring. Use soil sensors to monitor soil moisture, temperature, pH value and other parameters to provide a suitable soil environment for crops.

5.Carbon dioxide concentration control. 

By increasing the carbon dioxide concentration, the photosynthesis of crops promoted, and the yield and quality improved. This can become a special carbon dioxide generator or ventilation system.

In summary, the shading greenhouse uses a comprehensive application of shading systems, artificial lighting systems, ventilation systems, heat dissipation systems, heating systems, humidity control systems and soil environment monitoring. Combined with the application of intelligent management systems, the accuracy and efficiency of environmental control can be further improved.
