Advancements in Greenhouse Farming Equipment: Blackout and Plastic Greenhouses Revolutionize Cultivation

Nov 27, 2023

Greenhouse farming has witnessed significant advancements in recent years, with the introduction of innovative equipment and technologies. In this news article, we will explore two groundbreaking developments in greenhouse farming equipment: blackout greenhouses and plastic greenhouses. These advancements are revolutionizing the way crops are cultivated, offering improved control over environmental conditions and enhancing productivity.

What is A Blackout Greenhouse ?

Blackout greenhouses are a cutting-edge solution that allows growers to precisely control the amount of light received by plants. These structures are equipped with blackout curtains that can be automatically or manually adjusted to block out sunlight completely. This level of control is particularly beneficial for crops that require specific light conditions, such as those sensitive to photoperiod or those grown in regions with extended daylight hours.

By manipulating the blackout curtains, growers can simulate different day lengths, optimize growth cycles, and even induce flowering in certain plants. This technology enables year-round cultivation of crops that are traditionally limited to specific seasons, providing farmers with a competitive edge and expanding the range of produce available to consumers.

The Benefits of Blackout Greenhouses

Blackout greenhouses, also known as light deprivation greenhouses, offer several benefits for commercial horticulture and plant cultivation. Here are some key advantages of using blackout greenhouses:

  • Photoperiod Control: One of the primary benefits of blackout greenhouses is the ability to control the photoperiod, which is the duration of light and darkness that plants are exposed to. By completely blocking out sunlight, growers can manipulate the day and night cycles to influence plant growth and flowering. This control allows for precise timing of growth stages and can be particularly beneficial for crops that require specific day lengths to initiate flowering.
  • Season Extension: Blackout greenhouses enable growers to extend the growing season by creating an artificial environment that can be maintained independently of external weather conditions. By manipulating the light exposure, growers can continue growing crops beyond their natural growing season, resulting in increased productivity and a longer harvest period.
  • Crop Synchronization: Blackout greenhouses allow for the synchronization of crop production with specific market demands or seasonal requirements. By controlling the light exposure, growers can time the availability of certain crops to meet market needs or coincide with holidays or events. This synchronization can help optimize sales and maximize profitability.

A Plastic Greenhouse with Versatility and Efficiency

Plastic greenhouses, also known as polytunnels, have gained popularity due to their versatility and cost-effectiveness. These structures are made of durable, UV-stabilized polyethylene plastic, which provides excellent insulation and light transmission properties. Plastic greenhouses offer several advantages over traditional glass or metal structures:

  • Affordability: Plastic greenhouses are much less expensive to build and maintain than glass greenhouses. This gives smallholder farmers access to them and allows for the expansion of greenhouse agriculture in areas with limited resources.
  • Flexibility: The lightweight nature of the plastic makes the greenhouse easy to install and relocate. This flexibility is particularly beneficial for farmers who need to adapt to changing environmental conditions or crop rotation requirements.
  • Energy efficiency: Plastic greenhouses have excellent insulation properties, reducing the need for additional heating during colder months. The plastic material also scatters sunlight, ensuring an even distribution of light and minimising the risk of damage to plants due to overheating.
  • Rope protection: Plastic mulch acts as a barrier to protect crops from pests, wind and heavy rain. It also helps maintain optimal humidity levels, creating a favorable microclimate for plant growth.

Increase Productivity and Sustainability

Both blackout and plastic greenhouses contribute to increased productivity and sustainability in greenhouse farming:

  • Extended growing season: Shaded greenhouses can be grown year-round, extending the growing season and ensuring a continuous supply of fresh produce. This reduces dependence on imported goods and supports local food security.
  • Resource efficiency: The precise light control provided by blackout greenhouses minimizes energy consumption and optimizes plant growth. Plastic greenhouses, on the other hand, require less water and fertilizer due to their superior insulation and protection against external factors.
  • Crop diversity: The versatility of plastic greenhouses allows a variety of crops to be grown, including those not traditionally grown in specific areas. This promotes crop diversity, reduces monoculture practices, and increases the resilience of agricultural systems.

Types of Greenhouse Farming Equipment

Greenhouse farming equipment plays a crucial role in creating and maintaining optimal growing conditions inside a greenhouse. Here are some essential types of greenhouse farming equipment:

  • Heating system: Heating system is essential to maintain the optimal temperature in the greenhouse, especially in cold months or regions with cold climates. Common heating systems include boilers, furnaces, radiant heaters, or heat pumps. These systems help prevent frost damage and provide the necessary warmth for plant growth.
  • Irrigation systems: Irrigation systems ensure that plants receive an adequate and continuous supply of water. They can include drip irrigation systems, sprinklers, sprayers or hydroponic systems. Proper irrigation is essential for plant growth, and these systems help deliver water directly to the roots while minimizing water waste.
  • Environmental control: Environmental control systems help to monitor and regulate various environmental factors in the greenhouse, such as temperature, humidity, carbon dioxide levels and light intensity. These systems often include sensors, controllers, and automation equipment to maintain optimal growth conditions.
  • Benches and shelving: Benches and shelving systems provide elevated platforms for plants, allowing efficient use of space for easy maintenance and harvesting. They can be made from materials such as metal, plastic or wood, and can also be tailored to the specific needs of growing crops.

The introduction of blackout greenhouses and plastic greenhouses has revolutionized greenhouse farming, offering growers unprecedented control over environmental conditions and boosting productivity. Blackout greenhouses enable precise light control, allowing for year-round cultivation and expanded crop options. Plastic greenhouses provide versatility, affordability, and efficient resource utilization, making them accessible to a wide range of farmers. These advancements in greenhouse farming equipment are driving the industry towards increased sustainability, improved crop diversity, and enhanced food production capabilities.
