What Is Light Deprivation Greenhouse? The Benefits, Categories, and Pricing

A light-deprivation greenhouse uses special shading materials and an automated system to precisely control the duration and intensity of light. It is usually equipped with an advanced automation control system to create the most suitable environment for the growth of various crops. This technology allows you, as a grower, to break the seasonal limitations of traditional agriculture, achieve efficient year-round cultivation, and significantly improve crop quality and yield.

Whether used for commercial cultivation of high-end flowers and medicinal plants or scientific research, light-deprivation greenhouses show immense potential and market demand. As a professional greenhouse manufacturer,  we will elaborate on the principles and advantages of light-deprivation greenhouses in this article to better inform you about this advanced greenhouse type.

Light Deprivation Greenhouse Benefits

Light-deprivation greenhouses control light duration and intensity to increase yield and quality and extend the growing season. The flowering time of plants is controlled by both intrinsic genetic factors and environmental signals, with photoperiod being a key environmental signal affecting plant growth and development. Plants, like humans, perceive day and night changes through light and regulate their physiological activities, such as germination, leaf growth, flowering, and seed formation.

Modern agricultural technology uses light-deprivation greenhouses to regulate the growth cycle of crops. For example, the shading system of a light-deprivation greenhouse can precisely block natural light, ensuring complete darkness when plants need it. The lighting system can simulate the spectrum and intensity of sunlight, providing different light cycles according to the needs of the plants.

Whether your plants require long or short daylight, light-deprivation greenhouses can help you break the environmental limitations of crop growth imposed by the seasons, providing ideal growing conditions year-round.

Since light-deprivation greenhouses use blackout curtains, these materials offer excellent insulation, helping to maintain optimal temperature conditions within the greenhouse. Additionally, blackout curtains effectively prevent light pollution from growing lights at night. This feature is crucial for protecting the surrounding environment and ensuring the well-being of nearby residents. By blocking excessive light emissions, blackout curtains contribute to a more sustainable and community-friendly growing operation.

Light Deprivation Greenhouse Applications

Light-deprivation greenhouses are highly effective in regulating the photoperiod necessary for plant growth by controlling crop lighting. They are primarily used for the cultivation of the following crops and scenarios:

  • Medicinal Plants: Cannabis is one of the most common medicinal plants requiring a light-deprivation greenhouse. By controlling light, its growth cycle and quality can be optimized. These greenhouses can currently harvest 3-4 seasons per year.
  • Flowers: High-end flowers like tulips and chrysanthemums often use light deprivation greenhouses. Precise light control helps enhance the flowers’ ornamental value and market price.
  • Vegetables: Crops such as mushrooms are also suitable for cultivation in light-deprivation greenhouses, ensuring they grow under optimal conditions.
  • Research Laboratories: Some research labs requiring full light shielding also need light deprivation greenhouses to precisely control experimental conditions.

Light-deprivation greenhouses show broad applicability in these fields. If your area (such as high latitudes) cannot meet the photoperiod requirements of plants in some seasons, consider building a light-deprivation greenhouse. Adding a blackout curtain system is also necessary for commercial greenhouses needing to use grow lights at night to avoid light pollution. Many countries have begun legislating against greenhouse light pollution, and violating related laws could result in fines.

Types and Prices of Light Deprivation Greenhouses

The price of a greenhouse can range from a few dollars to several tens of dollars per square foot, primarily depending on factors such as the greenhouse frame, covering materials, and supporting environmental control systems. If you are preparing to invest in a light-deprivation greenhouse, here are three types you can choose from, ranging from low to high prices.

1. Low-End Light Deprivation Greenhouse

Low-end light-deprivation greenhouses typically use ordinary plastic hoop structures with an additional layer of blackout curtains covering the plastic film. These curtains can be manually or electrically rolled. This configuration is mainly suitable for small-scale growers, home growers, or gardening enthusiasts. Its main advantages are low cost, simple setup, and easy maintenance.

However, since it is not equipped with other greenhouse control systems, temperature, and humidity rely more on the natural environment. Its automation level is low, so it relies more on manual labor, suitable for small-scale cultivation with relatively low labor costs. Due to the lower controllability of crop growth conditions, the quality and yield of crops might be slightly lower than those in high-end greenhouses. If you are a small-scale grower or your crops do not have high environmental requirements, consider this type of greenhouse.

2. Mid-Range Light Deprivation Greenhouse

Mid-range light-deprivation greenhouses have significant upgrades compared to low-end ones. These upgrades include using more durable materials for the greenhouse frame and covering materials, and the blackout curtain system is located inside the greenhouse with electric control for opening and closing the curtains. Additionally, these greenhouses are equipped with necessary ventilation systems and insect nets.

Compared to low-end greenhouses, mid-range ones have a longer lifespan and can provide more precise photoperiods and other environmental factors needed for crops, thus improving growth efficiency and quality. Growers can choose additional smart system configurations according to actual needs, such as fully automated control systems, fine mist systems, and heating systems.

3. Mid-Range Light Deprivation Greenhouse

High-end light-deprivation greenhouses use the most advanced greenhouse technologies available. These greenhouses usually use the most advanced materials, such as high-strength glass or multi-layer composite materials for covering, ensuring the best insulation and light transmission performance. The blackout shading system achieves full automation and automatically adjusts light intensity and duration according to plant needs and monitored environmental conditions. With high-precision environmental monitoring systems and intelligent control systems, these greenhouses can monitor temperature, humidity, CO2 concentration, and other environmental parameters in real time, providing feedback and adjusting the parameters.

Moreover, high-end light deprivation greenhouses might be equipped with advanced irrigation systems, nutrient supply systems, and light spectrum adjustment systems to ensure the ideal growing conditions for crops. Suppose you are a large commercial grower considering entering the high-end flower market or a research institution needing precise experimental condition control. In that case, this fully automated light-deprivation greenhouse is your best choice. Although the initial investment cost is higher than the other types of greenhouse and can reach more than 20 dollars per square foot, its efficient production and high quality, in the long run, provide significant economic benefits.

Conclusion

This article explains how light-deprivation greenhouses break the seasonal limitations of traditional agriculture by controlling light duration and intensity, achieving efficient year-round cultivation. They suit various needs, from small-scale home growing to large-scale commercial cultivation. Low-end configurations are suitable for cost-sensitive small growers; mid-range configurations enhance environmental control precision through smart systems, suitable for medium-scale growers; high-end configurations are almost fully automated, suitable for large-scale commercial growers and research institutions.

As a professional greenhouse manufacturer, INSONGREEN can provide various configurations of light-deprivation greenhouses to meet the different needs of customers, helping you improve the quality and yield of your crops.
