How to Choose multispan greenhouses?

A multispan greenhouse is a preferred choice by many agricultural producers due to its multiple interconnected sections or bays, offering a larger cultivation area. Compared to single-span greenhouses, multi-span versions significantly expand production capabilities, making them a lucrative investment for growers.

In this detailed guide, we will discuss what a multi-span greenhouse is, its distinct benefits, and critical factors to consider before constructing one.

What is a Multi-Span Greenhouse? Key Benefits

A multi-span greenhouse consists of several interconnected sections, generally constructed from steel or aluminum, featuring arched roofs and straight sidewalls. These individual bays are typically around 4 to 6 meters wide, and their lengths can be customized as needed.

One major advantage of a multi-span greenhouse is the ability to create a spacious growing environment by linking multiple bays, forming a continuous structure. This greenhouse type often includes various heating, cooling, and ventilation systems to ensure optimal growing conditions.

Additionally, multi-span greenhouses are built using high-quality materials like steel or aluminum, which are both durable and long-lasting. This makes them capable of withstanding extreme weather conditions, thus providing a secure environment for crops.

Considerations for Constructing a Multi-Span Greenhouse

For those contemplating expanding their agricultural operations or commercial growers needing more space, a multi-span greenhouse can be a wise investment. However, setting up such a structure involves meticulous planning and multiple considerations.

1. Local Climate: Assessing the local climate—including temperature, humidity, and wind conditions—is crucial for determining the types of covering materials and environmental control systems required.
2. Crop Type: Different crops have unique environmental needs. Consider the specific requirements for temperature, light, and humidity to design the most suitable greenhouse environment.
3. Structural Design: The design elements such as shape, size, and material influence the greenhouse's performance and durability. Bigger structures may require reinforced frames and foundations.
4. Budget: The costs associated with building a multi-span greenhouse can vary significantly. Assessing your budget and weighing the return on investment will guide you in making an informed decision.

Conclusion

A multi-span greenhouse can significantly enhance your crop production capabilities. By understanding its key features and considering essential factors, you can make an informed choice that aligns with your agricultural goals.

The multi-span greenhouse represents an evolution from the single arch shed, presenting enhanced utilization rates and higher levels of mechanization. With systems for automatic shading, electric rolling film ventilation, and automated irrigation, these greenhouses offer a more stable and efficient growing environment, reducing the need for manual labor. This marks significant progress in agricultural facilities, particularly in regions that have lagged in modernization.

Additional features include automated technologies such as integrated water and fertilizer machines and IoT-controlled environments, contributing to increased productivity and precise resource management. However, selecting the appropriate type of multi-span greenhouse can be challenging given the various options.

1. Film-Covered Multi-Span Greenhouse

Film-covered multi-span greenhouses, also known as arched multi-span greenhouses, are cost-effective and quickly constructed. Though the film covering might need replacement every three to five years, and their resistance to wind and snow isn't optimal for northern regions, these greenhouses serve well for seedling cultivation and vegetable production, especially in southern regions.

2. Multi-Span Greenhouse with Solar Panels

Greenhouses with solar panels for their top and side coverings offer excellent wind and snow resistance, superior thermal insulation, and high automation levels. Despite the limited ten-year lifespan of the solar panels, this greenhouse style is popular in northern regions for various agricultural activities including seedling raising and flower planting.

3. Glass-Covered Multi-Span Greenhouse

Glass greenhouses offer optimal light transmission and longevity, often lasting more than twenty years with proper maintenance. Common in high-end greenhouse designs like those seen in the Netherlands, these structures, although initially more expensive, offer long-term value through their durability and minimal light transmission decay. Suitable for both northern and southern regions, glass greenhouses support diverse activities like seedling cultivation, soilless cultures, and eco-tourism.
