Growspan Launches Highyield Venlo Greenhouses for Efficient Farming

Modern agriculture faces numerous challenges, from unpredictable weather patterns to rising operational costs. Many growers struggle with reduced crop yields, inadequate greenhouse ventilation, and shrinking profit margins. These obstacles can significantly hinder agricultural productivity and profitability.

The GrowSpan Traditional Venlo greenhouse system offers a potential solution to these challenges. Based on advanced Dutch technology, this greenhouse design aims to provide professional growers with a robust structure capable of withstanding extreme weather while optimizing growing conditions for year-round production.

The Venlo greenhouse features a high-strength aluminum roof structure combined with a hot-dip galvanized steel base frame. This construction is designed to withstand heavy wind loads and snow accumulation, offering protection for crops in various climate conditions.

• Aluminum roof structure: The lightweight yet durable aluminum components provide strength and corrosion resistance.
• Galvanized steel frame: The base structure undergoes specialized anti-corrosion treatment for long-term stability in humid environments.
• Weather-resistant design: Engineering considerations include wind and snow load calculations to ensure structural integrity.

Light availability is crucial for plant growth and photosynthesis. The Venlo greenhouse's roof system is engineered to maximize light penetration, potentially increasing crop yields and quality.

• The aluminum roof components are designed to minimize light obstruction.
• Multiple glazing options including glass, polycarbonate, and film allow growers to select appropriate light transmission levels.
• Internal design considerations promote even light distribution throughout the growing space.

Proper air circulation helps maintain stable greenhouse environments and reduces disease pressure. The Venlo design offers several ventilation options:

• Higher ventilation-to-floor area ratio compared to conventional greenhouses.
• Choice between alternating (butterfly) or continuous roof vents.
• Mechanized vent operation systems for precise environmental control.
• Options for both natural and forced ventilation approaches.

The system allows customization for different crop requirements through various covering materials and an optional climate control corridor. This semi-enclosed system at the gable end mixes interior and exterior air to regulate temperature, humidity, and CO ₂ levels.

• Creates a controlled microclimate within the growing area.
• Generates slight positive pressure to reduce insect infiltration.
• Can integrate additional equipment like dehumidifiers or evaporative cooling walls.

The Venlo system offers multiple configuration possibilities to suit different growing operations:

• Span widths ranging from 10 to 14.75 feet, with custom sizing available.
• Adjustable gutter heights between 14.5 and 21 feet.
• Flexible layout options for different crop types and cultivation methods.

The modular design approach aims to reduce per-unit area costs and shorten return on investment timelines. The climate control corridor may contribute to energy savings through optimized environmental management.

The combination of galvanized steel framing and aluminum roofing components is intended to provide corrosion resistance and extended service life, potentially reducing long-term maintenance and replacement costs.

The greenhouse system utilizes specialized software for structural and environmental simulation during the design phase. This computational approach aims to optimize greenhouse performance for specific growing conditions and crop requirements.

The Venlo greenhouse design is adaptable to various crops including vegetables, fruits, and flowers, supporting multiple cultivation methods across diverse climate zones. The system's proponents suggest it may offer solutions for growers facing challenges from variable weather conditions to energy costs.
