What are the main limitations of traditional commercial greenhouses?

The main limitations are the continued influence of outdoor temperature, light, humidity and seasonal changes on the greenhouse climate. Integrated climate control gives growers more possibilities to actively manage these conditions.

Is year-round growing possible in every greenhouse?

That depends on the crop, location, greenhouse design and available technical systems. The greater the difference between the desired growing climate and the local outdoor climate, the more climate control is required.

How does climate control affect greenhouse energy consumption?

Climate control can require energy for processes such as heating, cooling and ventilation. By managing technical systems together and reducing unnecessary energy losses, available energy can be used more efficiently.

Greater control over climate and year-round production

A greenhouse designed for year-round growing starts with the right balance between crop, climate, energy and technology. Want to find out which greenhouse solution best fits your crop, location and production objectives? Discuss your project with KUBO.

How can greenhouse design support year-round growing?

An integrated greenhouse design combines the structure, climate systems, screening, water management, cultivation systems and software around the needs of the crop and the local climate. This helps growers create more stable growing conditions and use energy and water more efficiently.

What is the difference between a semi-closed greenhouse and a traditional greenhouse?

A traditional greenhouse controls the climate largely through natural ventilation via roof vents. A semi-closed greenhouse also uses mechanical ventilation, positive pressure and air treatment. As a result, the greenhouse climate is less dependent on outdoor conditions and can be kept more stable.

How does a semi-closed greenhouse contribute to energy efficiency?

Because less heat and supplied CO₂ are lost through open vents, energy and CO₂ can be used more efficiently. Technologies such as air mixing and heat recovery can further optimize energy use. The actual savings depend on factors including the climate, greenhouse design, crop and energy supply.

Does a semi-closed greenhouse result in higher crop yields?

A semi-closed greenhouse can create conditions that support stable and predictable production. A more consistent climate and more precise climate control can contribute to crop growth, quality and production reliability. The final yield remains dependent on factors including the crop, cultivation strategy, location and operational management.

When is a semi-closed greenhouse an attractive option for a large-scale horticultural project?

A semi-closed greenhouse is particularly attractive when climate control, energy efficiency, water use and production reliability are important factors in the business case. For large-scale growers and investors, the local climate conditions, available energy sources, crop and desired production output should therefore be assessed together. KUBO tailors Ultra-Clima® to these specific conditions.

What is the main limiting factor for crop growth in winter?

Light is the primary limiting factor during the winter months. In the Netherlands, greenhouses receive only 10–15% of summer light levels in December. This directly limits photosynthetic capacity. KUBO’s Ultra-Clima® optimizes the use of available light by creating stable climate conditions that minimize crop stress.

How much energy can be saved with modern greenhouse systems?

Semi-closed greenhouse systems can save up to 18.5% in energy compared with traditional Venlo greenhouses. KUBO’s Ultra-Clima® achieves this through heat recovery, efficient cooling and smart ventilation systems that recycle heat instead of releasing it outdoors.

Can I grow year-round without fossil fuels?

Yes, this is possible with the right infrastructure and strategy. KUBO’s CO₂-negative cultivation strategy combines residual heat, efficient climate control and smart CO₂ utilization. This results in a cultivation system that captures more carbon than it emits while maintaining high yields.

How can I prevent pests in my greenhouse without chemicals?

Semi-closed greenhouse systems use positive air pressure to keep insects out. KUBO’s Ultra-Clima® creates a physical barrier against pests. Combined with biological pest control and good hygiene practices, this makes pesticide-free cultivation achievable for many crops.

What does switching to high-tech greenhouse horticulture cost?

The initial investment in an Ultra-Clima® greenhouse is higher than in a traditional Venlo greenhouse. However, lower operating costs, higher yields and reduced energy consumption result in an attractive long-term return on investment. KUBO provides tailored advice to help you find the best balance for your specific situation.
