Richel - Semi-closed Greenhouse

In a context where sustainability and the quality of agricultural products have become top priorities, Richel’s semi-closed greenhouses offer an innovative solution. They enable producers to combine agronomic performance, environmental responsibility, and food safety. These greenhouses provide an optimal growing environment while reducing the impact of chemical inputs and preserving natural resources. Thanks to advanced climate management technologies and integrated biological pest control solutions, they set a new benchmark for more sustainable and profitable agriculture.

Richel’s semi-closed greenhouses are specifically designed to limit the infiltration of insects through a positive pressure system. Combined with integrated biological control, this system enables pesticide residue-free production, which is healthier for consumers. It also generates savings on the use of plant protection products for producers.

Farmers can adopt more natural pest control methods, such as using natural predators or biopesticides. The reduction of chemical inputs leads to healthier products that meet the expectations of consumers seeking quality and food safety.

The greenhouses are equipped with insect-proof nets placed over the air intakes on the gables or long spans. This centralized placement makes their monitoring and maintenance easier. A dynamic active ventilation system, coupled with heating and cooling systems, ensures optimal climate conditions from the roots upward. This ventilation dries the plants and limits the development of fungi and molds, such as mildew. Finally, a precise system for controlling humidity and temperature helps strengthen plant health and their resistance to diseases.

Richel’s semi-closed greenhouses provide better climate uniformity across the entire growing surface, promoting optimal plant growth throughout the year. Our systems allow precise climate control, with cooling, heating, and dehumidification functions. Thanks to a reduced number of vents, shading zones are minimized compared to traditional greenhouses, providing more light for plants. Temperature distribution is also optimized, keeping the roots cool and the tops of the plants warm. Additionally, they increase CO2 levels within the greenhouse, stimulating photosynthesis and plant growth.
