Greenhouse horticulture

Greenhouse cultivation represents one of the most effective solutions for vegetable and flower farming, especially when the external climate is too harsh or unpredictable. However, even inside the greenhouse, managing climatic conditions is essential to ensure healthy and productive plant growth. Idromeccanica Lucchini supports farmers with cutting-edge solutions and personalized consultations to tackle every climatic challenge and optimize yields. In this article, we offer you 5 practical tips for a well-managed greenhouse, taking into account different climatic conditions.

1) Temperature management: protect the plant from thermal stress

One of the most critical aspects of greenhouse cultivation is controlling the internal temperature. Temperature fluctuations between day and night, especially during seasonal transitions (winter spring and summer autumn), can have devastating effects on plants. In particular, crops like tomatoes, eggplants, and berries are particularly sensitive to such thermal excursions. These fluctuations stress the plants, slow growth, and promote the development of diseases.

In a greenhouse, thermal control can be achieved through two main approaches: active and passive. Active climate control, which includes heating, cooling, and ventilation systems, allows for dynamic temperature regulation, while the passive approach focuses on thermal insulation, using specific materials as in our Defendo System, to keep internal conditions stable. Additionally, it is crucial to implement buffer zones (greenhouses within the greenhouse) to avoid extreme thermal excursions and to monitor the temperature remotely with the help of advanced sensors.

2) Light control: protection from excessive solar radiation

Plants not only need light for photosynthesis, but they are also sensitive to the intensity and duration of solar radiation. Too much light can damage crops, especially during the central hours of the day, causing thermal stress and reducing photosynthetic efficiency. Let’s take an extreme global example: in contexts like the United Arab Emirates, where the sun is intense but light can be insufficient in some seasons, or in Finland, where plants can receive too much light even if temperatures are mild.

The solution lies in an automatic shading system that adjusts light intensity based on the sun’s position and the plants’ needs. Lucchini offers various internal and external shading options, with automated systems that respond to changes in light intensity, protecting crops from the risk of sunburn or thermal stress. The use of light sensors, placed both inside and outside the greenhouse, allows for optimized shading, minimizing energy consumption and improving plant performance.

3) Ventilation: ensure air exchange to prevent diseases

Good ventilation is essential to maintain a healthy greenhouse environment conducive to plant growth. The accumulation of humidity inside, combined with insufficient air exchange, can promote the proliferation of pathogens and the formation of harmful gases, reducing photosynthesis and slowing growth. To avoid these risks, it is essential to maintain a stable relative humidity around 70%, while ensuring continuous air exchange.

Idromeccanica Lucchini offers a variety of solutions for active and passive ventilation: air extractors, fans, manual or motorized windows, and panel cooling systems are just some of the options that ensure efficient air exchange. The use of integrated humidity and temperature sensors in ventilation systems also allows for real-time monitoring and regulation of the greenhouse’s internal conditions, avoiding problems related to excess humidity and improving photosynthesis efficiency.

4) Irrigation management: balance between water and nutrients

Irrigation is one of the most delicate aspects of greenhouse management. During hot periods, plants require more water, but water resources are often limited, and water quality can be compromised by the presence of salts and other impurities. Additionally, irrigation must be distributed evenly to avoid water stress on the plants, which can damage roots and reduce growth.

Lucchini offers advanced solutions for automated irrigation, including fertigation systems (mixing water and fertilizers) capable of optimizing nutrient absorption by plants. Monitoring soil moisture sensors allows for irrigation regulation based on the specific needs of each plant, reducing waste and optimizing water resource use. In scenarios of water scarcity (unfortunately increasingly frequent in the near future), we also suggest rainwater harvesting systems and the creation of storage basins to ensure continuous irrigation even during crises.

5) Consulting and design: optimize the greenhouse with targeted professional expertise

Every greenhouse is a unique world, and designing an ideal environment for crops requires an engineering approach that considers every single aspect. This includes not only the physical environment where the greenhouse is located but also the characteristics of the plants, issues related to sustainability and environmental regulations. For this reason, Idromeccanica Lucchini offers specialized consultations to help farmers design customized greenhouses and optimize every cultivation cycle.

Regular maintenance of the greenhouse, like that of a living organism, is essential to ensure a long useful life for the structure and reduce management costs. Preventive maintenance of systems, combined with continuous monitoring systems, allows for timely detection and resolution of any malfunctions and/or emergencies, improving operational efficiency. Lucchini also offers data tracking software that allows for real-time monitoring of internal and external climatic conditions of the greenhouse, providing precise guidance for managing and scheduling agricultural activities.
