vihreätalueet

Vihreätalot, or greenhouses, are structures used for growing plants. They are typically made of transparent materials like glass or plastic, which allow sunlight to enter while trapping heat. This creates a controlled environment that is warmer and more humid than the outside, ideal for cultivating a wide range of plants, especially those that may not thrive in the local climate.

The primary purpose of a vihreätalo is to extend the growing season, allowing for earlier planting in spring and later harvesting in autumn, or even year-round cultivation. This is particularly beneficial in regions with harsh winters or short growing periods. They also offer protection from adverse weather conditions such as frost, heavy rain, and strong winds.

Vihreätalot come in various sizes and designs, from small backyard hobby greenhouses to large commercial operations. The transparent covering, known as glazing, can be single or double-layered to improve insulation. Ventilation is crucial to prevent overheating and disease, and this is often achieved through roof vents, side vents, or electric fans. Heating systems can also be installed to maintain optimal temperatures during colder months.

The controlled environment within a vihreätalo allows for precise management of factors like temperature, humidity, light, and water. This can lead to increased crop yields and improved quality. They are used for growing a diverse array of plants, including vegetables, fruits, flowers, and ornamental plants.
