Kupolimaisiin

Kupolimaisiin is a type of Finnish hothouse consisting of a geodesic dome, typically made of steel or wood, designed to create a warm and controlled environment for crops. The structure is usually large, ranging from 10 to hundreds of square meters, and is often used for growing exotic plants, such as orchids and tropical fruits.

The concept of kupolimaisiin was first introduced in Finland in the 1960s by agricultural engineer Pekka Kairamo, who designed a geodesic dome to study and demonstrate innovative plant growth methods. The dome's shape provides optimal insulation and allows for efficient use of space, while the use of glass or plastic sheeting on the exterior allows for maximum natural light penetration.

A kupolimaisiin typically consists of a geodesic structure, supported by a framework of diagonals and triangular elements, creating the characteristic dome shape. The interior is usually covered with a clear plastic sheet, which allows for photosynthesis to take place, while the exterior is coated with a reflective surface to minimize heat loss. The walls and floor of the dome are often covered in insulation to maintain the internal temperature and humidity levels required for optimal plant growth.

Kupolimaisiin structures have been widely adopted in Finland and other countries with cold climates, where they allow for the year-round cultivation of a wide range of plants, independent of the local growing season. These structures have also been used in research and educational settings to study plant physiology and to promote sustainable agriculture practices.
