Advanced greenhouse complex for growing vegetable plants in Poland Kisiele, Poland About Krason has been Poland’s leading specialist in growing vegetable plants for both greenhouse and outdoor cultivation for more than twenty years. With an international customer base, its own innovations and developments, and high quality, it is not surprising that Krason now has a well-stocked trophy cabinet. Besides the design and supply of the greenhouse, Certhon was also responsible for the accompanying heating installation, including hoist heating, boiler house, and heat storage tank. Fully integrated with the CHP installation. The ultramodern greenhouse complex originally spanned 5.3 hectares, consisting of five sections and a 1.1-hectare workspace. We have now expanded Krason to 8.6 hectares. From the development of the first phase, the necessary preparations were made for essential systems such as spray booms, hoist heating, a double horizontal screen, vertical fans, and lighting. The entire facility is fully equipped to meet the demands of a modern plant nursery. The latest technologies have been implemented to ensure optimal plant handling. Additionally, the entire complex has been designed with future expansion in mind.

We think along and we think further. In this project, too, that results in special highlights: Hybrid energy solution This project stands out due to the integration of a hybrid energy solution, combining sustainable energy sources with smart energy management systems. This significantly reduces the greenhouse’s ecological footprint and enables efficient production with minimal environmental impact. Modern hoist heating The cultivation of a vegetable plant begins with a seed and only ends when the plant is strong enough to be delivered to the customer. To ensure a constant, optimal air temperature throughout the growth process, we have designed and installed an advanced hoist heating system. This system moves along with the growing plants, allowing them to thrive under ideal conditions. Maximum cultivation results with LED and HPS The greenhouse is equipped with a hybrid lighting system, consisting of 50% high-pressure sodium (HPS) lamps and 50% LED lamps. This system is designed to provide high light intensity, ensuring optimal conditions for seedling growth throughout the year, especially during the dark winter months when natural light is limited. Storm resistant The greenhouse project is designed with exceptional storm resistance, capable of withstanding extreme weather conditions. Thanks to innovative construction techniques and high-quality materials, the greenhouse meets the strictest safety standards. Its robust structure provides reliable protection for crops and installations, ensuring business continuity and customer confidence in all climates. Ebb and flood floor All sections are equipped with a modern ebb and flow system for efficient irrigation. Water temporarily flows over the floor and is then drained, promoting uniform water absorption and minimizing waste. This results in improved plant health. Automatic potting machine The greenhouse consists of two sections, separated by a large sliding door across the central pathway. An automatic potting machine moves along this main pathway, efficiently spacing plants from head to head. Interested? Also a great result for your company?
