Winter often delays gardening plans and prevents an early spring start to the harvest of fresh plants. Despite the complicated climatic conditions, however, there is a proven way to cope with this limiting period – the use of greenhouses and low greenhouses on the principle of their own heat source. These simple, yet effective structures can dramatically speed up the growing season and protect young plants from frost without the cost of expensive heating. In conjunction with products from renowned brands such as LANIT PLAST, GALECO or VITAVIA, the way is opened to effective and sustainable gardening that will push the boundaries of the season even where the winter is the harshest.
Greenhouses represent a traditional but still very effective way of using the heat generated by the decomposition of organic material, such as fresh horse or sheep manure. This thermal process can increase the thermal comfort of seedlings by several degrees above the ambient outdoor temperature, which will allow for earlier sowing and harvesting. Compared to modern heated greenhouses, which can be financially demanding and dependent on energy supplies, a greenhouse brings independence and ecological savings.
Making a greenhouse is also accessible to less skilled gardeners – all you need is a few planks, old windows or the use of transparent materials such as polycarbonate from POLYTOP, wood-plastic materials from ALUMONT or plexiglass. The structure can be supplemented with opening hinges drawn from the reuse of window frames, which allow for temperature regulation inside during the day and night.
When building a greenhouse or small greenhouse, it is crucial to choose the right materials that will provide the best possible thermal insulation properties and at the same time withstand the weather. Polycarbonate sheets from renowned manufacturers such as VITAVIA are an ideal choice due to their durability and insulation capabilities. The combination with wood-plastic from ALUMONT or HOBBYTEC will give the structure stability and aesthetics. If old windows are available, it is recommended to preserve them and use their double glazing to increase thermal insulation.
The correct location of the greenhouse is also essential – on the sunny south side of the garden with minimal shade to maximize natural heating. It is also important to maintain regular maintenance, including regular ventilation to prevent mold, and proper irrigation with room temperature water so that the plants do not suffer thermal shock when watering.
Greenhouses are an ideal place for pre-growing cold-loving plants and fast-growing vegetables, such as salads, radishes or spring onions. They help the gradual acclimatization of seedlings, which is key to their survival and a rich harvest after transplanting into open ground.
In the 2025 season, interest in a sustainable and self-sufficient way of gardening is still growing, where brands such as JANO, GUTTA or URBIS offer high-quality accessories and equipment for the proper care of greenhouses and small greenhouses. These products ensure not only plant protection, but also the convenience of gardeners during handling and maintenance. For example, effective roller shutters and temperature sensors significantly increase the possibilities of climate control in the greenhouse.
The traditional method of using heat from organic material is supplemented by modern methods, such as mulching the sides of the greenhouse with leaves or mulch bark, which minimizes heat loss from the sides of the structure. Regular ventilation during warmer days prevents mold and overheating, even without the need for electric fans.
For gardeners without access to fresh manure, there are alternatives such as using straw, potato tops, or brewery threshing floors at the bottom of the greenhouse, which also generate heat when decomposed. At the same time, it is advisable to follow the rules of building law, for example on the pages how many m2 can I build without a permit and what construction do I have to report, so that the construction is legal and in order.
Mini greenhouses and greenhouses are among the most sustainable options for extending the gardening season without significant energy costs. They enable biological insulation through the natural decomposition of natural material, which is not only economical but also environmentally friendly.
Additional benefits are provided by products from the POLYTOP or VENDYS brands, which specialize in modular accessories, shading or irrigation systems adapted to these types of structures. These technologies help to adjust the microclimate and simplify care even for novice gardeners.
The basic rule that should apply to every greenhouse owner can also be found in the article on Choose a greenhouse, greenhouse or foil house, which summarizes the importance of choosing the right structure according to the needs of a specific garden and planned crops.
