Greenhouses for orchids


Orchids are very loved and highly appreciated plants not only for their particular beauty but also for the fact that they are very well suited for use for decorative purposes. They are plants that require a lot of care, attention and small precautions to ensure that they develop in the best way. They are by no means easy to grow plants, in fact, care must be taken in making them receive the right amount of light, water and humidity, in choosing the soil to use and in pruning and fertilizing. Obviously, if we don’t respect the right care they need, the blooms won’t be as abundant and shiny enough as we want. The orchid genus includes various species and, like any plant, each species has particular characteristics that differentiate it from the others and needs that must be respected. To get to know orchids better or, better said, to understand the right environment to cultivate them and make them grow healthy, just think of their place of origin. They are native to tropical areas and therefore to places where temperatures are high and there is a lot of humidity. The only seasons orchids are used to are dry and rainy.

What to know

Returning to the discussion made previously, in their places of origin, orchids follow a certain standard of life. The same life cycle is also followed in our areas and with our climate. Orchids have a dormant period that ends with the growth of new shoots and, during this period, the plants must be dry and must not be fertilized. Once the roots are born, the orchids must be watered and fertilized with fertilizers that contain nitrogen. A very important thing for these plants is to create a microclimate that suits their needs. To create an adequate climate, water must be sprayed on the leaves of the plant, avoiding wetting the flowers. This operation should preferably be carried out in the morning so that the plant dries up to face the night. In addition to temperatures, the amount of humidity around the plant is also important. To create humidity, just place the pot on a saucer with expanded clay or gravel inside. This will ensure a humid environment without the root system coming into contact with water and thus avoiding root rot or fungal diseases.


By virtue of what is written in the previous paragraphs, greenhouses are an important investment for our orchid plants. There is not always a need to create a real greenhouse but it is enough to create a situation that reflects their natural habitat. If, on the other hand, you want to build a real greenhouse, you must be aware of the fact that some things must be managed with specific technological systems that often turn out to be quite expensive. An important aspect is the choice of the energy source to use, whether it is diesel oil or thermal springs. The choice must be made based on the type of cultivation that is carried out, as we have already said, each species has particular preferences. For the growth of these types of plants, the temperature is a very important factor and in fact, the greenhouses, they must be heated in winter and cooled in summer. As for heating, it is enough to use simple systems or use stoves while, for cooling, the walls could be opened in such a way as to circulate air and let in external air that will certainly be cooler than the internal one. Remember, however, that heating with air involves a drier environment which on the one hand could be seen as a limitation but, on the other, could be a positive factor.

Greenhouses for orchids: Moisture and vacuum

Humidity, like temperature, is important for orchid plants. Creating moisture for a potted plant is not a difficult job at all, just place a saucer under the pot and fill it with expanded clay, pebbles or gravel. In greenhouses, however, the work is different and requires a little more patience and attention. Humidity can be created using a vaporizer or by nebulizing the leaves of the seedlings with special compressors. Goli humidifying tools can be purchased in any shop that deals with gardening. Despite all these attentions and precautions, temperatures during the day must be checked. To carry out these checks, simply place a vacuum cleaner in the highest area of ​​the wall which allows, on one side, the exit of the air accumulated inside and, on the other hand, the entry of fresh air from the outside. In this way, however, there is a risk of completely cooling the internal environment. To avoid this, the air that enters the greenhouse from the outside should be humidified. The aspirator must be positioned according to the climate that you decide to have inside the greenhouse. If we place it in the north it creates a homogeneous temperature in the greenhouse, if instead we place it in the south, different climatic sectors are created in the same environment.
