Greenhouses are structures of different sizes and shapes, designed to provide ideal humidity and temperature conditions for growing flowers, fruits, vegetables, and other crops.
Demand for greenhouses is growing more and more, both in the professional market and in the market of home greenhouses. Whether you are a professional or an amateur, the greenhouse is always a bargain.
They are made of various materials such as PVC or polycarbonate for exterior coating and supporting structure of aluminium or metal treated against corrosion. They have windows or certain vents, and some more expensive models even have a base for the floor.
In general, it is difficult to protect crops from bad weather. That’s why gardening enthusiasts are looking for an option to keep them.
If you are thinking of buying a greenhouse but do not know which and how to choose, here is a little more information to help you in this task.
The market offers a wide variety of different types of greenhouses:
- PVC greenhouses: their quality varies depending on the plastic used for their production. PVC greenhouses are cheap, easy to install, retain heat well and help a lot with their insulating properties. However, you should also know that they are less resilient than others. Polyethene is more durable than PVC but is more expensive. They transmit light better than those of PVC and also have insulating properties.
- Mini greenhouses: they are usually very small and are designed to be kept indoors with houseplants. They are usually easily portable so that they can be transported from outside to inside and back.
- Glass greenhouses: they are the ones that transmit light best. They are beautiful and aesthetic, but they need very durable constructions to keep them stable, as the glass panels are very heavy. We must say that they do not insulate too much because the glass is cooled or heated depending on the outside temperature and does not keep it very constant.
- With wooden structure: The structure is made of a wooden frame that holds the coating. They are beautiful and inexpensive, but the tree requires special care to protect it from the weather and moths.
- Polycarbonate greenhousesare durable and of better quality than PVC and polyethene, but they are more expensive. They are resistant to UV rays and are incredibly durable.
Can you make money with the greenhouse?
You can earn with the greenhouse, depending on how you use it. When it comes to use, you need to consider not only the crops you have been able to sell (if you are committed to it) but also the personal satisfaction that caring for your plants can bring you.
Remember that many people do not grow seedlings or vegetables for sale. There are gardening enthusiasts who are truly committed to their plants and do so without any motive for profit.
Significant cash investment is not always needed. Suppose it is a very large greenhouse or expensive materials such as glass. In that case, the profitability of the greenhouse will depend on the good results or the product grown and the benefit it brings you.
Always keep in mind that the profitability of the greenhouse is calculated in the long run, not just for the first year.
When buying a garden greenhouse, you need to consider factors such as the size you will choose and the space you have.
Another factor is the material, which determines whether its durability will be greater or less.
The safety of your construction is also important, depending on whether it is designed to withstand torrential rain and wind or milder weather conditions. In the same way, maintenance is also essential. Do not forget the wooden structures that require special treatments.
With all this information, you certainly already know what you need and you are already thinking about what plants to grow. But if you have not yet decided, do not think much, growing houseplants, fruits and vegetables is always very useful.
Useful tips for growing plants in a greenhouse
The best thing about growing plants in a greenhouse is that it allows us to work on cold days at a temperature that is at least 5 degrees higher than the temperature outside. This helps us prepare the beds earlier.
- Location: To make the most of the light, it is good to place it along its length from east to west, if possible, of course, and if nothing obscures it. If you do not have enough sunlight, you can use artificial lighting with high-pressure sodium lamps, and in case you have too much sun, you can use protective screens to shade your crop.
- Regular cleaning: The accumulation of dust and dirt reduces the amount of light that enters the greenhouse. That’s why it’s important to keep it clean from the outside.
- Control ventilation: It is recommended to open windows and doors for at least 1 hour a day so that you can renew the air in the room and control excess humidity. Remember to ventilate when it is not very cold so as not to lose the necessary heat. If it’s summer, you can even leave the windows and doors open at night. In case you can afford it, you can install automated ventilation. Ventilation also allows pollinating insects to reach the flowers, as this is essential for many fruits.
- Maintain constant humidity: It is good to maintain consistent moisture in the soil of the plants. Adjust the irrigation according to the temperature, do not water too much, as what you will achieve is the suffocation of the roots (asphyxia), and if you do not water enough on hot days, the plants will dry out. The ideal way to control humidity and avoid possible pests is to buy a hygrometer. This way, you will know the humidity at any time.
- Take care of the plants: Clean the pots well to prevent pests and diseases. Remove dry or diseased leaves. Water them at a temperature between 18 and 25 degrees. When the day is cold and cloudy, reduce watering. Use fertilizers that contain trace elements.
