Buy a greenhouse directly from Hoklartherm

Freestanding greenhouses in various sizes and designs are the classic option. When thinking of the term “greenhouse”, people usually imagine a freestanding glasshouse.

In contrast to freestanding glasshouses, lean to greenhouses can be the ideal solution for small spaces. Acting as a space miracle, it is directly attached to the house wall. It also serves as an energy buffer and allows for good crop yields. Other types of greenhouses include tomato greenhouses as well as greenhouses for balconies or terraces. The suitable greenhouse always depends on the desired use and the location for installation.

When deciding to purchase a greenhouse, it is important to consider the material. High-quality greenhouses are usually made of strong, powder-coated aluminum profiles with a high roof load capacity. Their metal surface is corrosion-free, unlike steel, and can withstand any weather conditions in the long run, requiring minimal maintenance.

The coating of the aluminum profiles can be done in any color, with the most common greenhouse color being fir green. However, nowadays, there is an increasing demand for glass greenhouses in anthracite or black. Of course, we can also coat the profiles in a custom color according to RAL specifications. How about a greenhouse in pure white, for example?

The choice of glazing can greatly affect the functionality and appearance. You have the options of choosing between twin-wall polycarbonate panels, safety glass, or ISO safety glass, which is typically 16-22 mm thick. If you want to overwinter plants, it is important to pay attention to the glass thickness and thermal qualities. Instead of using glass clips, we use aluminum glazing bars, which permanently hold the glazing in place. Unlike plastic glazing bars, these do not rot or become porous, ensuring optimal insulation properties and a secure hold. Additionally, the replacement of glass panels is easily possible with our products.

In addition to profiles and glazing, there are other options available for a beautiful appearance. High-quality decorative elements on the roof ridge enhance a nostalgic impression and create a certain cottage garden look. The English style can also be reinforced by installing the greenhouse on a brick foundation. Even with a brick foundation, the greenhouse door is always set at ground level. Therefore, the execution with a foundation must be specified at the time of ordering. Another quality feature is the design of the windows and doors. In our case, they are always made with ISO safety glass. The greenhouse door is also manufactured as a split swing door, allowing it to be fully or partially opened.

There are different types of glass to choose from for the glazing of the greenhouse. Depending on optical, functional, and financial preferences, both real glass and plastic can be used. Real glass not only meets the highest aesthetic demands but also proves to be extremely stable and durable. For safety reasons, we always use safety glass in the roof area of the greenhouse. One advantage of real glass in the roof area is heat gain from sunlight. Due to its high light transmittance, glass greenhouses should generally be combined with a shading roller blind. In contrast to hollow chamber plates, a glass greenhouse with clear glass retains its attractive appearance for a long time. In addition, there are no hollow spaces for moisture or algae formation in the glazing. On the other hand, glazing the greenhouse with hollow chamber plates represents a cheaper option. These plastic plates are stable and UV-resistant and are made of polycarbonate. They are also known as twin-wall sheets. Another advantage of these twin-wall sheets is their low weight. Which glazing should one choose now? How about a compromise between aesthetics, durability, and price? A combination of glass in the wall area and hollow chamber plates in the roof area can be a clever solution.

The prices of the individual Hoklartherm greenhouses depend on the floor space, type of glazing, and equipment. Therefore, it is best to go and see your new greenhouse for yourself. We also recommend getting intensive advice. This way, you can convince yourself of the quality. To compare models and their prices in the online shop, you should pay attention to factors such as glass thickness, thickness of aluminum profiles, and roof load capacity. The low weight of the basic structure also provides insights into its stability.

When you have found a suitable greenhouse, the location plays an important role. A sunny spot is recommended. The greenhouse should be protected from the midday sun on the south side by trees and shrubs. The entrance should not face the weather side. It is optimal to set up long greenhouses in a north-south orientation. This allows a lot of light to enter on the broadside in an east-west orientation.

It is also advisable for the greenhouse to have easy access on the sides. This simplifies the setup and future maintenance. You should also consider the required minimum distance to the neighboring boundary. It is definitely recommended to obtain the neighbors' consent in advance. If the minimum distance to the neighboring property is not maintained, it is called a border construction. This is only permitted in certain cases. In any case, it is necessary to check in advance if a building permit is required for the greenhouse. You can find details about the building permit in our guide on the topic.

Do you only want to accommodate a small amount of vegetables and summer flowers in your greenhouse? For that, there is enough space in a small greenhouse of 3 to 8 square meters.

However, those who want to provide for a family of four will need 10 to 12 square meters. This provides enough space for two cucumber, tomato, and bell pepper plants, as well as some lettuce. On this area, potted plants can also easily overwinter during the winter.

Those who want to grow some ornamental plants in addition to vegetables will need more space. Growing a larger quantity of vegetable plants also requires a larger area. In these cases, our experts recommend 15 to 18 square meters. Of course, there are no limits upwards. Especially for those who want to use the greenhouse for living purposes, our special constructions are available.

Additionally, the height of a greenhouse should not be neglected. A comfortable wall height allows for comfortable and safe work in an upright position. Furthermore, a certain height also supports air circulation. In general, large plants should maintain a distance of at least 30 cm from the roof.

For good growth and high yields, a good climate is needed in the greenhouse. Flexible ventilation and effective shading play an important role in this. Heat and sun, yes, but only in the desired measure.

In order to prevent overheating, a glass greenhouse should be sufficiently ventilated. Large roof and side windows promote air circulation for sensitive plants. We recommend planning the windows opposite each other for good ventilation. Automatic window openers provide adapted ventilation on their own. They operate hydraulically, so no electrical power is required.

The large entrance door provides additional fresh air supply. A divided Dutch door is particularly practical: the upper part of the door can be opened for ventilation, while the lower part remains closed. This way, it blocks pests like snails, as well as pets, from entering the greenhouse.

A glass greenhouse generally requires shading. Without shading, there is a risk of sunburn damage to sensitive plants. Effective shading can be provided by interior blinds. These can be installed under the roof and also on the side walls, and can be adjusted according to the weather. 

For our shading, we use a special white fabric that contains a high silver content through fine aluminum threads. This allows for a high reflection of sunlight, preventing the greenhouse from getting too hot even during midday sun. The fabric is particularly durable, as it is not only water-resistant but also UV stable. Additionally, it is dirt-repellent and prevents the formation of condensation inside the greenhouse.

The greenhouse accessories you choose depends entirely on your gardening and aesthetic preferences. Even in the smallest greenhouse, you can maximize the usable space with the right accessories. Hanging shelves or planting tables create additional space in the greenhouse. With planting trays and shelves, you can work on multiple levels and gain a lot of space. Additionally, year-round use requires shading or heating. You can find a variety of items for all sizes in our online shop for accessories. You can also find a lot of information about this in the guide.

The most important feature is a stable construction. In addition, high-quality glazing and certain quality characteristics are essential. These include the roof load capacity, the standing wall height, and the resistance to storms.

A good example of a very durable greenhouse is our freestanding greenhouse “Bio-Top”. With this model, the width and height can be freely chosen in certain steps. Visual details such as decorative elements or a masonry base can be added during the purchase. With appropriate accessories such as shading, heating, shelves, and more, the greenhouse can be optimally used.

There are many possibilities for planting in a greenhouse. But when is it best to sow, prick out, and plant vegetables such as tomatoes, cucumbers, and others? In our detailed sowing calendar for all types of greenhouses, you will find the best dates for sowing and harvesting.
