Build greenhouse: you have to pay attention to this

Frost -sensitive garden plants find a warming and protective quarters and vegetables in the greenhouse, if there is hardly anything grows in the garden outside in the garden.Tips on the location, foundation and greenhouse heating are available here.

Überblick

A greenhouse enables weather -independent gardeners.In addition, the hobby gardener makes it a lot of work: be it as a winter quarters for plants or as a place to prefer vegetables and spring flowers.There are a few points to clarify in advance.

The right location for a greenhouse

It is important that the greenhouse is in a bright place in the garden, says book author Karla Krieger.Shadow spaces such as under trees that lose their leaves should avoid.However, if the greenhouse is a little shade of a tree crown during the summer months, this can also be an advantage.Then it doesn't heat up quite as much.

Also, the greenhouse should not be too close to walls and hedges.This means that the construction in these areas does not get a sun.In addition, the location does not circulate correctly by the location, so that moss and algae form.

Also make sure that the greenhouse is not too much in the wind.This means that it can cool down in winter.

Protect the greenhouse from frost

In winter the greenhouse should be protected from strong frost.For this, for example, it is enough to attach a multi -layer nop film to the greenhouse.It protects against harmful UV radiation and holds cold.You can seal smaller gaps with a silicone spray.A wind protection hedge also improves the situation at a sufficient distance.

In addition, you should make sure that there is no or only a little snow on the roof of the greenhouse in winter.On the one hand, the plants stored in it are prevented so much.On the other hand, it may be that the statics of the house are not sufficient to carry the snow load.

The right size for the greenhouse

Experts recommend a size of at least twelve square meters.This makes it possible to move in the greenhouse.Also make sure that you have enough space to grow.

In addition to the area, you should not save at the height.On the one hand, for example, cucumbers and tomatoes need to grow, on the other hand, otherwise it cannot be worked on.Two meters are at least required.

Put on the right foundation

For a greenhouse you should choose a concrete strip foundation.That means: long -drawn concrete strips under the walls that go into the ground.This construction can prevent faults.In addition, the floor within the house does not freeze in winter.Another advantage of a real foundation is that mice do not penetrate from the outside and rummage through it.

In addition to the right foundation, styropic insulation also protects against frost.

The less complex alternative is a point foundation.It is a compromise for the rented garden, it is easier to remove again.In the case of a point foundation, the garden house is only on point by point on individual foundations.The simplest solution for this is metal pods that are driven by the ground.It becomes more stable when you make excavations and fill with concrete.

You can achieve a good insulation effect when you grow the greenhouse directly to the house.

The right material: glass, film or plastic?

A greenhouse is mostly built from aluminum profiles.Many forms can be realized with them, explains Jörn Pinske, gardener and author."In comparison, wood is much more expensive and not as durable," added Krieger.It is also quite maintenance -intensive."You only use it for luxury greenhouses," says Pinske.

For the panes you should fall back on glass.It is stable and enables ideal sunlight.The plants get enough light.However, glass is more expensive and difficult in assembly.When building the greenhouse, you should therefore work with another person.Another disadvantage is that glass, without the corresponding coating, is not breakproof.

Plastic slices are stable and easy to assemble.In terms of price, however, they are not much cheaper than glass;At least if you rely on high -quality products.The advantage over glass: plastic slices can be easily assembled and have better insulating properties.

Foil is rarely stable enough and can tear down in difficult weather conditions.However, film is very cheap.If you only want to use the greenhouse for one season, you can use this material.

Special coating prevents algae

Plastic is mainly used for the covering, the dub double plates isolate the greenhouse well.You should be between six and 16 millimeters thick.The denser the plates are, the more stable they are and the better the thermal insulation of the window is.According to warrior, a no-drop coating of the panels prevents the formation of algae.

A greenhouse should have a gutter."This way you can catch the rainwater and get the best irrigation water for the plants," explains Pinske.And the gutter increases stability.

It is best to automatically ventilate the greenhouse

Windows on a shady wall and in the frozen roof area create a fireplace effect that ensures that warm air escapes and fresh air flows.In addition, an air circulation is recommended.The Gärtner Pinske recommends the automatic window opener.The windows are opened using a wax cartridge - without any electricity consumption, because the wax expands with warmth.The regular ventilation of the greenhouse prevents a heat that is harmful to the plants and the development of fungal diseases by too high humidity.

Guach house heating: advantages and disadvantages of the systems

Whether you need heating for your greenhouse depends on various factors:

If you also use the greenhouse in winter, you need a heating in addition to good insulation.So the temperatures in the construction do not drop below three to five degrees.Unheated greenhouses only remain frost -free at outside temperatures of up to minus five degrees: a danger to plants, the irrigation system and the material of the greenhouse.A heater can therefore make sense.

Hardy plants, which are to be protected from the weather, also feel comfortable in a well -insulated greenhouse in winter.

Electrical or gas heating is particularly suitable as a heating source for the greenhouse."The gas heating is not tied to central care because it is operated with bottle gas," explains Krieger.But you absolutely have to ventilate the exhaust gases regularly.So that the heat can be distributed evenly with this type of heating, a circulation device is needed.The same arguments are also available for or against oil heating.An electric heating is better here, it can be regulated well.A fan distributes the heat evenly from bottom to top.

Pinske recommends placing black hoses filled with water between the plants on the floor.They also warm the surroundings because they store the heat of the sunlight.But that is only a supplement to the heating, not your replacement.

It is also possible to heat the greenhouse with a solar heating.Then, however, the corresponding areas must be available on which you can install the solar collectors.If you already have a corresponding system to generate heat for your house, you can also heat the greenhouse via appropriate lines.
