Greenhouses offer the opportunity to extend the season for your vegetables.

With a greenhouse, you quickly experience the joy of extending the summer season. You can enjoy the sun in the greenhouse, and the plants benefit from the extra heat and the long warm season. Vegetables can be grown early, and you can harvest crops over time.

A greenhouse also allows you to expand the number of varieties you can grow. It is suitable for many different types of crops, but will be especially suitable for the type that thrives best in a warm climate, such as:

  • Tomato
  • Cucumber
  • Bell pepper
  • Chili
  • Citrus Fruits
  • Melon
  • Grape

In addition, you can use the greenhouse when you are germinating seeds, and as a workplace for transplantation etc.

If you have a greenhouse, remember that:

  • Clean and wash windows, shrubs and surfaces before using the greenhouse after winter.
  • Change the soil due to the risk of pest and fungal infestation.
  • Wait to grow delicate plants in an unheated greenhouse.


Attach the greenhouse to a wooden or steel base or to a molded foundation. A wooden or steel base is the easy and quick solution. If you want a larger greenhouse, it should have a molded foundation.

You should place the greenhouse so it gets plenty of sun all day.

You can take advantage of the light shade found under smaller trees. Then you will be free to shade the greenhouse with curtains or paint the windows. If you have a tree that pops out relatively late, the greenhouse will get plenty of sun all spring.

A purchased greenhouse typically consists of frames with glass, which are assembled for wall and roof modules. The vast majority of greenhouses are made of aluminum profiles and frames.

You can get plain glass greenhouses, which is the most common. You can also get greenhouses with tempered glass or plastic sheets. It is more expensive, but also has extra resistance in stormy weather and resists hard bumps from rocks, balls and fallen branches.

If you buy a finished greenhouse, the price depends on the size and quality

A good and cheap solution is to build a greenhouse of recycled materials, which you can either find at recycling stations or buy online. For example, you can buy windows, frames and coatings.

Old windows with wooden frames and rafters may be worn for the home, but still very useful for a greenhouse. However, this project requires do-it-yourself skills.

Shape and size.

Most greenhouses have vertical sides. The roof usually has a slope of approx. 30 degrees, so the condensation on the inside of the glass can drain off and heavy snow will slide down. However, you can also get greenhouses in many forms

Greenhouses with one-sided roof pitch. These greenhouses are suitable for placement on a house wall, limbs etc.

It is also important that you choose a greenhouse with a good height.

In a high greenhouse, the air is more comfortable; it does not become so heavy due to temperature and humidity. In addition, there is better ventilation in a greenhouse with good height. 150 centimeters will be a suitable height at the sides of the greenhouse, and about 2 meters in the middle.


You can choose many different accessories for your greenhouse.

If you want to grow germinating seeds, it can be difficult in the early spring to create the right conditions throughout the greenhouse. Here breeding boxes are a good supplement because you can easily get a high temperature and humidity in them.

Ventilation in the greenhouse is essential for the well-being of the plants. The greenhouse temperature should preferably vary between a daytime temperature of 25 and a nighttime temperature of 15 degrees. Windows that can open must correspond to at least 30 percent of the floor area.

You can buy window openers that open automatically when the temperature or humidity gets too high.

You can install a window shutter in the sides of a greenhouse. It provides a good even flow of air to the plants and adjusts the air exchange in the greenhouse.

The shade net can be a good solution to keep out the sun’s rays. The more perpendicular the rays hit the glass; the easier the rays will pass through, so a shade mesh will benefit most in the roof of the greenhouse.

You can install various semi or fully automatic irrigation systems in the greenhouse.
