There are several types of greenhouses that you can search online or in the market. Do you want a free-standing structure or do you prefer one attached greenhouse? Both accompanied by some advantages and some disadvantages.
Choosing one or the other should be comprehensively dependent on your needs as a grower. Choosing the wrong type of greenhouse may prove more costly in the long run. If you are searching for ‘Greenhouse’ (which is also known as ‘Växthus’ in the Swedish language) then you can visit various online sources.
An attached greenhouse can be a lean-to and can be very cheap in terms of treatment. It does not cost much to provide lighting and heating and water sources because it can easily adapt to whatever resources you have at home.
On the other hand, it can also limit the types of plants you can grow because of limited space and also have maximum exposure to the sun.
The free-standing structure of the greenhouse may be very good for you if you plan to grow various crops. However, it can be expensive, especially during the winter months to keep the temperature and greenhouse irrigation.
Given all of this, both your needs and your budget should be considered to build a cheap greenhouse.
