Construction and maintenance of the greenhouses

Type and size

There are two sizes of greenhouses. The large version measures 3 x 5 metres and the slightly smaller ones measure 2.2 x 2.5 metres. They are made of polycarbonate and are so robust that they last more than one season.


A level base is important for the construction of the greenhouses. If the greenhouse is to stand on concrete, drainage must be considered. Concrete also acts like a radiator. If the greenhouses are to stand on a lawn, a base frame/foundation is needed.

Temperature Control with Arduino

The aim is to be able to regulate the temperature of the greenhouses. The air conditioners can only control and maintain a fixed temperature value. They do not have an external temperature sensor. Therefore, there is a possibility to connect an Arduino controller, with which the inside temperature of the houses can be adjusted to the outside temperature quite accurately. You can find the detailed instructions here.
