We (the technical course of the Herta-Lebenstein-Realschule) designed three different connecting pieces, which make it possible to quickly assemble a greenhouse. You only need profiles with an edge length of 10 mm. We used wood as well as aluminum profiles. Before we introduced the aluminum profiles, we heated the ends beforehand with a gas burner. The larger greenhouse was covered with foil to maintain the airiness and temperature.
You can also bolt the connectors to the profiles, but this is often not necessary.
We wish you a lot of joy with our model.
We would also be very happy about constructive feedback!!!
