One advantage of a geodesic dome greenhouse is that it can be easily constructed. However, this also comes with a weakness: It requires regular maintenance and repairs. The dome is built using struts that are typically 1-2 inches thick and 2-4 inches wide, which can be susceptible to rot. Like other greenhouses, the cover can tear, and other parts may also require maintenance. Let’s discuss repairing a geodesic dome greenhouse.
Last fall, we uncovered the geodesic dome to rebuild it completely. However, we realized it was too big of a project due to health reasons. We decided to replace all the rotted struts and cover the dome anew. This experience showed us the advantages of a geodesic dome structure. As we mentioned in the review, a geodesic dome greenhouse is a great option for DIY enthusiasts due to its lower cost. However, it requires ongoing maintenance and attention.
Different types of connections offer different options
Geodesic domes can be built using different connection types. On the Acidome Calculator, you can choose which one you prefer. However, the different types will also affect whether or not a dome can be easily repaired.
We built our first dome using cone connections. I thought it looked the most unique, and it does. However, it turned out to be the most difficult one to repair. It is not so easy to take a strut out without disassembling the whole dome. Joined connections would be similar.
For our second dome, we used DIY pipe connectors. These connectors have proven great for repair. Each strut can be easily removed and replaced with a new one if needed, and the pipes themselves have held firm so far.
Building separate triangles (GoodKarma) is another relatively easy method of building and repairing. Although, you will have to replace a whole triangle. Here is a good video that shows that.
Repairing or replacing the cover
A greenhouse’s cover must be hail-proof or easily replaceable, especially in our hail-prone area. Greenhouse plastic does not withstand hail.
Thankfully, the geodesic dome structure again is a good option. In case of hail or frost damage, single triangles can be replaced without redoing the whole cover.
It is advisable to get more cover than needed at the beginning so that there is covering material available if needed. However, this is still much less expensive than replacing the whole cover. Read more about covering a geodesic dome greenhouse here.
Other repairing projects
Windows and doors may also require repairs. Since the entire dome is built using a do-it-yourself approach, replacing anything that needs fixing is usually straightforward. In our second dome, we even added windows as an afterthought for more ventilation, which was no problem.
