Respective Techniques People Use When Building A Geodesic Dome Greenhouse

By Patrick James


It is a well known fact that people as a whole enjoy raising their own gardens. There is something special about planting your seed in the earth and a few months later eating the fruits of your labor. In some colder climates people are recently rediscovering the benefits of greenhouses to help extend the growing period. Knowing the assorted construction methods for building a simple geodesic dome greenhouse may be beneficial should you try to build one.

After deciding on building one generally the following question is regarding how are they built or what materials can I use. There is not a simple answer to these questions. There are several different methods people use that will range from quite inexpensive materials which go up in about a day, to much more expensive materials which take longer to build. There are also prefabricated models which you can find on the internet that have everything cut and marked to build.

Some people like the inexpensive flattened conduit method. It is probably the easiest. You flatten out the ends of metal tubing you buy at the store. Then you drill a hole at both ends for a bolt to go through and bend it just a little. After construction it is generally covered with light weight plastic. Domes like this can generally go up in under a day.

Some prefer the tube and hub methods. With this one rather than bolting together the flattened pipes, a larger diameter pipe with holes drilled into it. The studs are bolted to the larger pipe instead of each other. Afterwards it is completely covered with a light weight plastic. Generally this is slightly stronger while still being affordable.

Some people like the beam and hub method. This is more complex and expensive because it uses specially cut beams and hubs that are connected to form a framework for the dome. Permanent domes are generally constructed this way.

One of the more high priced ways to try is the framed paneled timber method. This method is generally the way many prefab companies will ship to people that can be found on the internet. They use pre-cut wood timbers that are constructed to link together smoothly along the sides. They will generally have outside materials attached as a means to reinforce them for strength as well.

One of the most durable and longest lasting kind is the monolithic dome. They will typically outlive most houses they are built beside. They are typically built with several different layers of cement heavily sprayed over balloon forms. They are also sprayed with a polyurethane foam inside them to act as waterproofing and as thermal insulation. After everything dries out they are fitted for the windows and doors.

People are not required to use only a single technique when building their geodesic dome greenhouse. By realizing how each technique is used there is always the possibility of combining the best parts from all of them. Remember to, that while they do make great greenhouses, they also make fine sun rooms to spend time in as well.
