Basic Techniques People Use When Constructing 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 you decide to put one together, the next question is often about how to build it and the various materials used. There really is not a catch all answer to this question. There are actually several ways people try which range from using inexpensive materials and go up in under a day to very expensive material that can take months to build. There are even different prefabricated domes you can purchase on the web that have almost everything ready for you 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 use the hub and tube method. Using this rather than bolting all your flattened pipes together you use a larger pipe with several holes drilled inside it. Your studs are carefully bolted to it rather than each other. Finally light weight plastic is then used to cover it. This type is typically stronger while still being inexpensively priced.

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.

A more expensive way to go is the pre-made paneled timber and frame method. This is typically the method most prefab stores use that people find surfing the net. This method uses mostly pre-cut wooden timbers which are made to smoothly connect along all the edges. They also have an outside material used on them to reinforce them and make them stronger.

One of the longest lasting and strongest forms is called the monolithic dome. These have been known to out live many house built next to them. They are generally built with layers of concrete sprayed over balloon forms. They use sprayed polyurethane foam on their interior to help insulate and water proof them. After it all dries all the windows and doors are installed in them.

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.
