What Is A Biodome?

A biodome is a form of controlled, self-sufficient eco-system that closely replicates the natural outdoor environment. It is a scientific based form of a greenhouse that can made up of various geodesic spheres, although it’s not always the case.

It creates its own water, nutrients and survives without any help from the outside. The most famous example, is that of the Montreal Biodome, which houses 4 different eco-systems.

Another famous example can be found in Cornwall, United Kingdom, called the Eden Project which consists of numerous biodomes that span a large area.

A biodome creates a perfect environment for plants, animals and insects, and you can build a mini biodome greenhouse at home with just a few items, just to see how it all works.

Benefits Of A Biodome

A biodome provides many benefits including:

  • It allows you to learn the behavior of all different kinds of plants, insects and eco-systems.
  • You can replicate different eco-systems such as the Desert, the Arctic, the Amazon jungle and others without actually going to those places.
  • You are given the chance to preserve plants and animals and create a beautiful outdoor area that is self-sufficient and sustainable.
  • It also saves money, energy and water because of its regenerative nature.

There are many benefits that a biodome provides to plants and you can notice the positive effects on seedlings specifically:

  • They grow quicker than other seedlings.
  • They are stronger and more resilient.
  • They are more likely to survive transplanting into the garden.
  • There is less chance for viruses and bugs to attack the plants.
  • The plants do not suffer from burning, or receiving too much or too little of a certain nutrient, as the biodome is not tampered with or exposed to the outside environment.

Differences Between A Biodome & A Conventional Greenhouse

A biodome is very similar to a conventional greenhouse. After all, both environments are controlled and allows all different types of plants to thrive. However, a greenhouse is very different to a biodome in a number of ways.

what is a biodome

  • A greenhouse may or may not be biologically isolated from the outside world, which means that there’s an on-going exchange of elements such as fertilizer, water, oxygen with the outside world.
  • A biodome is the complete opposite. Everything is self-supported and once closed up and sealed from the outside world, the entire life cycle process continues on its own.
  • A greenhouse is generally used for raising plants (with the exception of having an aquaponics system inside) whereas a biodome can be used for raising all different kinds of animals.
  • You’ll find that because biodomes are used for raising plants alongside animals, they generally tend to be bigger in size in comparison with greenhouses.


You shouldn’t confuse biodomes with geodesic greenhouses, as they are often of the same shape but have different concepts as described above.

Whether you decide to build a biodome or a conventional greenhouse, the implementation of both hydroponics and aquaponics systems are ideal for either because they make the most of the interior space. What’s most important is that the structure is built correctly with the right materials for your intended purpose.
