As a biologist who researched how nature works (find out more about my background in the about us section), I use my knowledge to create unique self-sustaining systems in which water and nutrients are continuously recycled. 

Here’s a quick overview of what makes terrariums function as mini-biospheres: 

• The plants used are carefully chosen so that they thrive in a high humidity environment, but at the same do not grow very fast. 
• The terrariums are closed so that there is minimal water loss, and the water is recycled inside the system. 
• The mini-biospheres also contain decomposers, who feed on dead plant matter and mould, turning them into nutrients for the plants (no need to fertilise).
• The plants produce oxygen for the decomposers, and the decomposers produce carbon dioxide for the plants. 

All the system needs from outside is energy input in the form of light, but not direct sunlight. For more insightful information, see our terrarium tips section.
